Abstract: The present application provides a screen touch point positioning method, a device, and an electronic apparatus. The screen touch point positioning method includes: sequentially scanning each of the point positions on a screen to obtain each of the touch feature value of the point position, determining an end point coordinate; then aggregating adjacent sensed point positions of each row to touch line segments; further determining the line segment coordinates of the touch line segments; aggregating each of the touch line segments to obtain an aggregation touch region; finally determining a coordinate of a screen touch point. The embodiment of the present application solves an issue of a conventional screen touch point positioning method being complicated and time consuming.

Abstract: A backlight driving method and a display panel are provided. The backlight driving method provided by the present application uses pulse width modulation technology to modulate a low-level pulse width of a scan signal. By increasing a low-level pulse width to increase the pulse period, a number of high-level pulses is reduced, thereby reducing a high-level pulse time. Therefore, a time for a TFT to receive a high-level voltage is also reduced, thereby improving a stability of the TFT and also improving a problem of a threshold voltage drift of the TFT.
