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

[0029] First, see Figure 1-2 , the embodiment of the utility model provides a cover plate, comprising: a cover glass 10, a first ink layer 20, a second ink layer 30 and a third ink layer 40;

[0030] The first ink layer 20 is disposed on the cover glass 10. The first ink layer 20 is common ink. The first ink layer 20 includes an ink portion 21 and a pattern hollow groove 22. The pattern hollow groove 22 runs through the first ink layer 20.

[0031] The second ink layer 30 is disposed in the pattern hollow groove 22, and the second ink layer 30 is a color-changing ink, and the initial color of the color-changing ink is the same as the color of the first ink layer;

[0032] The third ink layer 40 is also the color-changing ink, and the third ink layer 40 is disposed on the ink portion 21 of the first ink layer 20 .

[0033] For a display device, it usually includes a cover plate and a housing. The first ink layer is preferably the same color as the housing or a mirror color. In the embodiment of the utility model, white ink is used as an example. The screen printing screen of the first ink layer 20 is designed as follows: the position of the pattern hollow groove 22 is designed to be not opened, so after the first ink layer 20 is screen-printed, there is no ink at the position of the pattern hollow groove 22, so that the second ink layer 30 can be screen-printed in the pattern hollow groove 22. The design of the pattern hollow groove can be a key pattern, Arabic numerals, a personalized pattern, etc.

[0034] The initial color of the color-changing ink of the second ink layer 30 is the same as the color of the first ink layer. In the embodiment of the utility model, the initial color of the color-changing ink is the same as the color of the first ink layer, which is white. The color-changing ink can change to other colors, such as yellow, after the color change. The screen printing plate of the second ink layer 30 is designed to be screen-printed only at the position of the pattern hollow groove 22, so that the second ink layer 30 is filled in the pattern hollow groove 22.

[0035] Since the third ink layer 40 is the same color as the first ink layer 20 and is above the ink portion 21 of the first ink layer 20, the third ink layer cannot be seen through the cover glass, which can solve the problem of the frame printing of the third ink layer being seen when there is strong light from the front. When necessary, the third ink layer can be changed in color through photosensitivity, etc., so that information of the third ink layer, such as the equipment production date and equipment model information, can be seen.

[0036] The technical solution of the embodiment of the utility model can achieve effects such as hiding icons, button patterns, character marks and adjustable numbers by setting a multi-level first ink layer, a second ink layer and a third ink layer. The second ink layer and the third ink layer use color-changing ink. While solving the problem of cover plate character mark frame printing, the effect of a traditional segment-type LCD display is achieved by partitioning the color of the color-changing ink, which greatly saves costs. Different combinations of icons or buttons can be achieved by utilizing whether different graphics change color or not, thereby enhancing product diversity.

[0037] As a preferred embodiment of the present invention, the color-changing ink is a photosensitive color-changing ink, which changes color under ultraviolet light. For example, the initial color of the color-changing ink is white. Under ultraviolet light, LED light with ultraviolet band, or sunlight, the color-changing ink changes from white to yellow or other colors. When the ultraviolet light, LED light with ultraviolet band, or sunlight is lost, the color-changing ink returns to the initial color. Figure 3-4The cover plate of the utility model can illuminate the second ink layer at different positions through the partition switch of the LED lamp, so as to achieve different display effects. Figure 3 The dotted line in the figure is the second ink layer 30. When there is no light, the entire cover plate displays the same color, such as white.

[0038] As a preferred embodiment of the present invention, the third ink layer is a silk-screen layer containing a character mark, which includes the equipment production date and equipment model information, which is convenient for the subsequent traceability and management of the cover.

[0039] In a second aspect, the present invention also provides a display module, referring to Figure 5 , including a backlight module 100 and a cover plate 200 as described in any embodiment of the present utility model.

[0040] As a preferred embodiment of the present invention, the backlight module 100 includes an LED light group 110 , and the LED light group 110 is arranged corresponding to the position of the second ink layer 210 of the cover plate 200 .

[0041] As a preferred embodiment of the present invention, the LED lamp group 110 includes a plurality of LED lamps 111, and different patterns are displayed by switching the plurality of LED lamps 111 in different zones, such as lighting only a key pattern or a personalized pattern portion, or displaying different Arabic numerals by switching in different zones.

[0042] As a preferred embodiment of the present invention, each of the plurality of LED lamps 111 is provided with a light-blocking plastic strip 120 around it, so as to prevent the light of the LED lamp from affecting the color-changing ink in other areas from changing color due to light.

[0043] As a preferred embodiment of the present invention, the backlight module 100 includes a frame 130. The frame can be a metal frame or a plastic frame.

[0044] As a preferred embodiment of the present invention, high-viscosity double-sided foam adhesive 140 is disposed around the frame 130 , and the backlight module 100 is fixed to the cover plate 200 via the high-viscosity double-sided foam adhesive 140 .
