摘要： Embodiments of this application provide a display driver, a control method, a display control circuit system, and an electronic device, and relate to the field of electronics and communications technologies, to reduce, in a command mode, a probability that a screen stalling phenomenon occurs during display of a dynamic image and reduce power consumption of a display. A timing control unit in the display driver sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an N th frame of display data within a preset time, where the S second pulses of the tearing effect signal are used to prolong duration of the N th frame by a second preset time T2, and indicate a host to output the generated N th frame of display data in an (N+1) th frame based on an S th second pulse of the tearing effect signal. The processing unit receives the N th frame of display data in the (N+1) th frame, and controls, based on the N th frame of display data, the display to display an N th frame of image.

摘要： An electronic device and a method for displaying an image in a multi display drive circuit system are provided. A host controller (101) splits a to-be-displayed image into at least two sub images, where each sub image and an adjacent sub image thereof include at least one column of overlapping image pixels. The host controller (101) sends the at least two sub images to at least two display drive circuits (102 and 103), so that the at least two display drive circuits (102 and 103) can jointly drive a display screen (104) to display the to-be-displayed image in an SPR manner. Alternatively, the host controller (101) outputs at least two sub images rendered in an SPR pixel format to at least two display drive circuits (102 and 103), so that the at least two display drive circuits (102 and 103) can jointly drive a display screen (104) to display the to-be-displayed image in an SPR manner. The multiple display drive circuits (102 and 103) do not need to establish a data channel to share pixel data, thereby avoiding problems such as EPC area increase, EMI, and ESD.

A display screen includes a first display area and a second display area, a camera component is disposed under the first display area, and light transmittance of the first display area is higher than light transmittance of the second display area. The adjustment method includes: collecting present ambient illuminance on a terminal (S601); and when the ambient illuminance is lower than an ambient illuminance threshold, adjusting, based on a first ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the first display area to first luminance, and adjusting, based on a second ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the second display area to second luminance, where the first luminance is approximately equal to the second luminance (S602). The first ambient light adaptation adjustment curve indicates a mapping relationship between ambient illuminance and the luminance corresponding to the grayscale 255 of the first display area; and the second ambient light adaptation adjustment curve indicates a mapping relationship between ambient illuminance and the luminance corresponding to the grayscale 255 of the second display area. Ambient light adaptation adjustment curves of multiple levels are set to adjust the luminance corresponding to the grayscale 255 of the first display area and the luminance corresponding to the grayscale 255 of the second display area respectively, so that luminance of the first display area is controlled to be approximately equal to luminance of the second display area. In this way, uneven luminance of the first display area and the second display area can be avoided, and a display effect of the terminal screen can be improved.
