Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a liquid crystal display that can improve display effect. Background Technology

[0002] Segment LCD screens, also known as segment display screens, are only suitable for displaying simple numbers and characters. They primarily replace LED digital tubes (composed of 7 segments for displaying numbers 0-9). Currently, non-dot-matrix LCD screens are generally referred to as segment LCDs, a type of LCD product. However, within the LCD industry, they are commonly called pattern LCDs, segment LCDs, monochrome LCDs, etc. They are mainly used in applications such as calculators and clocks, where the displayed content is purely numerical and relatively simple.

[0003] Conventional VA display mode magnification products have very small display segments, with the thinnest line width being only 0.05mm. Furthermore, due to the orientation problem of liquid crystal molecules, misalignment occurs at the edges of the displayed pattern due to the electric field, resulting in "ripples" and "burrs" at the edges of the displayed pattern, affecting the overall display effect. Therefore, a liquid crystal display screen that can improve the display effect is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a liquid crystal display screen that can improve the display effect, which can enlarge the display screen of the conventional display and design a BM layer to block the position of the enlarged area, so as to retain only the pattern display in the center position.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A liquid crystal display screen that can improve the display effect includes a glass cover and a segment display pattern. The glass cover has a display area and a non-display area at a position outside the display area. The display area has a segment pattern display area and a non-segment pattern display area. A segment liquid crystal display module is attached to the bottom of the glass cover.

[0007] The segmented liquid crystal display module includes an upper glass substrate, a liquid crystal filling layer and a lower glass substrate, which are arranged from top to bottom to form the segmented liquid crystal display module.

[0008] A BM layer is provided on the side of the upper glass substrate facing the lower glass substrate. The BM layer has a pattern cutout area, and the size of the pen segment display pattern is larger than the size of the pattern cutout area.

[0009] Furthermore, the bottom of the non-display area is screen-printed with a first layer of black light-blocking ink.

[0010] Furthermore, the top of the upper glass substrate has an upper polarizer, which is attached to the bottom of the glass cover plate.

[0011] Furthermore, a lower polarizer is attached to the bottom of the lower glass substrate, and the lower polarizer is used to be attached to the backlight module at the bottom.

[0012] Furthermore, a sealing frame is provided at the edges of the upper and lower glass substrates on opposite sides, and the liquid crystal filling layer is filled within the sealing frame.

[0013] Furthermore, the size of the BM layer is smaller than the size of the area enclosed by the sealing frame.

[0014] Furthermore, an upper electrode layer is provided at the bottom of the BM layer, and a lower electrode layer is provided at the top of the lower glass substrate.

[0015] Furthermore, the BM layer, except for the pattern cutout area, consists entirely of black ink opaque areas.

[0016] Furthermore, a second black light-blocking ink layer is coated on the bottom of the non-segment pattern display area;

[0017] The size of the pen-segment pattern display area corresponds to the position of the pen-segment pattern, while the size of the pen-segment pattern display area is smaller than the size of the pattern cutout area.

[0018] Furthermore, both the upper electrode layer and the lower electrode layer are ITO electrode layers.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The liquid crystal display screen provided by this utility model can improve the display effect by enlarging the conventional segment display pattern as a whole and designing a BM layer to block the edge of the enlarged area, leaving only the pattern in the center for display. Because the edge of the segment display pattern after enlargement is blocked by the area outside the pattern cutout area in the BM layer, the display abnormality caused by the electric field at the edge will not be displayed, thus improving the overall display effect.

[0021] By designing the segmented pattern display area, the edges of the displayed image that passes through the pattern cutout area within the BM layer can be further shielded, avoiding incomplete shielding by the BM layer. This further ensures a better display effect of the segmented pattern seen from the outside of the glass cover. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0041] As described in the background section, conventional VA display mode magnification products have very small display segments, with the thinnest line width being only 0.05mm. Furthermore, due to the orientation problem of liquid crystal molecules, poor orientation will occur at the edges of the display pattern to be displayed due to the electric field, resulting in "ripples" and "burrs" at the edges of the display pattern, affecting the overall display effect.

[0042] To solve this technical problem, this utility model provides a liquid crystal display screen that can improve the display effect, which is applied to liquid crystal display screens.

[0043] For details, please refer to Figures 1-9 As shown, the liquid crystal display screen that can improve the display effect specifically includes a glass cover plate 1 and a segment display pattern 3. The glass cover plate 1 has a display area 11, and a non-display area 12 is located on the glass cover plate 1 at a position outside the display area 11. The display area 11 has a segment pattern display area 110 and a non-segment pattern display area 111. A segment liquid crystal display module 2 is attached to the bottom of the glass cover plate 1.

[0044] The segmented liquid crystal display module 2 includes an upper glass substrate 21, a liquid crystal filling layer 22 and a lower glass substrate 23, which are arranged from top to bottom to form the segmented liquid crystal display module 2.

