At GDP, we understand that some of the verbiage used on our site may not translate well if you're not familiar with our industry's jargon. So we're here to lay it out for ya and tell you exactly what means what. That way you'll know what we mean when we say something is "OEM". This will give you a better understanding of what you're looking at so you know exactly what you're purchasing.


Status: In Stock
When a product is labeled as "In Stock", it means the item is currently in stock and available for same-business-day shipping. Please note however, that if the order is placed after our cut-off time of 4:30 PM CST [Central Standard Time], the order will be shipped the following business day. Everything we sell ships from our offices in San Antonio, Texas.
Status: Backorderable
Any product labeled "Backorderable" is one that is not consistently in stock [due to either age, popularity, etc]. It will be shipped to you within the designated amount of days stated after being tested. Please note that this is a shipping time frame, not a delivery time frame. Once your item has been shipped within the designated time frame, it will be delivered pending the shipping speed you chose upon checkout. Another note: if we have an inbound stock shipment of the item you've ordered with this label, we will allocate the item to your order before receiving it as stock. This helps us get the part to you quicker. Everything we sell ships from our offices in San Antonio, Texas.
Free Shipping
Free Shipping is exactly that - shipping that's free. However, there are a few stipulations to that. A qualifying order must be greater than $99 (before tax) AND not weigh over 2.5 lbs. This applies to all parts, but especially to heavier parts like Chromebook housing components, chargers, displays and batteries. When ordered in modest volume, these orders will not qualify for free shipping due to their weight. Furthermore, if an order consists of both in-stock and backordered parts: orders with the free shipping option selected will be held until the order can be shipped complete.


Quality Assurance: Tested / Inspected
At GDP, we put all our parts through quality and functionality testing. We physically inspect and test each part for cross-compatibilities, defects, physical scars, and functionality. Most screen assemblies, as well as internal components and cosmetic components, are bench tested on original cellular handsets, Chromebook or wireless device.
Manufacturing: OEM / Original
Often we'll use the abbreviation OEM, which means Original Equipment Manufacturer. When we say OEM, we're saying the part, majority of the part, or major components of the part were assembled with OEM components by the manufacturer that made the device, including parts with Logos. For example: an "OEM Samsung Galaxy S III AMOLED & Digitizer Assembly" is a part that was manufactured by Samsung. No cheap knock-offs here.
Manufacturing: Aftermarket
This term is used when a part is made by a party other than the original manufacturer, or OEM. Although some parts may be aftermarket, we test each part to ensure full functionality and often a part we state as Aftermarket, may be constructed with some OEM components in them. If a part does not meet our quality standards we will not ship it to you. That being said; the aftermarket parts we offer do NOT have any manufacturer logos. For example: The "Aftermarket Complete Rear Housing Compatible with Apple iPhone 5s" is an aftermarket part that does not have any manufacturer logo. Selling aftermarket parts that are branded with manufacturer logos is very much illegal, and we will NEVER intentionally sell them.
Condition: New / Like New
This is the physical condition of the part. Which means they are either brand-spankin'-new, or at least as close to that as we can get. This condition is sometimes referred to as "A" Stock.
Condition: Reclaimed
This is the physical condition of the part. Which means they may have light physical damage such as scuffs or scratches which deny them the New or Like New status. Although the parts may have minor damage, we test each part prior to shipping to ensure the part works as intended so you can feel good about the purchase you've made. This condition is sometimes referred to as "B" Stock.


A LCD [Liquid Crystal Display] is the part of the device that displays all the graphics. This part does NOT provide touch input.

Commonly referred to as:

  • LCD Screen
  • Screen
  • Display
A Digitizer is the part on the device that allows touch and/or stylus input. This part is typically made of glass or plastic and sits on top of the LCD.

Commonly referred to as:

  • Digitizer Touch Screen
  • Digitizer Touch Panel
  • Touch Panel
  • Digi
  • Digitizer Glass
  • Lens [A lens is different from a digitizer. We typically use the term "lens" for plastic, non-touch panels.]
An AMOLED [Active-Matrix Organic Light-Emitting Diode] is similar to an LCD in that it is the part of the device that is used to display all the graphics. One difference between the AMOLED and LCD are the power consumtion; typically AMOLED uses less power because black colored pixels are actually off rather than displayed as black like LCD does. Another difference is AMOLED has higher refresh rates that increased response times of when graphics are displayed.

Different types of AMOLED:

  • Super AMOLED
  • Super AMOLED Advanced
  • Super AMOLED Plus
  • HD Super AMOLED
  • HD Super AMOLED Plus
  • Full HD Super AMOLED
LCD & Digitizer Assembly
This assembly is just that; the LCD and the digitizer come pre-assembled to make for an easy repair. Sometimes the LCD and Digitizer are pre-assembled with the front housing attached as well. Examples include; the Nokia Lumia 920 LCD & Digitizer Assembly, or Samsung Galaxy S4 R970, i545, L720 AMOLED & Digitizer Assembly with Front Housing.


Front Housing
The front housing of a device is usually the housing component that secures the LCD/AMOLED and/or Digitizer assembly in place. It often is connected, screwed, or adhered to the rear housing or mid-plate. Some devices have AMOLED & Digitizer Assemblies that are compatible with all models of the device, like the Samsung Galaxy S III. However, once the front housing is combined with the assembly, the compatibilites begin to vary.

Commonly referred to as:

  • LCD Tray
Rear Housing
The rear housing is opposite of the front housing. It attaches to either the front housing or the mid-plate and encapsulates the inner components in place while providing an attachment for the battery door. Depending on the device, the rear housing may be the entire back piece of the device. The HTC Windows Phone 8X does not have a battery door, instead the entire rear piece is considered the rear housing.
Battery Door
A battery door is the removable exterior part of the device that closes the device and shields the battery and other small components.
A bezel is simply a frame for any given component of a device. Whether it's a camera bezel, or a housing bezel. For example, the BlackBerry Bold Touch 9900, 9930 Chrome Bezel is the part that fits around the entire sides of the device.


