Problems solved by technology

[0004] However, because the AP needs to count the number of frames through software, and the statistical time is too small to occupy too many resources, resulting in increased power consumption, so usually set a larger statistical time, such as 1s
However, a large statistical duration leads to a lag in the adjustment of the refresh rate, and the accuracy is poor

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0029] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0030] Such as figure 1 As shown, under the AP-DDIC-Panel architecture, the AP side first draws and renders layers through the application (Application, App), and then uses SurfaceFlinger to synthesize the drawn layers to obtain image data, and then converts the image data through MIPI The data is sent to display (write) DDIC. The DDIC sto...

Abstract

The embodiment of the invention discloses a frequency conversion display method, a DDIC, a display screen module and a terminal. The method comprises the steps that in response to the received nth frame of image data sent by an AP, a current display scene is determined based on historical image data sending parameters of the AP, and the historical image data sending parameters are obtained through statistics of historical image data receiving conditions by DDIC; a target refresh frequency corresponding to the current display scene is determined, and different display scenes correspond to different refresh frequencies; and a display screen is controlled to display an image based on the target refresh frequency and the nth frame of image data. By adopting the scheme provided by the embodiment of the invention, the statistics of the content updating speed is executed by the DDIC, and the DDIC performs statistics through hardware logic, so that the display scene can be judged frame by frame, and the refresh frequency can be adjusted frame by frame, thereby improving the adjustment timeliness and accuracy of the refresh frequency.

Description

technical field [0001] The embodiments of the present application relate to the field of display technologies, and in particular to a frequency conversion display method, a display driver integrated circuit chip (Display Driver Integrated Circuit, DDIC), a display screen module, and a terminal. Background technique [0002] With the continuous development of display technology, more and more displays that can support high refresh rate display have emerged as the times require. When running high frame rate applications or during sliding operations, by setting the display to high refresh rate mode It can improve the fluency of the picture. [0003] For active-matrix organic light-emitting diode (Active-Matrix Organic Light-EmittingDiode, AMOLED) display, it is limited by the driving architecture of application processor (Application Processor, AP)-DDIC-panel (Panel) and the self-control of AMOLED display. Lighting features, in related technologies, the AP side calculates the ...
