Abstract

The invention belongs to the field of touch display and specifically relates to a touch display device. The touch display device comprises a display screen, an infrared transmitting tube, an infrared receiving tube and a transparent panel, wherein the transparent panel is arranged on the surface of the display screen, the edges of the transparent panel exceed the display area of the display screen to form protrusion edges, and the infrared transmitting tube and the infrared receiving tube are arranged at the positions above the opposite protrusion edges of the transparent panel, which face one surface of the display screen. The touch display device is provided with the transparent panel to enable the surface of the touch display device to be smooth without raised borders, the infrared transmitting tube and the infrared receiving tube are protected by the transparent panel and are difficult to influenced by factors of human operation, the reliability of touch positioning is improved, and the touch display device is easy to install and operate.

Description

technical field [0001] The invention belongs to the field of touch display, and in particular relates to a touch display device. Background technique [0002] As a new computer input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. [0003] The existing infrared touch positioning method is generally to set an infrared emitting tube and an infrared receiving tube on the edge of the display device. When an object touches the surface of the display device, the touching object will block the light emitted by the infrared emitting tube from entering the corresponding infrared receiving tube. Then the energy received by the corresponding infrared receiving tube is weakened, a reasonable threshold is set, the position of the horizontal and vertical receiving tubes is detected, and the position of the touching object is j...
