The technical solutions of the present invention and how the technical solutions of the present application solve the above technical problems will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic structural diagram of an electronic device 10 according to an embodiment of the present invention. 1 is taken as an example, but it is not intended to limit the invention. The electronic device 10 can be an electronic device 10 with a fingerprint recognition function, such as a mobile phone or a tablet computer. For details, please refer to FIG. 1 , the electronic device 10 can include:

The touch screen TP cover 101 and the liquid crystal display LCD 102.

The TP cover 101 and the LCD 102 are stacked, and the TP cover 101 is disposed above the LCD 102. The TP cover 101 is provided with a fingerprint module area, the fingerprint module area is provided with a fingerprint module 1011, and the LCD 102 includes an LCD driver. There is an overlap area between the chip IC area 1021 and the display area 1022, the fingerprint module area, and the LCD drive IC area 1021.

The TP cover 101 is a cover plate disposed at the outermost layer of the electronic device 10 for protecting the integrity of the LCD 102. Generally, the material of the TP cover 101 is made of glass, that is, a TP glass cover. In order to improve the strength of the TP glass cover, the glass used in the TP glass cover is obtained by chemically adding the original glass, that is, immersing the glass in a high-temperature molten salt at a certain temperature, and alkali metal in the glass. The alkali metal ions in the ions and the molten salt exchange with each other to form a compressive stress layer of a certain thickness on the surface (edge) of the glass, and the compressive stress layer makes the crack difficult to diffuse, thereby improving the strength of the glass, thereby passing the TP glass cover. The board protects the LCD 102.

The liquid crystal display LCD 102 is composed of a certain number of color or black and white pixels and is placed in front of the light source or the reflecting surface. Its working principle: Liquid crystal is a kind of special substance between solid and liquid. It is an organic compound. It is liquid in normal state, but its molecular arrangement is as regular as solid crystal, so it is called liquid crystal. Another special property is that if an electric field is applied to the liquid crystal, its molecular alignment will be changed. If it is combined with a polarizer, it will have the effect of blocking the passage of light (the light can pass through when no electric field is applied). ), if you match the color filter, change the amount of voltage applied to the liquid crystal, you can change the amount of light transmission of a certain color. In other words, changing the voltage across the liquid crystal can change its transmittance, thus showing Different images.
