Tft Lcd Driver Circuit

We developed an a si tft lcd panel with integrated gate driver circuit using a standard 5 mask process.

Tft lcd driver circuit.

The output voltage of proposed gate driver circuit can be estimated as 40v by using cadence microwind simulators. The ili9341 tft display board which is shown in the circuit diagram above has 14 pins the first 9 pins are for the display and the other 5 pins are for the touch module. Gan and kuan wen chou journal ieee transactions on electron devices year 2012 volume 59 pages 1410 1415. Introduction with the rapid evolution of liquid crystal display lcd television tv there is a large demand for developing high resolution high co lor depth driver integrated circuits ics 1 3.

The driver circuits of lcd are composed of two parts the gate driver and the data driver. To minimize the effect of the a si tft current and lc s capacitance variation with temperature we developed a new a si tft circuit structure and minimized coupling capacitance by changing vertical architecture above gate driver circuit. Interfacing arduino with ili9341 tft display circuit.
