Problems solved by technology

But even so, display devices still cannot be widely used in teaching or work like projection devices
The reason is that when the projection pen is projected on the display device, the projected light is projected into the display device, and there is interlayer absorption or reflection and reabsorption between the layers inside the display device, so a large part of the light projected into the display device will be lost in the display device. In the display device, causing the audience to lock onto the projected position slower than when using the projection device

Abstract

The invention provides a display device. The display device comprises a liquid crystal box and at least one reflecting medium layer, wherein the at least one reflecting medium layer is used for increasing reflection of projection light projected into the display device so as to reduce loss of the projection light emitted by a projection pen in the display device.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device. Background technique [0002] With the development of display technology, new forms of display devices are continuously developed. Existing display devices can not only be bent, but also have advantages such as high contrast ratio, thinner and thinner. But even so, the display device still cannot be widely used in teaching or work like the projection device. The reason is that when the projection pen is projected on the display device, the projected light is projected into the display device, and there is interlayer absorption or reflection and reabsorption between the layers inside the display device, so a large part of the light projected into the display device will be lost in the display device. In the display device, the speed at which the audience locks on to the projected position is slower than when using the projection device. [0003] ...
