Embodiment approach

[0035] In one embodiment of the present invention, preferably the photosensitive film 3 is a two-dimensional optical network structure through which backlight can pass, such as figure 2 As shown, each node of the mesh structure is a touch coordinate, and the nodes therein can be triangle points, square points or points of other shapes, and are preferably round points in this solution. The photosensitive film 3 is designed as a mesh structure or a sieve structure, the purpose is to ensure that the backlight can pass through the photosensitive film 3 without reducing the brightness, that is, it will not affect the brightness of the display. At the same time, the two-dimensional planar network structure corresponds to specific X coordinates and Y coordinates, so that the touch coordinates of the finger can be directly located and the touch accuracy can be improved.

[0036] The photosensitive film 3 in this solution has a minimum touch accuracy of 4096×4096.

[0037] In one emb...

Abstract

The invention provides a displayer. The manufacturing cost of the displayer is low, and the displayer is not easily interfered by light from the external environment, is excellent in touch effect andconsists of a backlight module and a liquid crystal module; a first polarizing film is arranged between the backlight module and the liquid crustal module, and a second polarizing film is arranged onthe outer side of the liquid crystal module. A color filter is arranged between the liquid crystal module and the second polarizing film; a photosensitive film including a light receiving surface anda backlight surface is arranged between the liquid crystal module and the first polarizing film; the light receiving surface generates electrical signals under illumination, and the backlight surfacedoes not generate electrical signals under illumination. The light receiving surface is close to one side of the liquid crystal module.

Description

technical field [0001] The invention relates to the technical field of liquid crystals, in particular to a display capable of effectively reducing external ambient light interference. Background technique [0002] A liquid crystal display is a flat and ultra-thin display device, which has been widely used in various electronic products, especially in products such as computers, televisions, and mobile phones. At present, the touch screen has become an important medium component of human-computer interaction due to its convenient touch method, and has been widely used in various electronic products, especially in display products. [0003] In an existing display with a touch function, a touch panel is usually installed on the assembled display panel. This method of post-installing the touch panel will not only increase the cost, weight and thickness of the display, but also affect the display brightness of the display and affect the user's vision because the light transmitta...
