Problems solved by technology

When the synchronization signal arrives (from low level to high level), the control pulse is forcibly pulled to high level, and the drive module generates control pulse 1 within the refresh period N+2. At this time, within the refresh period N+2 The combination of control pulse 1 and pulse X makes the duty cycle of the control pulse larger, causing the display to brighten suddenly

Abstract

The invention relates to a display control method and device, a driving module and electronic equipment. The display control method comprises the following steps: acquiring a delay instruction from a processor; the delay instruction comprises delay duration required for displaying the frame of image; determining a plurality of control pulses required for displaying the frame of image according to the delay duration, wherein the duty ratios of the plurality of control pulses are the same; and when a synchronizing signal is received, each control pulse in the plurality of control pulses is generated in sequence, and the control pulses are used for controlling the AMOLED display screen to carry out dimming display. According to the embodiment of the invention, the duty ratio of each control pulse in one refresh cycle can be the same, the display of the AMOLED display screen can be kept unchanged, the situation of display picture jitter is avoided, and the watching experience is improved.

Description

Technical field [0001] The present disclosure relates to display technology, and particularly relates to a control method and apparatus driving module, the electronic device displays. Background technique [0002] Currently, electronic devices will use AMOLED display screen, when the electronic device using the AMOLED display, in low light, AMOLED display using pulse-width modulation (PWM) dimming, the dimming mode for each frame image generation integer number (e.g., four) of control pulses (EM), and is adjusted by controlling duty of each pulse of the backlit display. [0003] Combine figure 1 Structure of the electronic device shown, a processor (AP) the processing of information, often encounter a large amount of data, the case can not be processed within one frame image display time. Thus, in the related art, the processor can continue to process and transmit the information within a next frame time. Since the processor of two successive frames of the same information is tra...
