That is, the control of the third MOS transistor Q3 is very low, the first MOS transistor Q1 is operated in a conducting state, the power management module PM10 LDO1 outputs VCC1 power, and the power is output to the positive power VP of the color-changing film through the first MOS transistor Q1. When the INT signal is at a low level, that is, the control of the fourth MOS transistor Q4 is at a very low level, the fourth MOS transistor Q4 operates in an off state. The color-changing film VP is connected with the VCC1 power supply to supply power to display a transparent state.

According to the touch control color-changing film display method, a user performs touch control operation on a touch control panel, and the touch control panel responds to the touch control operation and outputs different level signals; the switch control circuit receives the level signal and further controls the output of different voltages to the color-changing film; the color-changing film presents different states according to different input voltages; according to the display control method and device, the display state of the color-changing film is changed by flashing of different frequencies of the color-changing film according to the touch control frequency of the touch control display screen, and the display effect is improved.
