Displays have image stability for GUI applications

Boasting colour saturation and image stability the TX18D210VM0BAA and TX18D211VM0BAA are two seven-inch Rugged+ TFT displays, released by KOE (Kaohsiung Opto Electronics).

Both display modules feature IPS (in-plane switching) technology, WVGA (800 x 480 pixels) resolution and a 15:9 wide aspect ratio and an extended operating temperature range.

For graphical user interface (GUI) applications, the IPS display technology delivers exceptional colour saturation and image stability, high contrast and deep black levels, says KOE. Viewing angles of up to 170 degrees are supported in all directions (left/right, up/down). The 7.0-inch display features a contrast ratio of 1000:1 and a white LED backlight with a brightness rating of 1200cd/m² and a 50k hour half-brightness lifetime for display images that are exceptionally bright, colourful and accurately reproduced, says KOE.

The optical and environmental specifications of Rugged+ display modules are derived from the standards and quality assurance levels used in automotive grade displays. The two latest Rugged+ display modules have been developed for use under extreme temperature, mechanical shock and vibration environments. The TFT display modules provide reliable operation in extreme temperature environments by supporting an operating temperature range of -40 to +85 degrees C, says KOE.

The TX18D210VM0BAA has a 40-pin CMOS data interface and the TX18D211VM0BAA has a 20-pin LVDS data interface. Each module supports 6-bit RGB data which enables a colour palette of up to 262k colours. Both display modules are compact with mechanical outline dimensions of 167.7 x 109.5 x 9.0mm and have an active display area of 152.4 x 91.44mm. The modules are mechanically and electrically compatible with the existing KOE 7.0-inch TX18D205VM0BAA and TX18D206VM0BAA displays.

The TX18D210VM0BAA and TX18D211VM0BAA both feature a TFT LCD cell which is produced using a low temperature poly-silicon (LTPS) manufacturing process which enables higher brightness, reduced power consumption and reduces internal heat generation due to increased LCD transmittance and an enhanced pixel aperture ratio.

The TX18D210VM0BAA and TX18D211VM0BAA Rugged+ display modules also feature an enhanced cosmetic specification which defines zero bright dot defects i.e. no dead pixels with a bright failure mode.

KOE is committed to ensuring long-term product availability, with continuity of supply essential for many industrial products and equipment. KOE’s new Rugged+ displays can now be sourced and supplied for a minimum period of five years. The TX18D210VM0BAA and TX18D211VM0BAA TFT display modules are available immediately from KOE’s sales channel and distribution partners.
