Thus, features defined with "first", "second", "third" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0028] The utility model provides a pen segment display screen with a grayscale function, which comprises a lower polarizer, a large piece of glass, a liquid crystal layer, a small piece of glass, an upper polarizer and a cover plate sequentially stacked from bottom to top. A segment electrode is arranged on the upper surface of the large piece of glass, and a common electrode is arranged on the lower surface of the small piece of glass. The segment electrode comprises a plurality of first electrode patterns and a plurality of second electrode patterns. The plurality of first electrode patterns are arranged in a rectangular array and spaced apart. Each row or column of the first electrode patterns is connected by a first ITO. Each second electrode pattern is arranged at the interval between two adjacent first electrode patterns. Each row or column of the second electrode patterns is connected by a second ITO. The arrangement directions of the first ITO and the second ITO are the same.
[0029] Due to the existence of two kinds of electrode patterns, when semi-lighting is required, lighting one of the electrode patterns can meet the semi-lighting display requirement. When full lighting is required, lighting both electrode patterns can achieve the full lighting display requirement. It can achieve two different grayscales of semi-lighting and full lighting of the pen segment display screen at a relatively low cost, thus realizing the grayscale function, reducing the cost of the pen segment display screen, and improving the competitiveness of the product.
[0030] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings. The present invention will be described in detail below with reference to the drawings and embodiments. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, but should not be construed as a limitation to the present invention.
[0031] Please refer to Figures 1 to 3, A segmented display screen with a grayscale function provided by the present utility model, which includes a lower polarizer 1, a large glass 2, a liquid crystal layer, a small glass 3, an upper polarizer 4, and a cover plate 5 stacked in sequence from bottom to top. A segment electrode 21 is provided on the upper surface of the large glass 2, and a common electrode is provided on the lower surface of the small glass 3. The segment electrode 21 includes a plurality of first electrode patterns 211 and a plurality of second electrode patterns 212. The plurality of first electrode patterns 211 are arranged in a rectangular array and spaced apart. Each row or column of the first electrode patterns 211 is connected by a first ITO 213. Each second electrode pattern 212 is disposed at the interval between two adjacent first electrode patterns 211. In this embodiment, each column of the first electrode patterns 211 is connected by a first ITO 213, and the second electrode pattern 212 is disposed longitudinally between two adjacent first electrode patterns 211. In other embodiments, the second electrode pattern 212 may also be disposed transversely between two adjacent first electrode patterns 211, or the second electrode pattern 212 may be disposed both longitudinally and transversely between two adjacent first electrode patterns 211. Each row or column of the second electrode patterns 212 is connected by a second ITO 214. In this implementation, each column of the second electrode patterns 212 is connected by a second ITO 214, and the arrangement directions of the first ITO 213 and the second ITO 214 are the same. Since there are two types of electrode patterns, when semi-lighting is required, lighting one of the electrode patterns can achieve the semi-lighting display requirement. When full lighting is required, both electrode patterns are lit to achieve the full lighting display requirement. It can achieve two different grayscales of semi-lighting and full lighting of the segmented display screen at a relatively low cost, thereby realizing the grayscale function, reducing the cost of the segmented display screen, and improving the competitiveness of the product.
[0032] Further, the occupied areas of the first electrode pattern 211 and the second electrode pattern 212 are different, so that when different grayscale displays are required, the first electrode pattern 211 or the second electrode pattern 212 can be separately turned on to achieve different brightness displays.
[0033] Further, the shapes of each of the first electrode patterns 211 are the same. Each of the first electrode patterns 211 is square, the sizes of each of the first electrode patterns 211 are the same, and the intervals between each two adjacent first electrode patterns 211 are the same.
[0034] Please refer to Figure 4, as a further optimized solution of Embodiment 1, in this embodiment, a frame-shaped glue overflow groove 51 is etched on the lower surface of the cover plate 5 located in the non-visible area, and a light-shielding ink is provided at the edge of the lower surface of the cover plate 5 located in the non-visible area. The light-shielding ink is coated on the outer surface of the glue overflow groove 51 and the lower surface of the cover plate 5. Since the glue overflow groove 51 is provided on the lower surface of the cover plate 5, when the OCA optical adhesive 6 is coated, the OCA optical adhesive 6 will be under pressure and overflow outward, and the excess glue will flow to and be stored in the glue overflow groove 51, preventing it from continuing to spread outward, thereby limiting the range of outward glue overflow, and it can effectively prevent the OCA optical adhesive 6 from overflowing and causing light leakage; a light-shielding ink is provided at the edge of the lower surface of the cover plate 5, and the light-shielding ink is coated on the outer surface of the glue overflow groove 51 and the lower surface of the cover plate 5, and the glue overflow groove 51 is in the light-shielding ink area at the edge of the cover plate 5, so it will not affect the appearance of the product.
[0035] Further, the OCA optical adhesive 6 is provided on the lower surface of the cover plate 5, and the OCA optical adhesive 6 is provided in the area formed by the glue overflow groove 51. The shape of the glue overflow groove 51 can facilitate the shape design of the etching, and the cross-section is not limited to a semicircle, a V shape, etc. The generally used thickness of the cover plate 5 in the industry is about 0.8 mm, the thickness of the OCA optical adhesive 6 is about 0.1 mm, and the etching depth of the glue overflow groove 51 can be designed according to 0.05 mm and adjusted in combination with the actual glue overflow amount.