A camera is a part that takes or records pictures and videos.
Front Facing Camera
The front facing camera is just that; the camera on the front of the device that faces the user.
Rear Facing Camera
The rear facing camera is simply the camera on the back of the device that faces away from the user.


An antenna is a wire or cable that provides different types of information for the device.
Cellular Antenna
A cellular antenna is one that provides the device with mobile data. Data is used for placing calls, texting, web browsing [when not connected to Wi-Fi], etc.
Wi-Fi Antenna
A Wi-Fi antenna is one that provides Wi-Fi connectivity to the device. Usually, Wi-Fi is much faster than cellular data and does not eat up your precious gigabytes of data allowance on your cellular carrier's plan.
Bluetooth Antenna
The bluetooth antenna provides bluetooth connectivity to other devices that can be paired via bluetooth such as other phones, car kits, headphones, etc.
GPS Antenna
A GPS [Global Positioning System] antenna is the antenna that allows the user to use any gps navigation applications.


Flex Cable Ribbon
A flex cable ribbon, a.k.a "flex", is a flat, flexable ribbon with conducting wires running down it that provide information or data to be sent from one component to another. There are many variations / uses of a flex cable ribbon.
Power Button Flex
A power button flex is the flex that allows your device to be turned on, off, reset, etc. Typically they are a little clickable button attached to a flex cable ribbon similar to the Samsung Galaxy S III i9300 Power Button Flex Cable Ribbon.
Volume Button Flex
The volume button flex, just like the power button, has clickable buttons for volume up, down, etc. that are usually attached to a flex similar to the HTC Sensation 4G Volume Button Flex Cable Ribbon.
Sensor Flex
The sensor flex is typically a flex cable ribbon that has a tiny sensor, usually a proximity or light sensor, on it. It's used for sensing when things are near or far from it to allow additional functionality to your device like turning off the screen when you're on a phone call.
Motherboard Flex
A motherboard flex is normally just a flex cable ribbon with connectors or contacts on each end that connect one component of a device directly to the motherboard.
LCD Flex
The LCD flex is the flex cable ribbon that connects the device's display to the motherboard. If the LCD flex is not properly connected, the motherboard and LCD will not communicate and no graphics will appear on the LCD.


Speakers are the small components in devices that allow for audio output. Whether you're listening to music, playing a game, or watching videos, the speakers give you all the sound.
Ear Speaker
An ear speaker is the speaker on the front of the device near the top. It's the speaker that is, you guessed it, right next to your ear to allow you to hear the other person during a phone conversation, etc.
Loud Speaker
The loud speaker is usually on the back of the device. However some devices, such as the new HTC One, have front facing speakers. Loud speakers are the ones that are generally used for media playback such as videos, music and games. They are typically a bit larger in size and generally louder than their ear speaker counterpart. They also come in larger pieces, such as the LG Google Nexus 4 E960 Loud Speaker Module which is encased in a small piece that fits inside the rear housing of the device.
A microphone is the tiny little component that usually sits near the bottom of the device that's used for audio input such as talking on the phone or giving voice commands. They are sold alone, however often times they will come on other components like the Samsung Galaxy S4 i337 Charging Port PCB with Flex. This part is the charge port, but on the back of the PCB board sits the tiny microphone.
A jack is usually the 3.5 mm earphone jack. It's what is used to plug in any compatible 3.5 mm earphone, headphone or other audio jack. When you plug in headphones, the audio jack allows sound to be played through the headphones, earphones etc.

Commonly referred to as:

  • Earphone jack
  • Headphone jack
  • Audio Jack


Charge Port
A charge port is a tiny port found on the exterior [but still inside] of a device. It is used as a socket to connect your charging cable which allows for charging the battery. Like the microphone, it is sold alone, however often times they will come attached to PCB boards like the Samsung Galaxy S4 i337 Charging Port PCB with Flex.
SIM Card Reader
SIM card readers do exactly what their name implies; they read SIM card for devices that support them. They are usually part of a PCB that connect to the motherboard, or are part of the motherboard, such as the Samsung Galaxy S III i535, R530 SIM Card & SD Card Reader Contact. As you can see with this part, it also comes with an SD card reader attached which, yep, reads the SD card you may have in the device. Without a functioning SIM card reader, your device may not be able to make calls or be activated on some cellular carriers such as AT&T.
A keyboard is the interior PCB that contains all the little clickable buttons of a physical keypad which send each letter or symbol's information to be displayed. It is normally found under the keypad. An example of a keyboard is the Motorola Droid Pro XT610 Keyboard.
Unlike the keyboard, a keypad is the exterior part of the device will all the number, letter and symbol keys on it that are used for text input on the device. Often times there will be combinations of the keyboard and keypad like the BlackBerry Bold Touch 9900, 9930 Keyboard & Flex Cable Ribbon & Keypad Assembly. It has the physical keys that you press for physical input, and under it is the keyboard PCB.
A PCB [Printed Circuit Board] is the [usually] green board that has all the little integrated circuits and printed circuitry on them. They are often charge port PCBs, motherboards, daughter boards, sister boards, or navigational boards. By looking at the HTC EVO 3D Navigation Light PCB Board, the Samsung Captivate Glide SGH-I927 SIM Card & SD Card PCB Board, the Apple iPad 3 Audio PCB Board [Wi-Fi + Cellular] or even the Samsung Galaxy S4 i9500 Charging Port PCB with Flex you can see how versatile a PCB can be.
