Abstract

The present application discloses a display device and a touch controller. The display device includes: a protective screen, a display panel, a photosensitive element, and a light-collecting element. The protective screen is arranged on the light-emitting surface of the display device, and the photosensitive element It is arranged between the display panel and the protective screen; the photosensitive element includes a photosensitive surface that receives light; Shorter, the number of glass layers or the number of film structures that the finger reflected light needs to pass through before the measuring light reaches the photosensitive element is reduced, so the possibility that the finger reflected light is received by the photosensitive element increases, and the photosensitive accuracy of the photosensitive element is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a touch controller. Background technique [0002] With the development of multimedia technology, touch technology has become a hot technology in human-computer interaction today. Optical touch technology is another mainstream touch technology in addition to touch technologies such as resistance and capacitance. Optical sensors are sensitive to detailed movements. Quick response can be applied to conference venues, commercial exhibition venues, education and training venues, exhibitions, financial industries, and military industries. The distance of optical touch is usually reflected by using a light source to irradiate the finger, which is received by the sensing element to identify the specific position of the touch. [0003] However, under normal circumstances, due to the long path of the reflected light entering the photosensitive element, ther...
