Method and mobile terminal for dynamically adjusting touch screen input detection rate

Abstract

The invention discloses a method for dynamically adjusting touch screen input detection rate and a mobile terminal. The method for dynamically adjusting the touch screen input detection rate particularly comprises the following steps: A, dividing the detection rate of the touch screen which is in a central processing unit (CPU) into a plurality of gears from low to high in advance; B, when the screen is lightened after an operating instruction of a user is received, controlling start of a detection timing device of the touch screen, and detecting input of the touch screen every other presetting time according to the default detection rate; and C, recording the latest N times of detection results, analyzing and judging detection results, and when the input of the touch screen are detected for continuous N times, controlling the detection rate of the touch screen to select a higher gear of the detection rate; and when the input of the touch screen are not detected for continuous N times, controlling the detection rate of the touch screen to select a lower gear of the detection rate, wherein the N is a natural number which is larger than 0. The method for dynamically adjusting the touch screen input detection rate and the mobile terminal have the advantages of being capable of improving detection sensitivity of the touch screen and reducing energy consumption.

Description

Technical field [0001] The present invention relates to the field of mobile terminals, and in particular to a mobile terminal and method for dynamically adjusting the rate of a CPU to detect a touch screen according to the speed of a user's input on a touch screen. Background technique [0002] Currently in smart phones, most of the user's input operations are achieved through touch screens, but smart phones on the market now have powerful functions. Users use smart phones to make calls, QQ chat, and play games. Obviously, the user's touch screen input rate often changes when using a smart phone. For example, the touch screen input rate is zero when making a call, while the touch screen input rate is fast and slow during QQ chat, and the touch screen input may remain constant when playing games. Faster rate. However, in the existing technical implementation, the position of the user touch detected by the touch screen input is read at intervals (for example, 50 ms), and the CPU i...

Problems solved by technology

[0003] The touch screen detection in the prior art all uses a fixed rate, and the fixed rate touch screen input detection method has the following defects when detecting different applications operated by the user: when the user touches the touch screen at a low rate, due to the detection of user touch screen input at the mobile The speed is too fast, which makes some detections actually useless, and consumes system resources in this case; when the user touches the touch screen at a high speed, the speed of detecting the user's touch screen input on the mobile phone is too slow, resulting in some users' input failing. Detected, making the user feel that the touch screen is not working and the response is slow
