For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] Most rearview mirror surfaces cannot hide the LOGO, buttons and mirror display viewing area when the backlight is turned off.

[0027] In view of the above problems, the embodiments of the present application provide a mirror touch display module and a rearview mirror, which can hide the LOGO, buttons and the viewing area of ​​the mirror display screen when the backlight is turned off.

[0028] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0029] See also Figures 1 to 4 A mirror touch display module includes: a cover plate 100, a liquid crystal module 200 and a backlight module 300, the cover plate 100 includes a cover plate body 110, a semi-transmissive and semi-reflective film layer 120, a first ink layer 130 and a second ink layer 140, the first side of the semi-transmissive and semi-reflective film layer 120 is arranged on the cover plate body 110, the first ink layer 130 and the second ink layer 140 are respectively arranged on the second side of the semi-transmissive and semi-reflective film layer 120, a display area 150 is arranged between the first ink layer 130 and the second ink layer 140, a first avoidance area 131 is opened on the first ink layer 130, and a second avoidance area 141 is opened on the second ink layer 140; the liquid crystal module 200 is arranged on the display area 150; the backlight module 300 includes a light source 310, and the light source 310 is arranged on the liquid crystal module 200.

[0030] It should be noted that the semi-transparent and semi-reflective film layer 120 has a preset ratio of transmittance and reflectance. The transmittance in this application refers to the transmittance of light, that is, the ratio of the luminous flux after passing through an object to the incident luminous flux, and the reflectance refers to the reflectance of light, that is, the ratio of the reflected luminous flux to the incident luminous flux. The ratio of transmittance and reflectance of the semi-transparent and semi-reflective film layer 120 is 50:50. Furthermore, the first avoidance area 131 and the second avoidance area 141 are LOGO and buttons formed by silk screen printing. In this way, when the light source is not lit, the LOGO, buttons and display area 150 can achieve the effect of a full mirror; when the light source is lit, the LOGO and buttons can also be clearly displayed.

[0031] See also Figure 3 In one embodiment, the length of the semi-transmissive and semi-reflective film layer 120 is the same as the length of the cover body 110 .

[0032] It should be noted that the semi-transparent and semi-reflective film layer 120 is fully covered on the cover body 110 to achieve the best display effect. Specifically, the semi-transparent and semi-reflective film layer 120 is actually a mirror silver coating layer, which uses a magnetic field to excite the metal equipment, releases the metal ions and deposits them on the surface of the substrate. When preparing high-purity silver film, magnetron sputtering is usually used. By adjusting the flow rate of the auxiliary gas and the purity of the target material, a high-purity mirror silver film can be obtained. Stainless steel or aluminum is used for deposition. As deposited mirror silver, it has better corrosion resistance and a milder appearance. It can replace metallic silver at a lower cost.

[0033] See also Figure 4 In one embodiment, the light source 310 is provided with a first light emitting area 311, a second light emitting area, and a third light emitting area 312. The first light emitting area 311 is parallel to the first ink layer 130, the second light emitting area is parallel to the display area 150, and the third light emitting area 312 is parallel to the second ink layer 140. Specifically, the first air avoidance area 131 is parallel to the first light emitting area 311. Specifically, the second air avoidance area 141 is parallel to the third light emitting area 312.

[0034] It should be noted that the light source 310 of the present application is longer than the conventional one, and is almost flush with the cover body 110. In the conventional method, the display screen is enlarged in order to add the LOGO and buttons, which will increase the cost. Furthermore, the first light-emitting area 311 and the third light-emitting area 312 are used to illuminate the LOGO and buttons, and the second light-emitting area is used to provide light for the liquid crystal module 200.

[0035] See also Figure 2In one embodiment, the liquid crystal module 200 includes an optical adhesive layer 210, and the optical adhesive layer 210 is disposed on the display area 150. Specifically, the liquid crystal module 200 also includes a bracket 220 and a liquid crystal layer 230, the bracket 220 is disposed on the optical adhesive layer 210, and the liquid crystal layer 230 is disposed in the bracket 220. Specifically, the liquid crystal module 200 also includes a foam 240, and the foam 240 is disposed on the liquid crystal layer 230. Specifically, the liquid crystal layer 230 includes a first glass plate 231 and a second glass plate 232, and the first glass plate 231 is disposed on the second glass plate 232.

[0036] It should be noted that the foam 240 serves to fix the liquid crystal layer 230 , and the foam 240 is located on the second glass plate 232 .
