4D Systems launches touch screen LCD TFTs

4D Systems has launched a further two displays which are based on the company’s PICASO-SGC and PICASO-GFX2 graphics processors.

The uLCD-32PT(SGC) and uLCD-32PT(GFX) have a 3.2-inch, 240 x 320 pixel, LCD TFT display with touch screen and 4D is touting them as the most flexible touch screens on the market.

They have a 5 pin interface to any host device as well as being able to support external SD/µSD memory cards for storing images, video files and other data. Both include a dedicated PWM Audio pin that supports FAT16 audio WAV files, an on board audio amplifier and speaker and support for “all available Windows fonts and characters.”

Additionally the uLCD-32PT(SGC) has a serial interface to any host micro-controller that can communicate via a serial port and 16 GPIO pins.

The PICASO-GFX2 chip, which is embedded in the uLCD-32PT(GFX) display lets user write applications using 4DGL, which the company says has syntax similar to popular languages such as BASIC, C and Pascal.

This technology can also be used to develop applications that run stand-alone on the display. In addition the uLCD-32PT(GFX) includes 15K bytes of flash memory for user code storage and 14K bytes of SRAM.

The two new launches by 4D follow an announcement last week by the company when it launched two 1.44 inch LCD TFT display modules based on its GOLDELOX-SGC and GOLDELOX-GFX2 graphics processors.