[0045] Among them, a BM layer 24 is provided on the side of the upper glass substrate 21 facing the lower glass substrate 23, and the BM layer 24 has a pattern cutout area 25. The size of the pen segment display pattern 3 is larger than the size of the pattern cutout area 25.

[0046] The liquid crystal display screen provided by this utility model can improve the display effect. It enlarges the conventional segment display pattern 3 as a whole and designs a BM layer 24 to block the edge of the enlarged area, leaving only the pattern in the center for display. Because the edge of the segment display pattern after enlargement is blocked by the area outside the pattern cutout area 25 in the BM layer 24, the display abnormality caused by the electric field at the edge will not be displayed, thus improving the overall display effect.

[0047] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0048] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] Example 1

[0051] Please refer to Figures 1-9 As shown, a liquid crystal display screen that can improve the display effect includes a glass cover plate 1 and a segment display pattern 3. The glass cover plate 1 has a display area 11 and a non-display area 12 on the glass cover plate 1 at a position outside the display area 11. The display area 11 has a segment pattern display area 110 and a non-segment pattern display area 111. A segment liquid crystal display module 2 is attached to the bottom of the glass cover plate 1.

[0052] The segmented liquid crystal display module 2 includes an upper glass substrate 21, a liquid crystal filling layer 22 and a lower glass substrate 23, which are arranged from top to bottom to form the segmented liquid crystal display module 2.

[0053] Among them, a BM layer 24 is provided on the side of the upper glass substrate 21 facing the lower glass substrate 23, and the BM layer 24 has a pattern cutout area 25. The size of the pen segment display pattern 3 is larger than the size of the pattern cutout area 25.

[0054] The pen segment display pattern 3 in this embodiment has been enlarged, that is, the pen segment display pattern 3 initially displayed on the display screen in this embodiment is larger than the final pattern size seen on the outside of the glass cover plate 1;

[0055] In this way, when the pen segment display pattern 3 is actually displayed, the edges of the magnified pen segment display pattern 3 will be blocked by the BM layer 24 outside the pattern cutout area 25, while the pattern in the center of the pattern can be seen on the glass cover plate 1 through the pattern cutout area 25. Therefore, the display abnormality caused by the electric field at the edge of the pen segment display pattern 3 will not be displayed on the outside, thus improving the overall display effect.

[0056] The bottom of the non-display area 12 is screen-printed with a first black light-blocking ink layer 120. Through the design of the first black light-blocking ink layer 120, the area below the non-display area 12 can be blocked, so that the non-display area 12 appears black as a whole, which better highlights the content displayed in the display area 11 inside.

[0057] Example 2

[0058] The liquid crystal display screen provided in Embodiment 1, which can improve the display effect, is further optimized, specifically, as follows: Figure 4 As shown, the top of the upper glass substrate 21 has an upper polarizer 210, which is attached to the bottom of the glass cover plate 1. The bottom of the lower glass substrate 23 is attached to a lower polarizer 230, which is used to attach to the backlight module 4 at the bottom.

[0059] A sealing frame 26 is provided at the edges of the upper glass substrate 21 and the lower glass substrate 23 on opposite sides. The liquid crystal filling layer 22 is filled in the sealing frame 26. The size of the BM layer 24 is smaller than the size of the area enclosed by the sealing frame 26.

[0060] The bottom of the BM layer 24 is also provided with an upper electrode layer 211, and the top of the lower glass substrate 23 is also provided with a lower electrode layer 231. Both the upper electrode layer 211 and the lower electrode layer 231 are ITO electrode layers.

[0061] Except for the pattern cutout area 25, the BM layer 24 is a black ink light-blocking area. By adopting the design of black ink light-blocking area, the edges of the pen segment display pattern 3 after magnification can be blocked, leaving only the pen segment display pattern 3 in the center to pass through and be displayed to the outside. Therefore, display abnormalities caused by electric field at the edges will not be displayed to the outside, thus improving the overall display quality.

[0062] Example 3

[0063] The liquid crystal display screen provided in Embodiment 1 or 2, which can improve the display effect, is further optimized, such as... Figure 3As shown, the bottom of the non-segment pattern display area 111 is coated with a second black light-blocking ink layer 112. In this way, the design of the second black light-blocking ink layer 112 can cover the area outside the segment pattern display area 110, while only the pattern within the segment pattern display area 110 is displayed on the glass cover plate 1.

[0064] Wherein, the size of the segment pattern display area 110 corresponds to the position of the segment display pattern 3 and the pattern cutout area 25, and the size of the segment pattern display area 110 is smaller than the size of the pattern cutout area 25.

[0065] Through the above structural design, after the edge of the segment display pattern 3 on the LCD module is blocked once by the pattern cutout area 25, the display area will be blocked again by the second black light-blocking ink layer 112 on the non-segment pattern display area 111. The final pattern displayed on the outside will be smaller than the size of the pattern cutout area 25. Therefore, the segment display pattern 3 is blocked twice, further blocking the display abnormality at the edge and avoiding the situation of incomplete blocking.
