[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-6 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment 1: A design method for improving screen brightness. The specific steps of the method for improving screen brightness are as follows: S1, using a laser cutting machine to cut a V-shaped notch on the glossy surface of the backlight panel; S1-1, placing the backlight plate on the laser cutting machine so that the light surface of the backlight plate is located under the cutting head of the laser cutting machine; S1-2, programming the V-groove cutting data into the laser cutter to open a V-groove on the light surface of the backlight panel; S1-2-1, select the laser head; S1-2-2, set the workpiece coordinate system, absolute coordinates and laser intensity, perform programming operations, and import programming data into the laser cutter; S1-2-3, the laser cutter creates a V-groove on the light surface of the backlight panel according to the programming data; The slotting operation on the light surface of the backlight panel is completed by laser cutting. The angle error of the slotted slot is small, which can better diffuse the light and improve the brightness of the light. There will be no problems such as high cost, high power consumption, difficult heat dissipation, and low reliability. It is more suitable for the current backlight panel production operation. S1-2-4, the angle of the V-groove is 60 degrees; S2, using a laser cutting machine to cut dots on the back of the backlight panel; S2-1, placing the backlight plate on the laser cutting machine so that the dot surface of the backlight plate is located under the cutting head of the laser cutting machine; S2-2, by programming the cutting data of the dots into the laser cutter, the dots are opened on the dot surface of the backlight plate; S2-2-1, select the laser head; S2-2-2, set the workpiece coordinate system, absolute coordinates and laser intensity, perform programming operations, and import programming data into the laser cutter; S2-2-3, the laser cutter opens dots on the dot surface of the backlight panel according to the programming data; Laser cutting is used to complete the slotting operation of the backlight panel. Although the slotting cost increases, it can effectively reduce the scrap rate of the backlight panel, thereby achieving the effect of increasing production, and is more suitable for the current backlight panel production operation; S2-2-4, the depth of the dots is less than or equal to one-fourth of the thickness of the backlight panel; The dot depth is one-fourth of the backlight thickness to ensure uniformity of light propagation in the backlight. The design of maintaining the same depth helps maintain the overall light distribution and reduce possible light intensity differences. The light propagation inside the backlight will be more consistent, which helps maintain the overall lighting effect. In addition, the smaller dot depth helps reduce the possibility of optical distortion, making the control of light propagation more stable. The difference between the apertures of adjacent dots is equal, which reduces the light intensity difference and ensures consistent optical performance of the light guide plate over the entire surface. S3, using a laser cutting machine to cut the cut dots, cut out reflective grooves, and apply reflective paint inside the dots; The irradiation angle of the light is the same as the angle of the inclined plane of the V-shaped groove. In order to better complete the diffusion of light, when the light is irradiated to the reflective groove, controlling the total depth of the reflective groove helps to ensure that the light is normally emitted from the backlight panel. The included angle of the reflective groove is set to 45 degrees. When the 30-degree light is irradiated on the 45-degree reflective surface, the light will be reflected by the reflective groove wall. The reflected light is reflected again by the reflective paint. After being reflected by the paint, the light is reflected again to the reflective groove wall for refracting. The light is also reflected at the same time. Diffusion of the light can make the initial point and the end point of the light different, so that the light irradiated on the V-shaped groove wall can be reflected several times, which better improves the brightness of the light and improves the light propagation efficiency.

[0020] S3-1, after the laser cutter opens the dot surface of the backlight panel according to the programming data, the new programming data is imported into the laser cutter; Laser cutting is used to complete the slotting operation of the backlight panel. Although the slotting cost increases, it can effectively reduce the scrap rate of the backlight panel, thereby achieving the effect of increasing production, and is more suitable for the current backlight panel production operation; S3-2, the laser cutter further opens a reflective groove on the inner wall of the dot; Laser cutting is used to complete the grooving operation of the reflective groove of the backlight panel. The angle error of the groove is small, so that the starting point and the end point of the light are different, so that the light irradiated on the V-shaped groove wall can be reflected several times, which better improves the brightness of the light.

[0021] S3-3, the reflection groove is conical, the angle formed by the reflection groove is 45 degrees, and the depth of the reflection groove is less than or equal to one quarter of the depth of the dot; The included angle of the reflection groove is set to 45 degrees. When the 30-degree light is irradiated on the 45-degree reflection surface, the light will be reflected by the reflection groove wall, and the reflected light will be reflected again by the reflective paint. After being reflected by the paint, the light will be reflected again to the reflection groove wall and refracted. The light will also be reflected at the same time and diffused, so that the initial point and end point of the light can be different, and the light diffusion effect is better.

[0022] S3-4, applying reflective paint on the inner wall of the top of the reflective groove opened in the network point, the reflective paint application range is annular, and the applied paint is located in the reflective groove; Applying reflective paint in the reflective groove can increase light reflection, reduce light absorption and scattering, effectively improve light utilization efficiency, ensure that more light is guided to the light surface of the backlight panel, and enhance the light output effect; Scattered light has a positive impact on the visual perception of light, because the light of LED lights is not enhanced. After the light is diffused, it becomes softer, reducing the stimulation of strong light and shadow on the observer's eyes and improving visual comfort; S4, the reflector is fixed on the frame, and the LED light is installed at the bottom of the frame; S4-1, fix the reflector on the frame, and then fix the LED light under the frame; S4-2, the LED lamp is placed at an angle of 30 degrees, so that the irradiation direction of the LED lamp is along the direction of the V-shaped groove; By setting the LED lights at a 30-degree angle, the illumination angle of the LED light is along the direction of the V-groove, increasing the number of diffuse reflections of the light source and achieving higher screen brightness.

[0023] S5, turn on the LED light, and the light shines on the reflective groove wall to diffuse the light; S5-1, turn on the LED light, and irradiate the light at an angle of 30 degrees; S5-2, the light is irradiated into the wall of the reflective groove, the reflective groove wall reflects the light, the reflected light is reflected again by the reflective coating, the light is reflected by the coating and then reflected again to the wall of the reflective groove, refracted, and the light is also reflected at the same time, so as to diffuse the light; S6, the diffused light passes through the backlight plate and shines on the V-shaped groove, undergoing multiple diffuse reflections; S6-1, the diffused light passes through the backlight panel, and the backlight panel lights up; S6-2, the diffused light shines on the V-groove, and the light undergoes multiple diffuse reflections to increase the brightness of the screen.
