TFT display modules suitable for portable systems

Hitachi Display Products has released a trio of compact, high-performance TFT LCD modules that are suitable for portable and hand-held applications.

The 2.4, 3.5 and 4.3in TFT display modules measure 41.9 (w) x 61.5 (h) x 2.6mm (d), making the 2.4in QVGA (240 x 320 pixels) TX06D126VM0AAA the smallest TFT display module currently available from Hitachi.

Hitachi's IPS (in-plane switching) technology and a white LED backlight ensure that high optical performance is achieved from all viewing angles.

To aid the design in process, the 2.4in TFT display also features an integrated 80 series CPU interface and display RAM.

The 3.5in QVGA (240 x 320 pixels) TX09D30VM1CDA is the latest addition to Hitachi's established 3.5in TFT line up.

The portrait display has mechanical dimensions of 64 (w) x 86 (h) x 6.7mm (d) and a 40-pin 18-bit CMOS RGB interface supporting a colour palette of up to 262,000 colours.

Other integrated features include an LED backlight controller and onboard power supply circuitry, which enables a single 3.3V input to be used.

The TX09D30VM1CDA weighs 40g.

The TX11D04VM2AAA is a 4.3in WQVGA (480 x 272 pixels) display with mechanical dimensions 105.5 (w) x 67.2 (h) x 2.9mm (d).

The landscape display has a 40-pin 24-bit CMOS RGB interface, allowing up to 16.7M colours to be displayed.

A contrast ratio of 550:1 and a brightness of 350cd/m ensure that display images are clear, bright and well defined.

Low-power applications are ideally suited as the TX11D04VM2AAA LCD has a power consumption of 49mW.

All three display modules employ chip on glass (COG) construction, which ensures compact mechanical dimensions and robust, reliable operation.

Low-power white LED backlights feature throughout, providing high brightness and display uniformity characteristics.

All three displays feature an operating temperature range of -20 to 70C.
