Is a fully integrated, monochrome display that is ready for production. Amulet’s Graphical OS Chip and all the other parts to drive the LCD are mounted directly to the PCB. AOB modules are available in three display types and include an integrated touch panel, white LED backlight and an 8megabit serial data flash chip for storing µHTMLT pages. Furthermore, included is an on-board circuitry that allows the contrast and backlight to be programmed via HTML. This feature provides many options. For example, you can have the user control the backlight through on-screen graphics, or program the GUI to turn off the backlight during periods of inactivity, or even restore backlight and contrast from FLASH presets upon power-up. Modules are RoHS compliant.

A controller board is a piece in an electrical circuit that interfaces with a peripheral object by connecting the computer to it. The connection may be with other computer parts, such as the memory controller, or with an external device, like a mouse, that acts as a peripheral controller for an operation of the original device.

The LCD controller board is often called the Analog/Digital (A/D) board. As a type of hardware processor, it allows for various video source inputs to be connected, selected, and displayed on the LCD screen. It does this by converting the different video input signals into a format manageable by the LCD panel.

In conjunction with the LCD controller, the LCD driver is a form of software that is the interface of and dependent on the controller piece. Combined, the two form an LCD controller driver board. As the controller connects the computer to the operating system (OS), the driver facilitates that communication. Though there is typically just one display controller per LCD, there can be added drivers to extend the reach of the drive to further segments of the LCD.

To generalize the process, the LCD controller/driver adjusts the input signal, scaling resolution if needed, and then outputs the signal for the LCD monitor to use. Some of these output interfaces are low-voltage differential signaling (LVDS), SPI, I2C, and Parallel.

In most LCD controller/driver boards, there are two other input/output systems. Both these systems, however, are two-way pathways. One involves controlling and monitoring options, such as controls for brightness, image, and color using the on-screen display (OSD) control panel. The other is for communication via connections like Ethernet, Bluetooth, or IP.

With modern developments, touch screen devices have become much more prominent, and so the touchscreen controller has as well. There are two types of touchscreens: the resistive one that measures pressure and the capacitive one that reads touch. In both of these, there are sensors that detect the touch signal which then transmit the signal data to the controller. The controller then processes the command for the OS.

To delve deeper into the details, consider the previously mentioned input signals. There are a variety of signals that LCD technology processes, such as VGA, HDMI, DVI, and DisplayPort. These computer display standards vary in format and characteristics like aspect ratio, display size, display resolution, color depth, and refresh rate. One of the biggest differences between these standards is their usage of analog signals or digital signals.

The HDMI is a combination of digital audio and digital video transmission. There are many HDMI connectors, such as the standard, dual-link, and micro. These connectors are what the input signal travels through to reach the LCD controller and to direct what to display.

And last from the list of examples of input signals is the DisplayPort. It is similar to HDMI in its purpose to replace outdated VGA and DVI as well as its transmission of audio and video through its interface. The DisplayPort does not have as much variation in cables and connectors as the HDMI, with only one cable and two types of connectors. From the DisplayPort, there is a growing technology called the embedded DisplayPort interface, or eDP interface. LCD manufacturers have begun to gravitate towards this interface due to its fewer connections, smaller size, and ability to quickly transmit high quality displays.

Bringing the subject back to LCD controllers, with the various types of computer display standards, the video signal inputs can be a challenge to accommodate and translate for the LCD panel, but with the help of adapters and the growth of these standard types, displays continue to become faster and develop with greater resolutions.

I"ve tried searching for controller boards for the LCD model from the teardown article (iPad Mini Wi-Fi Teardown), but to no success. Does anyone know if it"s even possible to do this? Would it be possible to find one and ask the seller/manufacturer to put custom firmware on it? Being a Samsung display, I"m a bit surprised it"s so hard to find, but it"s also a very old device.
