Description

Technical Field

[0001] The present application belongs to the technical field of display modules, and in particular, relates to a display structure capable of eliminating lamp shadows. Background Art

[0002] Optical films and optical plates are indispensable materials for LCD backlight modules, and are used in TV, monitors, notebooks, and car displays. In conventional direct-type backlight module designs, the light-emitting surface relies on the lamp beads in the middle area to emit light. Due to the light-emitting angle, number of lamp beads, and height restrictions between the module lamp beads and the optical plate, the existing module lamp bead arrangement and module architecture conditions cannot make the backlight screen bright and dark uniform. Optical materials need to be optimized and adjusted for the optics and appearance of the backlight module. The existing technical solutions will have the following problems in the process of picture optimization: replacing film materials with higher haze and higher shielding will affect the optical brightness of the backlight; replacing lamp beads with a larger light-emitting angle will make the top of the lamp beads dark, affecting the appearance of the backlight.

[0027] Example

[0028] This embodiment provides a display structure capable of eliminating lamp shadows, such as Figure 1 As shown, it includes an LED light board and a light-diffusing plate 11 arranged above the LED light board. A plurality of LED lamp beads are arranged on the LED light board. The light-diffusing plate 11 is provided with a first circular dot 12, a second circular dot 13, a third circular dot 14 and a fourth circular dot 15 printed with white ink. These circular dots are distributed from the inside to the outside, so that the light is evenly distributed on the light-diffusing plate.

[0029] Preferably, in the display structure capable of eliminating lamp shadows of this embodiment, the first circular dot 12 is provided with a diameter of 1.5 mm, which is precisely placed directly above the LED lamp bead, and its main function is to directly receive and preliminarily diffuse the strong light emitted by the LED lamp bead to avoid the glare caused by excessive concentration of light. The diameter of the LED lamp bead is optimized to 0.15 mm, ensuring that while maintaining sufficient light intensity, the possibility of light directly penetrating the light-diffusing plate is reduced.

[0030] Preferably, in the display structure capable of eliminating lamp shadows of this embodiment, 20 second circular dots 13 are provided, and the diameter is set to 0.28 mm. These dots are evenly distributed, and can further diffuse the light initially diffused by the first circular dots, so that the light is more evenly distributed on the light-distributing plate, and the appearance of bright and dark areas is reduced.

[0031] Preferably, in the display structure capable of eliminating lamp shadows of this embodiment, 28 third circular dots 14 are provided, and the diameter is set to 0.23 mm. The function of these dots is to further refine the distribution of light, improve the fineness and uniformity of the backlight image, and ensure that the image quality reaches the best state.

[0032] Preferably, in the display structure capable of eliminating lamp shadows of this embodiment, the fourth circular dots 15 are distributed at the outermost periphery of the LED lamp beads, and 6 dots are respectively arranged on both sides of the third circular dots 14, with a diameter of 0.2 mm. These dots are at the outermost layer, and their main task is to effectively diffuse the light to the entire backlight module, thereby greatly improving the overall uniformity of the backlight image and making the display effect softer and more natural.

[0033] Preferably, in the display structure capable of eliminating lamp shadows of this embodiment, the first circular dots 12, the second circular dots 13, the third circular dots 14 and the fourth circular dots 15 are made by nylon screen printing, the mesh number of the mesh is set to 305 meshes, and the thickness of the nylon screen is set to 15 μm. The printed light-dispersing plate has good light transmittance and stability, can ensure uniform distribution of light, and improve the durability of the structure.

[0034] Preferably, the display structure capable of eliminating lamp shadows of this embodiment is further provided with a fifth circular dot 16 with a density of 3 / cm2 and a diameter of 0.15 mm on the light-diffusing plate 11 outside the fourth circular dot 15, so as to further improve the fineness and uniformity of the backlight image and ensure the image quality.

[0035] The utility model uses a well-designed dot distribution and size to print white dots of the above-mentioned shape distribution on the light-distributing plate, effectively eliminating the light shadow and improving the uniformity and quality of the backlight image. At the same time, the structure is simple, easy to manufacture and install, and the cost is low, which is suitable for large-scale production.

[0036] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
