Touch screen device and mistaken touch preventing identification system and method thereof

Abstract

The invention discloses a mistaken touch preventing identification method. The identification method comprises the steps that when it is detected through screen touching that the distances between one or more zones on the surface and an outside object are smaller than or equal to preset distance threshold values, light sensation values of the zones are detected through screen touching and judged; when it is detected through screen touching that the light sensation values of the zones are smaller than or equal to preset light sensation threshold values, mistaken touch preventing operation is triggered through screen touching. Judgment on touch screen surface light sensation values is added in the mistaken touch preventing identification process, triggering of the mistaken touch preventing operation of a touch screen device is determined when it is detected through screen touching that the light sensation values of the zones are smaller than or equal to the preset light sensation threshold values, the problem that it is erroneously identified through distance sensing detection of a touch screen that the outside object is close to a mobile phone under the situation that the touch screen surface is interfered by oil stains or a distance sensing structure portion deforms slightly, and accordingly false alarm or mistaken touching easily occurred in a bright state of the touch screen is caused is solved, the probability of false alarm or mistaken touching is reduced by judging the light sensation values, and user experience is improved.

Description

technical field [0001] The invention relates to a touch-screen induction recognition technology, in particular to a touch-screen device and its light-sensing-based anti-mistouch recognition system and anti-mistouch recognition method. Background technique [0002] Currently, touch screens are used to operate electronic devices. Users only need to use a stylus to click or directly press with their fingers to easily perform various operations on the screen. With the development of the touch screen, the use of the touch screen is more and more extensive. In the touch screen terminal, the touch screen can realize most of the operation functions, thereby reducing the number of peripheral keys, providing conditions for the mobile terminal system to be reduced, and improving the The integrity of the mobile terminal and its dustproof and waterproof capabilities. [0003] While the touch screen displays its powerful functions, due to the characteristics of its touch operation, it is...

Problems solved by technology

[0011] The existing triggering conditions and judgment methods for this anti-mistouch function will bring about a problem: when the touch screen surface is stained with oil, equipment vibration, partial damage, etc., the judgment of the distance sense structure of the touch screen is slightly deformed. , will lead to when the touch screen is turned on when the screen is on, the distance detection of the touch screen will mistake oil stains or equipment damage for an external object close to the touch screen surface of the mobile phone, and the anti-mistouch function of the mobile device will be triggered by mistake , causing the touch screen of the device to be prone to false alarms and anti-false touches, resulting in reduced user experience
