Abstract

The invention discloses a display panel driving circuit, a driving method of a display panel and a displayer, the display panel driving circuit comprises a driving signal access end, a conversion circuit, an integrating circuit and a main control chip, the driving signal access end accesses a display panel driving signal, and the conversion circuit is connected with the integrating circuit. The conversion circuit converts a display panel driving signal into a PWM signal with a corresponding duty ratio, and the integral circuit performs integral processing on the PWM signal into an analog level signal with a corresponding voltage value. And the main control chip synchronizes the duty ratio of the PWM signal according to the voltage value of the analog level signal, and drives the display panel to work according to the duty ratio of the PWM signal and a preset frequency. According to the scheme, the technical problem of flickering of the LVDS display panel is solved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel driving circuit, a display panel driving method and a display panel. Background technique [0002] At present, the display panel is divided into LVDS (Low-Voltage Differential Signaling) display panel and EDP (embedded DisplayPort) display panel. Among them, the driving process of the LVDS display panel is: LVDS signal is converted into PWM (Pulse Width Modulation, Modulation) signal, the PWM signal drives the display panel to light up. At this time, due to the low frequency of the PWM signal converted by the LVDS signal, the duty cycle of the PWM is small when the display panel is in low brightness, and the display panel will flicker when the frequency is low. Phenomena that affect user experience. Contents of the invention [0003] The main purpose of the present invention is to propose a method for driving a display panel, aiming at solving th...
