HX8346-A(T)240RGBx320 dots, 262K color TFT controller driverPower-on sequenceDATA SHEET V01The FR-mode starts automatically after the power supply is switched on and a resetpulse is applied to the Reset-pin, if the BURN-pin is set to logical high. In case ofseparate supply pins for the analogue supply and digital supply, both supply pins willbe connected together, if the driver specification allows it. Otherwise, each supplyvoltage will be switched on separately according to the requested power-on sequence.The BURN-pin and all other digital I/F pins, which will be set to logic high during thefree running mode, can be switched to logic high together with the digital supply pin.The FR-mode will be restarted if the reset pulse is applied a second time.

The black to white ratio shall be 50%/50%. The time of the black and whitepattern shall be around 1 second in order to avoid a too long waiting time to verify thatthe FR-mode is functioning properly. The display is switched to a static black patternafter the alternating mode is finished. Thus, most efficient burn-in stress is ensured.The display shall work in idle-mode. There is no special restriction for the framefrequency. It can be between 5 and 100Hz.
