Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a gradient color liquid crystal display screen. Background Technology
[0002] Traditional gradient color LCD displays are usually implemented by LCD display modules. However, some gradient color displays do not require the complex display functions that LCD display modules can perform, such as color changes of various icons, which require aesthetically pleasing gradient effects. If these effects are all implemented by LCD display modules, it will increase the display area of the LCD screen. Currently, large-size LCD screens are expensive, which will significantly increase the production cost of LCD screens and reduce the competitiveness of products. Utility Model Content
[0003] The technical problem this invention aims to solve is how to enable an LCD screen to achieve aesthetic functions such as changing the color of various icons and creating gradient effects through a cover plate, thereby reducing the display area of the LCD screen, reducing the production cost of the LCD screen, and improving the competitiveness of the product.
[0004] The technical problem to be solved by this utility model is achieved through the following technical solution:
[0005] To solve the above-mentioned technical problems, this utility model provides a gradient color liquid crystal display screen, which includes a liquid crystal display module, an OCA optical adhesive, and a cover plate arranged sequentially from bottom to top. The lower surface of the cover plate is provided with photoresist ink. The photoresist ink is etched with multiple light-transmitting holes of different apertures through a photolithography process to form a gradient color area. The lower surface of the photoresist ink located in the non-visible area is provided with reverse cover ink, which avoids the gradient color area. The photoresist ink located in the gradient color area is covered with a semi-transparent ink.
[0006] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, the liquid crystal display module is a TFT display module or a TBN segment code screen.
[0007] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, the thickness of the OCA optical adhesive is 0.15mm-0.30mm.
[0008] As a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, the liquid crystal display module includes a lower polarizer, a lower substrate, an upper substrate, and an upper polarizer that are stacked sequentially from bottom to top.
[0009] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, the lower substrate is longer than the upper substrate and extends outward to form a step, and a driver IC and an FPC are bonded to the upper surface of the lower substrate located at the step.
[0010] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, an integrated insulating shielding layer is attached to the FPC. The integrated insulating shielding layer includes insulating paper and conductive shielding material disposed on the insulating paper. The area of the insulating paper is smaller than the area of the conductive shielding material. The insulating paper can completely cover the driver IC. The conductive shielding material has through holes at the edge of the insulating paper. The through holes are located in areas where no components are disposed.
[0011] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, the through hole is a round hole.
[0012] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, one end of the opening waste at the through hole is connected to the conductive shielding material.
[0013] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, double-sided adhesive is provided at the bottom of the perforated waste material.
[0014] In a preferred embodiment of the gradient color liquid crystal display screen provided by this utility model, one side of the insulating paper extends beyond the conductive shielding material.
[0015] This utility model has the following beneficial effects:
[0016] First, photoresist ink is coated onto the entire cover plate. The photoresist ink is then etched with multiple light-transmitting holes of varying sizes using a photolithography process. The design ensures that the pattern and arrangement of these holes meet aesthetic requirements. Next, reverse cover ink is screen-printed to prevent light leakage, such as pinhole defects. Then, semi-transparent ink is screen-printed on the gradient color area, allowing a gradient effect to be displayed when the backlight is on. This achieves a gradient color on the cover plate. The semi-transparent ink also improves the uniformity of the cover plate when the LCD screen is off. This structure allows the LCD screen to achieve aesthetic functions such as changing the color of various icons and creating gradient effects through the cover plate, thereby reducing the display area of the LCD screen, lowering production costs, and enhancing product competitiveness.

[0031] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0032] This utility model provides a gradient color liquid crystal display screen, which includes a liquid crystal display module, an OCA optical adhesive, and a cover plate arranged sequentially from bottom to top. The lower surface of the cover plate is provided with photoresist ink. The photoresist ink is etched with multiple light-transmitting holes of different apertures through a photolithography process to form a gradient color area. The lower surface of the photoresist ink located in the non-visible area is provided with reverse cover ink, which avoids the gradient color area. The photoresist ink located in the gradient color area is covered with a semi-transparent ink.
[0033] First, photoresist ink is coated onto the entire cover plate. The photoresist ink is then etched with multiple light-transmitting holes of varying sizes using a photolithography process. The design ensures that the pattern and arrangement of these holes meet aesthetic requirements. Next, reverse cover ink is screen-printed to prevent light leakage, such as pinhole defects. Then, semi-transparent ink is screen-printed on the gradient color area, allowing a gradient effect to be displayed when the backlight is on. This achieves a gradient color on the cover plate. The semi-transparent ink also improves the uniformity of the cover plate when the LCD screen is off. This structure allows the LCD screen to achieve aesthetic functions such as changing the color of various icons and creating gradient effects through the cover plate, thereby reducing the display area of the LCD screen, lowering production costs, and enhancing product competitiveness.
