Description

Electronic screen refresh rate intelligent control method capable of achieving energy saving, electricity saving and image quality smoothness Technical Field The invention relates to the technical field of electronic display, in particular to an intelligent control method for an electronic screen refresh rate, which is capable of achieving energy saving, electricity saving and smooth image quality. Background With the popularity of high refresh rate (e.g., 90hz,120hz,144 hz) screens on mobile devices and displays, users are also challenged to shorten the endurance time while enjoying a very smooth visual experience. The screen is used as a large power consumption user of the whole machine, and the refresh rate and the power consumption of the screen basically have a linear positive correlation. The existing electronic screen refresh rate adjustment technology mainly adopts two strategies, namely, static configuration based on application scenes, for example, a system locks 60Hz for 'gallery' and 'reading' applications and opens 120Hz for 'game' applications. This approach is extensive and inflexible and cannot cope with dynamic changes of different content within the same application (e.g. sliding page turning and stationary reading within the reading App). And secondly, based on dynamic adjustment of frame content variation, for example, when continuous multi-frame content output by the GPU is completely static, the refresh rate is reduced to a very low level (such as 1 Hz). However, the current technology has a "reaction hysteresis" problem that when a user suddenly starts to interact (such as fast sliding), the system needs to wake up from a low refresh rate state and climb to a high refresh rate, and this process can generate a perceptible click or smear, which breaks the fluent experience. The root cause is that the prior art only passively responds to content changes that have occurred, and cannot actively predict the user's interaction intent. Based on this, there is a need for improvements to existing electronic screen refresh rate control methods to improve the fluent visual experience. Disclosure of Invention Compared with the prior art, the application aims to design the method for intelligently adjusting the refresh rate of the display equipment according to the dynamic complexity of the electronic screen content and the prediction of the user interaction behavior, and solve the technical defects of the prior art. In order to achieve the above purpose, the present invention provides the following technical solutions: An intelligent control method for the refresh rate of an electronic screen, which takes into account energy and electricity saving and smooth image quality, comprises the following steps: step S1, monitoring continuous frame images in real time and calculating the inter-frame difference degree of the continuous frame images; s2, monitoring and analyzing an input event stream of a user in real time, and predicting the triggering high-intensity dynamic interaction probability in future delta t time of the user; and S3, updating the refreshing frequency of the electronic screen according to the inter-frame difference degree and the high-intensity dynamic interaction probability, and updating the refreshing frequency to the lowest gear when the inter-frame difference degree is lower than a low dynamic threshold value and the high-intensity dynamic interaction probability is lower than a low interaction probability threshold value. The technical scheme has the following technical effects: Through the technical scheme, the application provides the intelligent control method for the refresh rate of the electronic screen, which has the advantages of energy saving, electricity saving and smooth image quality. According to the method, by fusing a 'real-time content analysis' and a 'prospective interaction prediction' double engine, accurate and advanced control of refresh rate switching time and amplitude is realized, so that the average refresh rate is reduced to the minimum on the premise that smooth response can be obtained for any sudden interaction, and the unification of energy conservation and smoothness is achieved. As an improvement on the intelligent control method for the refresh rate of the electronic screen, which takes energy saving and electricity saving into consideration and smooth image quality, in the step S3, the refresh frequency gear of the electronic screen comprises a high refresh gear, a medium refresh gear and a low refresh gear; when the inter-frame difference is higher than the high dynamic threshold, updating the refresh frequency into a high refresh gear; when the inter-frame difference is lower than the low dynamic threshold and the high-strength dynamic interaction probability is lower than the low interaction probability threshold, updating the refresh frequency to be a low refresh gear; and when the inter-frame difference degree is lower than the low dynamic
