Problems solved by technology

[0006] However, the control chip of the resistive touch screen does not have this function. It usually only samples the level of the X and Y axes of the touch point. The location range, determine the corresponding operation
Therefore, although the cost of the resistive touch screen is relatively low, its corresponding functions are relatively small, and it is generally only used as a simple input device.

Abstract

The invention discloses a method and a device for controlling a move event on a resistive touch screen, which are used for realizing inertial sliding on the resistive touch screen and expanding the application range of the resistive touch screen. The method comprises the following steps of: acquiring first information of a starting point of the move event and second information of an ending point of the move event; determining a moving speed of a target project in the move event according to the first information and the second information; acquiring a desired distance corresponding to the determined moving speed according to the proportional relation between the moving speed and the desired distance of the inertial sliding; and moving the target project according to the desired distance.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method and device for controlling movement events on a resistive touch screen. Background technique [0002] At present, the application of touch screen technology is becoming more and more extensive, and its application functions are becoming more and more powerful. "Inertial sliding" is undoubtedly one of the most dazzling functions. [0003] "Inertial sliding" means that the hand or object slides a certain distance on the touch screen, and the corresponding target item on the LCD also slides. When the hand or object leaves the touch screen, the system will continue to scroll the target item by simulating the inertial effect in real life. The effect of stopping slowly. [0004] see figure 1 , the touch-type mobile terminal includes: a touch screen 100 , a touch screen control chip 200 , a driver 300 and an upper controller 400 . Wherein, the touch screen 100 may be a...
