Abstract

The invention discloses an infrared touch screen and a detection method thereof. An infrared emission tube array of the infrared touch screen consists of a plurality of emission units comprising infrared emission tubes; an infrared receiving tube array consists of a plurality of receiving units comprising infrared receiving tubes; the number of the emission units and the number of the receiving units included in the infrared emission tube array and the infrared receiving tube array which are arranged in the same direction are the same and the emission units and the receiving units are in one-to-one correspondence; the number of the infrared emission tubes and the number of the infrared receiving tubes included in each group of emission units and each group of receiving units which are arranged in the same direction are the same and the infrared emission tubes and the infrared receiving tubes are in one-to-one correspondence; the number of gating circuits is equal to the sum of the number of the receiving units and the number of the emission units; and each gating circuit is connected with one receiving unit or one emission unit. The infrared touch screen has the advantage of high response speed; and the detection method of the infrared touch screen has the advantage of short detection period.

Description

technical field [0001] The invention relates to a touch screen and a detection method thereof, in particular to an infrared touch screen applied in the game industry and a detection method thereof. Background technique [0002] As an intuitive and easy-to-operate human-computer interaction device, the touch screen is applied to more and more fields, and the game industry is one of them. In the field of game applications, the application of touch screens increases the diversity of games, and also puts forward corresponding requirements for the performance of touch screens: 1. The response speed of touch screens is required to be fast enough to enhance the experience of game players; 2. The performance of touch screens is required The cost is low, which is conducive to mass production. However, either the response speed of existing game touch screens does not meet the requirements or the cost of manufacture is too high, which restricts the development of game infrared touch s...
