Clear monochrome display, indoors and out

Industrial LCD manufacturer KOE has introduced the TX14D201MM2BAA, a 5.7inch monochrome TFT display module. It features QVGA resolution with a 4:3 aspect ratio, excellent optical performance and a high brightness LED backlight for use in electric vehicle charging stations, ticketing systems, vending machines and process instrumentation.

The monochrome TFT display produces images that are legible and clear in both indoor and outdoor applications due to its contrast ratio of 1200:1 and a LED backlight with a brightness rating of 1500cd/m². The LED backlight is said to have a specified 40K hour half brightness lifetime. The display also exhibits some reflective properties, due to the absence of a colour filter, which enables a reduction in power consumption if the backlight is dimmed.

Monochrome TFT is claimed to provide operating stability over a wide operating temperature range and requires no additional temperature compensation circuitry when compared with Monochrome STN technology.

The display module has mechanical outline dimensions of 131 x 104.2 x 7.8mm, an active display area of 115.2 x 86.4mm and weighs 120g. A 40-pin data connector supports an industry standard 8080-series MPU 8-bit parallel interface.
