Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vehicle-mounted TFT display, especially relates to the development of eliminating LED light shadow, and specifically relates to a module capable of eliminating light shadow. BACKGROUND

[0002] The distribution of each layer of the original process flow of the cover plate in the prior art is as follows: black ink→ cover bottom ink→ semi-transparent ink→ IR ink→ uniform light white ink. However, the ink thickness is inconsistent due to the influence of personnel, scraper pressure and the like in the printing process, and the brightness is uneven and the light shadow phenomenon appears after the assembly of the shell is lighted.

[0003] In the prior art, the semi-transparent ink area is printed with uniform light white ink, which causes uneven display brightness and light shadow. UTILITY MODEL CONTENTS

[0004] In view of the above phenomenon, the printing of uniform light white ink in the two semi-transparent areas is changed to paste diffusion film, and mark lines are added in the semi-transparent area to control the attachment position of the diffusion film, so that the uneven brightness and light shadow phenomenon is effectively avoided; at the same time, the defect rate of the cover plate is reduced. The printing of uniform light white ink on the cover plate is changed to paste diffusion film, which can greatly eliminate the uneven brightness and light shadow problem.

[0005] The utility model is implemented as follows:

[0006] A module capable of eliminating light shadow comprises, in sequence: a cover plate base material, a head color ink layer, a cover bottom ink layer, a semi-transparent ink layer, an IR ink layer, and a uniform light white ink layer. The IR ink layer is provided with a hole. The uniform light white ink layer is printed only on the small hole. After the cover plate process is completed, diffusion film is pasted on the two long edges of the semi-transparent ink layer.

[0007] Further, the two long edges of the semi-transparent ink layer are pasted with diffusion film.

[0008] Further, the head color ink layer and the cover bottom ink layer are black.

[0009] Further, the cover plate base material is a white sheet.

[0010] The utility model has the beneficial effects compared with the prior art:

[0011] The two long edges of the semi-transparent ink area of the utility model are not printed with uniform light white ink, and two diffusion films are pasted, so that the uneven brightness and light shadow problem is greatly eliminated.

[0012] The semi-transparent area of the utility model is printed with one ink instead of two inks, which can reduce the defect loss of the cover plate material.

[0013] The two printing of the semi-transparent area is changed into one semi-transparent printing and diffusion film is pasted, the diffusion film has good uniformity effect, and can effectively eliminate the problems of uneven brightness and lamp shadow. BRIEF DESCRIPTION OF DRAWINGS

[0017] In order to make the purpose, technical scheme and effect of the utility model more clear, the utility model is further explained in detail in the following examples. It should be pointed out that the specific implementation described here is only used to explain the utility model, and is not used to limit the utility model.

[0018] As shown in Figure 2 , the existing product semi-transparent area prints uniform white ink 6, which can cause display uneven brightness and lamp shadow, the two long edges of the semi-transparent area are not printed with uniform white ink in the utility model, and two diffusion films 7 are pasted, so that the problem of uneven brightness and lamp shadow is greatly eliminated. Specifically:

[0019] As shown in Figure 1 , the product structure of the utility model comprises in sequence: cover plate base material 1, head color ink layer 2, cover bottom ink layer 3, semi-transparent ink layer 4, IR ink layer 5; uniform white ink layer 6; the IR ink layer 5 is provided with a hole; the uniform white ink layer 6 is only printed on the small hole; after the cover plate process is finished, diffusion film 7 is pasted on the two long edges of the semi-transparent ink layer.

[0020] The preparation process of the product of the utility model is as follows: preparing cover plate base material: printing head color ink in the first way, surface drying, obtaining head color ink layer 2; printing cover bottom ink in the second way, surface drying, obtaining cover bottom ink layer 3; printing semi-transparent ink in the third way, surface drying, obtaining semi-transparent ink layer 4; printing IR ink in the fourth way, surface drying, obtaining IR ink layer 5; printing uniform white ink 6 on the hole of the semi-transparent ink in the fifth way, surface drying, and then pasting diffusion film 7 on the two long edges of the semi-transparent ink area.

[0021] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, some improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the protection range of the utility model.
