Problems solved by technology

[0005] Although the plasma display panel of the display device emits infrared rays, the current plasma display device still needs an additional infrared source and infrared sensor, which must be kept powered on during use to successfully realize the touch panel function
As a result, additional heat is disadvantageously generated, the manufacturing cost of the display panel increases significantly, and unnecessary energy loss occurs over many years

Abstract

A display device has a display panel generating visible light and generating infrared rays; a plurality of detectors detecting a change in an intensity of the infrared rays generated by the display panel; and the plurality of detectors recognizing a touch applied to the display panel in dependence upon the change detected in the intensity of the infrared rays.

Description

technical field [0001] The present invention relates to a display device having a touch screen function, and more particularly, to a display device having a touch screen function by utilizing infrared rays obtained by a light emitting mechanism operated by the display device. Background technique [0002] A display panel having a touch screen function generally refers to a display panel capable of detecting the presence and position of a touch applied by a foreign object within a display area of ​​the display panel. The term "touch" includes physical contact with a display device by a human finger. Currently, display panels with a touch function can be formed in various types, including an infrared type, a resistive film type, a capacitive type, an ultrasonic type, and a pressure sensor type. For a large screen panel, such as a plasma display panel, the display panel is usually formed as an infrared type touch panel, so as to facilitate the realization of a touch screen fun...
