Midas Character OLED Displays, COB This series of Organic Light Emitting Displays (OLEDs), from Midas Displays, are chip-on-board (COB) character format OLEDs with passive technology. These easy-to-use OLED devices are made up of a PCB mounted with both the driver and the display. As an ideal, drop-in replacement for standard LCD character modules, the Midas COB OLEDs have a comparable footprint to LCD character display common board sizes. With their high brightness, high contrast and fast refresh levels, the graphic COB OLED displays are a seamless upgrade from standard LCD modules. The Midas OLEDs are available in a range of colour options including yellow, green, blue red and white, and are ideal for applications where a specific colour of display is required on a black background appearance (negative mode).

The Midas character COB OLEDs also boast an extremely wide viewing angle of up to 175°, creating a solution for applications where it is necessary for the display to be readable from all angles. These OLED devices also offer lower energy consumption than traditional LCD modules and a wide operating temperature range. Their low profile display height and interface comparable with HD44780 means the Midas COB OLEDs are suitable for a variety of traditional applications. Available in 8 to 40 character options on 2 lines, Midas’ OLED displays offer 4 font sets on 1 device including English, Japanese, Western European and Cyrillic character fonts. The Midas COB OLED devices have a 5x8 dot matrix characters with a height of 5.50 to 5.57mm.
