CM501 LCD Driver

The CM501 generates all the supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in TVs and Monitors. It includes boost and buck regulators, VGH and VGL charge pump regulators, gate pulse modulator (GPM) , HV LDO, voltage detector (XAO) and VCOM OP. The CM501 can support input voltage from 8V to 14V and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supply.

MTV038N datasheet

Description :

MTV038 is designed for CRT/LCD monitor applications to display built-in characters or fonts onto monitor screens. The display operation occurs by transferring data and control information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as character background, bordering, shadowing, blinking, double height and width, font by font color control, character but ton boxes, frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, windowing effect, shadowing on window and full-screen self test pattern generator.

Block Diagram


1. Horizontal SYNC input up to 150 KHz
2. On-chip PLL circuitry or external pixel clock input up to 150 MHz
3. Full screen self-test pattern generator
4. Double character height and/or width control
5. Programmable positioning for display screen center
6. Software clears bit for full-screen erasing
