A new high resolution display module not only provides excellent optical performance, but also allows the user to control backlight brightness, increasing unit life and saving energy.
 
The Hitachi Europe Ltd’s TX20D28VM2BAB has a display resolution of 800 x 480 pixels (WVGA), an integrated LVDS data interface and integrates robust high brightness LED backlights in medium size TFT display modules.
 
The white LED backlight helps to provide excellent image uniformity and delivers a brightness of 550nits with a half brightness lifetime of 40K hours. A contrast ratio of 600:1 ensures display images are clear and bright.
 

 
 
Ideal for applications in high brightness environments where the lifetime of the backlight is not a critical requirement, the user has direct access to the LED backlight driving circuit. By driving the LEDs with a current of 20mA, a higher brightness of 900nits can be achieved. This will however reduce the half brightness lifetime of the backlight to typically 20K hours.
 
The 15:9 wide aspect ratio format allows graphical user interfaces to be designed for many different application environments while the LVDS interface aids ease of integration with single board computers.
 
The display module features compact dimensions of 189mm (w) x 120mm (h) x 7.5mm (d) and weighs 170g. A 20-pin LVDS data interface supports a colour palette of up to 262k colours. The display module will operate safely and reliably at temperatures between -20°C and +70°C.
