A TFT-LCD AV controller refers to an electronic device or integrated circuit (IC) that is designed to control and manage the functions of a TFT-LCD (Thin-Film Transistor Liquid Crystal Display) screen in the context of an audiovisual (AV) system. This controller is responsible for processing and displaying audio and video content on the TFT-LCD screen.

Part Number: HX8806, HX8806LA

Description

The HX8806 is a timing controller for small panel TFT-LCD. It provides horizontal and vertical control timing to TFT-LCD source and gate drivers. Built-in vertical synchronization detection circuit generates vertical synchronization signal internally without the extra components.

Built-in phase lock loop sub-function with external VCO and low pass filter produces system clock which synchronizes input composite synchronization signal. The device also provides 8 different zoom in/zoom out display modes for 2 different display resolutions.

 

Features

1. Programmable resolution mode.

2. Master clock frequency: 30 MHz max.

3. Built-in vertical sync. detection to omit the external sync. separator.

4. Supply voltage: +5.0V or +3.3V.

5. Shift clock signals for the source driver (3-φ Clock).

6. Line inversion driving scheme.

7. Support NTSC/PAL TV system.

8. Provides control timings for source and gate drivers.

9. Provides flip and mirror scan control.

10. Built-in zoom in/zoom out display mode selection.

An SXGA LCD controller is a device used to control an LCD (Liquid Crystal Display) panel with SXGA resolution. “SXGA” stands for Super Extended Graphics Array, which is a display resolution standard that typically refers to a resolution of 1280×1024 pixels.

The controller takes input signals, which could be digital or analog video signals, and processes them to drive the individual pixels of the LCD panel. It ensures that the correct colors and brightness levels are displayed at each pixel to create a coherent image on the screen.

Part Number: TSUM16AK

Function: SXGA LCD Controller

Package: PQFP 128 Pin Type

Manufacturer: Mstar Semiconductor

Description

The TSUM16AK is total solution graphics processing IC for LCD monitors with panel resolutions up to SXGA. It is configured with a high-speed integrated triple-ADC/PLL, a high quality display processing engine, and an integrated output display interface that can support LVDS panel interface format. To further reduce system costs, the TSUM16AK also integrates intelligent power management control capability for green-mode requirements and spread-spectrum support for EMI management

The TSUM16AK incorporates the world’s first coherent oversampled RGB graphics ADC in a monitor controller system. The oversampling ADC samples the input RGB signals at a frequency that is much higher than the signal source pixel rate. This can preserve details in the video signal that ordinarily would be lost due to input signal jitter or bandwidth limitations in non-oversampled systems.
