TFT Controller IC Specifications.

Display Interfacing Support

TFT Controller IC's are critical components in the design manufacture of a TFT Module, and consist of most commonly a COG IC embedded at the bottom edge of the glass, often obscured by a protective mask.


The TFT IC receives image data and delivers precise analog voltages or currents to activate the pixels on the display.


When voltage is applied to the liquid crystal within each pixel cell, the liquid crystal is bent, thereby changing the intensity of light that passes through each individual pixel. Combined with the colour filter on the front glass substrate, each pixel generates its own colours which, together with other pixels, make up the whole image at the surface of the module.

Modern IC's are small form factor, and support multiple interface modes, which are often register selectable. You may find that one TFT design can support RGB, or MPU depending upon the pin configuration.  Halo's team have catalogued a number of relevant TFT IC's to assist Design Engineers when selefcting and working with our TFT technology. Below you can access the specific PDF's.
