Emerging Display Technologies (EDT), available from Glyn High-Tech Distribution, has introduced new RoHS-compliant versions of the 3.5” and 5.7” transmissive colour TFT LCD modules, with options for integrated DC/DC converter circuitry and 4-wire resistive touch panel.
Both TFT LCD modules have a QVGA resolution (320 x 240 RGB pixels), 16.7 million colours (24 bit), digital parallel RGB interface, white LED backlight system, operating temperature range of -10°C to 60°C, and 3.3V power supply. The 3.5” module has an operating current of 200mA (typical).
Both modules have excellent visibility in bright and low light conditions, with a typical brightness of 250 cd/m2 for the 3.5” module and 195 cd/m2 for the 5.7” module. In addition, both modules have a 6 o’clock viewing direction, high contrast ratio of 300 (typical) and wide viewing angle of 67 degrees (typical).
Active area dimensions are 70.08W x 52.56H mm for the 3.5” module and 115.2W x 86.4H mm for the 5.7” module. Module size dimensions are 76.8W x 63.8H x 4.4D mm for the 3.5” module and 124.7W x 100.0H x 7.5D mm for the 5.7” module. Dot sizes are 0.073W x 0.219H mm for the 3.5” module and 0.12W x 0.36H mm for the 5.7” module.
These TFT LCD modules are ideal in a wide variety of applications such as point-of-sale equipment, barcode scanners, GSM/navigation devices, PDAs, handheld game consoles as well as portable medical equipment. These modules have also been tested for durability (over 1,000,000 times of stylus hitting and over 100,000 times pen touch sliding), making it suitable for rugged applications.
