In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0025] The utility model provides a display cover plate for reducing the silk-screen printing process, comprising a glass substrate and a film sensor, wherein the lower surface of the glass substrate is provided with a light-shielding ink, the light-shielding ink is located in a non-display area, the lower surface of the glass substrate is coated with a transparent OCA, the transparent OCA covers the light-shielding ink, the lower surface of the transparent OCA forms a smooth plane, the film sensor is fully bonded to the glass substrate through the transparent OCA, at least one semi-transparent area is provided on the glass substrate, the transparent OCA is provided with an avoidance portion, the position, shape and number of the avoidance portion all correspond to the position, shape and number of the semi-transparent area, and each of the avoidance portions is provided with a pigment OCA.

[0026] Since the transparent OCA is applied and the lower surface of the transparent OCA forms a smooth plane, the height difference of the light-shielding ink position can be avoided, the full fitting effect is improved, and bubbles are avoided. The pigment OCA is arranged at the avoidance part of the transparent OCA, which can achieve an integrated black effect in the non-lit state and different color effects in the lit state. By adjusting the amount of pigment added, the pigment OCA with different transmittance can be modulated, thereby reducing the silk-screen printing process, reducing the production cost of the product, and improving the competitiveness of the product.

[0027] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

Since the transparent OCA4 is applied and the lower surface of the transparent OCA4 forms a smooth plane, the height difference of the position of the light-shielding ink 3 can be avoided, the full fitting effect is improved, and bubbles are avoided. The pigment OCA5 is provided at the avoidance part of the transparent OCA4, which can achieve an integrated black effect in the non-lit state and different color effects in the lit state. By adjusting the amount of pigment added, the pigment OCA5 with different transmittance can be modulated, thereby reducing the silk screen printing process, reducing the production cost of the product, and improving the competitiveness of the product.

[0029] Furthermore, the transmittance of the pigment OCA5 is 50%-90%, which can be controlled by adjusting the amount of pigment added.

[0030] Furthermore, the pigment OCA5 has one or more colors. In order to achieve semi-transparent patterns of different colors in different semi-transparent areas, pigments OCA5 of different colors can be set on different semi-transparent areas. If different color effects need to be achieved in the same semi-transparent area, different colors can also be set on the same pigment OCA5.

[0031] Furthermore, the pigment of pigment OCA5 is carbon powder, which can achieve the effect of smoked OCA.

[0032] Furthermore, the shape of the transparent OCA 4 is consistent with the shape of the film Sensor 2, so that the film Sensor 2 and the glass substrate 1 can be better fully bonded.

[0033] See also Figure 2 As a further optimization scheme of Example 1, in this embodiment, a frame-shaped overflow groove 6 is etched on the lower surface of the glass substrate 1 located in the non-visible area, and the light-shielding ink 3 is arranged on the outer surface of the overflow groove 6 and the lower surface of the glass substrate 1. Since the overflow groove 6 is provided on the lower surface of the glass substrate 1, when the OCA optical glue is applied, the OCA optical glue will overflow outward under pressure, and the excess glue will flow to and be stored in the overflow groove 6 to prevent it from continuing to diffuse outward, thereby limiting the overflow range, which can effectively prevent the overflow of the OCA optical glue and cause light leakage; the edge of the lower surface of the glass substrate 1 is provided with light-shielding ink 3, and the light-shielding ink 3 is applied on the outer surface of the overflow groove 6 and the lower surface of the glass substrate 1, and the overflow groove 6 is in the light-shielding ink 3 area at the edge of the glass substrate 1, so it will not affect the appearance of the product.

[0034] Furthermore, the shape of the overflow glue groove 6 can be convenient for the design of the etching shape, and the cross section is not limited to semicircular, V-shaped, etc. The thickness of the glass substrate 1 commonly used in the industry is about 0.8 mm, and the thickness of the OCA optical glue is about 0.1 mm. The etching depth of the overflow glue groove 6 can be designed to be 0.05 mm, and adjusted according to the actual overflow glue amount.