[0034] 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 with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0035] Example 1, please refer to Figures 1 to 5 This utility model provides a gradient color liquid crystal display screen, which includes a liquid crystal display module 1, an OCA optical adhesive 2, and a cover plate 3 stacked sequentially from bottom to top. The lower surface of the cover plate 3 is provided with photoresist ink 31. The photoresist ink 31 is etched with multiple light-transmitting holes of different apertures through a photolithography process to form a gradient color area 32. The lower surface of the photoresist ink 31 located in the non-visible area is provided with reverse cover ink 33, which avoids the gradient color area 32. The photoresist ink 31 located in the gradient color area 32 is covered with semi-transparent ink 34. First, photoresist ink 31 is coated onto the entire surface of the cover plate 3. The photoresist ink 31 is then etched with multiple light-transmitting holes of different sizes using a photolithography process. The pattern and aperture arrangement of the light-transmitting holes are designed to meet the appearance requirements. Then, reverse cover ink 33 is screen-printed to ensure that light leakage is avoided, such as pinhole defects. Next, semi-transparent ink 34 is screen-printed on the gradient color area 32 so that it can display a gradient effect when the backlight is on. This allows the cover plate 3 to achieve a gradient color. The semi-transparent ink 34 also makes the cover plate 3 more consistent when the LCD screen is off. This structure allows the LCD screen to achieve appearance functions such as changing the color of various icons and requiring a gradient aesthetic through the cover plate 3, thereby reducing the display area of the LCD screen, reducing the production cost of the LCD screen, and improving the competitiveness of the product.
[0036] Furthermore, both the reverse overprint ink 33 and the semi-transparent ink 34 are black.
[0037] Furthermore, the liquid crystal display module 1 is a TFT display module or a TBN segment code screen, and the thickness of the OCA optical adhesive 2 is 0.15mm-0.30mm.
[0038] Example 2, please refer to Figures 6 to 8 As a further optimization of Embodiment 1, in this embodiment, the liquid crystal display module 1 includes a lower polarizer, a lower substrate 11, an upper substrate 12 and an upper polarizer stacked sequentially from bottom to top. The lower substrate 11 is longer than the upper substrate 12 and extends outward to form a step. The upper surface of the lower substrate 11 located at the step is bonded with a driver IC and an FPC 13.
[0039] Furthermore, an integrated insulating shielding layer 4 is attached to the lower surface of the FPC13. This integrated insulating shielding layer 4 includes insulating paper 41 and conductive shielding material 42. The conductive shielding material 42 is positioned above the insulating paper 41, and the area of the insulating paper 41 is smaller than the area of the conductive shielding material 42. The insulating paper 41 completely covers the driver IC. Through-holes 43 are formed at the edges of the insulating paper 41 in the conductive shielding material 42, located in areas where no components are present. Because the conductive shielding material 42 has through-holes 43 at the edges of the insulating paper 41, the operator can see the edge of the insulating paper 41, allowing them to judge the position of the insulating paper 41 during attachment, thus avoiding misalignment or failure to attach it to the driver IC, preventing short circuits, and avoiding economic losses.
[0040] Furthermore, the through hole 43 is a round hole, and one end of the hole-opening waste is connected to the conductive shielding material 42. This allows the position of the insulating paper 41 to be observed and determined by prying open the hole-opening waste at the round hole. After aligning it, the hole-opening waste is covered back to ensure conductive shielding at the opening.
[0041] Furthermore, double-sided adhesive is provided at the bottom of the perforated waste material, which can be used to reattach the perforated waste material to ensure conductive shielding at the perforation.
[0042] Furthermore, one side of the insulating paper 41 extends beyond the conductive shielding material 42, so that the operator can determine the specific position of the insulating paper 41 by looking at the part of the insulating paper 41 that extends beyond the conductive shielding material 42, so as to avoid misalignment or failure to attach it to the driver IC, thereby preventing short circuits and avoiding economic losses.
[0043] Furthermore, the conductive shielding material 42 is conductive paper or copper foil, which can form a conductive shielding effect.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
