Touch detection method and system of touch screen terminal

Abstract

The invention belongs to the technical field of touch screens, and provides a touch screen terminal as well as a touch detection method and system thereof. The touch detection method comprises the following steps: a, when a detection channel detects that a touch operation is performed on a touch screen, identifying the distribution condition of detection points the data of which changes; and b, according to the identification results obtained in the step a, through combining with the correspondence between the distribution condition of preset detection points the data of which changes and thetouch operation, determining that the area at which the current touch operation aims is a touch screen area or a touch key area, wherein the touch screen area only covers the visible area of the touch screen terminal, and each touch key in the touch key area reuses the detection points in the touch screen. In the invention, because the touch screen area only covers the visible area of the touch screen terminal, the detection resolution of the touch screen at the visible area part can be ensured; and because the touch keys in the touch key area reuse the detection points in the touch screen, the area at which the current touch operation aims can be determined.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a touch detection method and a detection system of a touch screen terminal. Background technique [0002] Touch screen technology provides users with a convenient way of human-computer interaction, and is favored by consumers, so it is increasingly applied to various electronic products. Mainstream smart phone operating systems such as Android and Windows Phone7, in addition to supporting the touch screen, also need the support of 3 to 4 touch buttons, such as figure 1 As shown, area A is the LCD visible area, and area B is the touch button area. The current conventional practice is to expand the touch screen operation area so that it covers the button area, such as figure 2 , that is, the touch screen covers the LCD visible area A and the touch key area B at the same time. The disadvantage of this approach is that in the case of limited detection channels T...
