URT Releases 7” TFT LCD Displays with LVDS Interface

Consumers are demanding more realistic video, 3-D graphics and photo-realistic images in the office and in the home. Solutions exist today to move this high-speed digital data both on very short and very long distances: on a printed circuit board (PCB) and across fibre or satellite networks. Moving this data from board-to-board or box-to-box, however, requires an extremely high-performance solution that consumes a minimum of power, generates little noise (must meet increasingly stringent FCC/CISPR EMI requirements), is relatively immune to noise and is inexpensive. Unfortunately existing solutions are a compromise of these four basic ingredients: performance, power, noise, and cost.

LVDS which stands for Low Voltage Differential Signalling addresses this need. It is a way to communicate data using a very low voltage swing (about 350mV) differentially over two PCB traces or a balanced cable. LVDS is a low swing, differential signalling technology which allows single channel data transmission at hundreds or even thousands of Megabits per second (Mbps). Its low swing and current-mode driver outputs create low noise and provide very low power consumption across frequency.

URT introduces its new 7” TFT LCD displays with LVDS interface and with 800xRGBx480 dots resolution, 262K colour depth, and touch panel interface. Module size (W x H x T) is 163.9 x 103.95 x 9.35 mm while viewing area is 155.2 x 94.24 mm.  This new display has transmissive LCD type, LED backlight, built-in timing controller, and DC/DC converter.  Key specifications include typical current consumption of 150mA, maximum response time of 20ms, typical viewing angles of 140oC horizontal and 110oC vertical, high brightness of 350 nits (typical), and contrast ratio of 400:1 (typical).

To interface this TFT LCD display with analogue video (NTSC/PAL/SECAM with Composite or S-Video interface) or PC VGA signals, you can use the URT A/D Driver Board TMS-9083 (see next article in this newsletter).
