Sunlight readable LCD TFT panels


With more and more displays being used outdoors, sunlight readability is becoming a critical factor in the Digital Signage market.

As well as its optically bonded range of displays CDS has announced the availability of some new high brightness sunlight readable TFT LCD modules. They include the 15.6″ and 15.0″ which deliver very high levels of screen luminance resulting in exceptional picture sharpness and clarity in high brightness environments.

The 15.6″ is a sunlight readable LCD module with a VHB (very high brightness) LED backlight. The LED backlight enables a maximum screen brightness of 1,800cd/m². At this brightness the power consumption of the backlight is 29 watts. Typical contrast ratio is specified as 500:1.

The 15.6in display module has a resolution of 1,366 x 768 pixels with a viewing angle of greater than ±80° in both horizontal and vertical directions. The module has mechanical outline dimensions of 363.8mm x 215.9mm x 14.3mm.

The 15.0″ has 1024 x 768 pixel resolution, sunlight readable display with a VHB LED backlight in a side mount package of less than 12mm maximum thickness. At the maximum backlight power of 18.5watts it  delivers a brightness of 1,500cd/m² and a contrast ratio 800:1.

Standard colour TFT LCDs are often unable to provide sufficient luminance for viewing under bright, outdoor environments and the result is poor image quality. Our LCD display modules are high performance products designed specifically for use under high ambient light conditions. The high brightness LED backlights ensure the display image is easily readable even under direct sunlight.”

The half brightness lifetime of the VHB backlight in these panels are rated at 50,000 hours. The half brightness lifetime is the number of operating hours before the backlight luminance drops down to 50% of its initial value.

Our high brightness backlights are engineered to provide the largest possible dimming range. For applications in low lighting environments, the screen brightness can be reduced to less than 5cd/m² using an LED backlight controller with PWM (pulse width modulation) dimming control.

Both modules feature an anti-glare hard coating (3H) treatment on the front surface of the display and an operating temperature range of 0°C to 50°C.

The 15.0″ and 15.6″ display modules are ideal for high brightness environments and outdoor applications such as digital signage, outdoor kiosks, marine, medical, mobile and industrial applications.
