Compact colour display replaces monochrome display – even in sunlight

12 SEPTEMBER 2019

The chromatic IPS-TFT panel EA TFT020-23 with a screen diagonal of 2 inches provides an extremely fine resolution, wide viewing angles and excellent sunlight readability. Its versatile, standardized interfaces facilitate the further development of products using monochrome displays.

Electronic Assembly designed the 2-inch TFT020-23 as a full-color alternative to monochrome graphic displays, which are widely used in handheld devices. Despite its compact size of only 36 x 52 mm, it features a very fine resolution of 240 x 320 pixels. With a brightness of 1,000 cd/m² it delivers brilliant images in the office, production or operating room, even in bright sunlight. Thanks to the IPS technology, the crisp, sharp contrast is preserved over a wide viewing angle of 160° and the colours remain unchanged, even at the most oblique viewing angle.

One connector combines all control lines of the display, the backlight and even the optional touch panel with 39 pins at 0.5 mm pitch. The version with capacitive touch surface including I²C controller is called EA TFT020-23AITC. This version measures 43 x 65 mm, the touch panel (PCAP) is optically bonded for a clear and low-reflection display.

The TFT display runs directly at 3.3 V and requires no additional auxiliary voltage. The SPI interface guarantees simple control with all common microcontrollers due to integrated display RAM. The same display can also be addressed via a classic RGB interface. Last but not least, connection to an 8- or 16-bit data bus is also possible.

Since both models were designed as handheld displays for heavy-duty outdoor use, they are able to cope with ambient temperatures of -20° C to +70° C. Their service life amounts to 50,000 hours.

Electronic Assembly does not stipulate a minimum order quantity for this product either and already delivers one piece of the TFT020-23 ex stock. With the excellent quality of its products, comprehensive support and at least ten years of stock availability, the manufacturer supports the implementation of long-term product lines.
