Description

Technical Field

[0002] In the field of display technology, traditional backlight modules typically use LED light strips combined with light guide components to diffuse light, and then use ordinary prism structures to focus the light.

[0038] refer to Figures 1-9 This utility model discloses an eye-protection display 100, including a main body 1000. The main body 1000 includes a display panel 1001, a first prism layer 2000, a light guide assembly 3000, and a light source assembly 4000. The light source assembly 4000 generates light, which passes sequentially through the light guide assembly 3000, the focusing prism, and the display panel 1001 to display an image. Figure 3As shown, the first prism layer 2000 includes several protruding first condensing prisms 2001. Each first condensing prism 2001 includes a first bottom surface 2002, a first top surface 2003, and a first side surface 2004 connecting the first bottom surface 2002 and the first top surface 2003. The first side surface 2004 is arc-shaped. The arc-shaped side surface of the first condensing prism 2001 enables smoother light transmission during refraction and reflection, reducing the stimulation of direct, high-intensity beams on the eyes, reducing glare and scattered light, effectively reducing eye fatigue, and thus better protecting the viewer's vision.

[0039] In this embodiment, the width of the first focusing prism 2001 gradually decreases from the first bottom surface 2002 to the first top surface 2003. This structure allows the light generated by the light source assembly 4000 to be more concentrated and refracted more uniformly onto the display panel 1001, improving overall optical uniformity and resulting in a more stable image display with no significant brightness differences.

[0040] In this embodiment, the first top surface 2003 is arc-shaped, and the first bottom surface 2002 is flat. The arc-shaped first top surface 2003 allows the light passing through the first focusing prism 2001 to obtain a smoother refraction curve when emitted, thus making the light focusing more precise and gentle. The flat bottom surface provides a stable and uniform incident light environment, ensuring that the light is in a consistent state before entering the prism structure. Through the above structure, the focusing effect of the light can be effectively improved, ensuring the uniform distribution of light spots on the display panel 1001 and reducing the problems of local overbrightness or overlapping light spots.

[0041] As a preferred embodiment, the main body 1000 further includes a second prism layer 5000, such as... Figure 4 As shown, the second prism layer 5000 has several protruding second focusing prisms 5001, such as... Figure 2-4 As shown, the first condensing prism 2001 and the second condensing prism 5001 are set at an angle. By setting an angle between the first condensing prism 2001 and the second condensing prism 5001, a multi-level control optical path system is formed. The first condensing prism 2001 first guides and focuses the light. When the modulated light enters the second prism layer 5000, the second condensing prism 5001 further finely adjusts the direction and distribution of the beam, so that the light can be more evenly irradiated on the display panel 1001, reducing local overbrightness or unevenness, thus making the picture more stable and softer, thereby reducing eye fatigue during long-term use and significantly improving the eye protection effect.

[0042] As a preferred embodiment, the first condensing prism 2001 and the second condensing prism 5001 are arranged at an acute angle, a right angle, or an obtuse angle.

[0043] Specifically, in this invention, the first focusing prism 2001 and the second focusing prism 5001 are set at a right angle, which effectively solves the problem of high energy concentration caused by direct light. After adjustment by the first focusing prism 2001 and the second focusing prism 5001, the emitted beam is more uniform and softer, which can significantly reduce glare. For users who use the monitor for a long time, it can effectively relieve eye fatigue and achieve a better eye protection effect.

[0044] In this embodiment, the second condensing prism 5001 includes a second bottom surface 5002, a second top surface 5003, and a second side surface 5004 connecting the second bottom surface 5002 and the second top surface 5003. The second side surface 5004 is an arc-shaped side surface, the second top surface 5003 is an arc-shaped top surface, and the second bottom surface 5002 is a flat bottom surface. The width of the second condensing prism 5001 gradually decreases from the second bottom surface 5002 to the second top surface 5003. By adding a second prism layer 5000, and the second prism layer 5000 having an arc-shaped side surface and an arc-shaped top surface, fine focusing, balanced distribution, and efficient utilization of light are further achieved, thereby reducing glare, improving optical efficiency, and enhancing visual comfort and eye protection to a greater extent.

[0045] In this embodiment, the second prism layer 5000 is disposed above the first prism layer 2000, and the first top surface 2003 of the first condensing prism 2001 and the second top surface 5003 of the second condensing prism 5001 both face the display panel 1001. Through this structure, the light can be further focused and homogenized, resulting in a more uniform distribution of the light beam refracted onto the display panel 1001.

[0046] In this embodiment, the light guide assembly 3000 includes a light guide plate 3001, which reduces the stimulation of the eyes by direct and concentrated light beams, reduces glare, and thus helps to alleviate eye discomfort and visual fatigue that may be caused by prolonged use of the display, significantly improving eye protection performance.

[0047] In this embodiment, the light source component 4000 is disposed at the side edge of the light guide plate 3001, thereby achieving efficient light energy coupling and transmission, reducing light energy loss during transmission. The above structure also makes the display structure more compact, the product thinner and lighter, and provides users with a better product experience.

[0048] Specifically, the light guide plate 3001 is an acrylic light guide plate 3001. Acrylic material has high transparency, thereby reducing light loss during transmission. At the same time, due to the high refractive index of acrylic, the incident light can be effectively transmitted through the principle of total internal reflection and evenly diffused into a surface light source, ensuring uniform brightness in all areas of the display panel 1001 and eliminating hot spot phenomena.

[0049] Preferably, the acrylic light guide plate 3001 is an acrylic light guide plate 3001 formed by hot pressing. The hot pressing process can realize the high-precision microstructure of the acrylic light guide plate, effectively improve the optical uniformity, and the hot pressing process can reduce material waste, have a high utilization rate, and effectively save manufacturing costs.

[0050] In other embodiments, the light guide plate 3001 may also be a silicone light guide plate 3001, a glass light guide plate 3001, or a polycarbonate (PC) light guide plate 3001.

[0051] In this embodiment, the light guide plate 3001 has an upper surface 3002 and a lower surface 3003 opposite to the upper surface 3002. The upper surface 3002 is disposed facing the display panel 1001, and a reflective film 3004 is disposed on the lower surface 3003. The reflective film 3004 is configured to reflect the light emitted by the light source assembly 4000 to the lower surface 3003 back to the upper surface 3002. Through the cooperation of the reflective film 3004, the light guide plate 3001 transforms the light generated by the light source assembly 4000 from a line light source into a surface light source. By setting the reflective film 3004, the light efficiency loss caused by light energy loss is effectively reduced, thereby improving the overall optical efficiency and display brightness, making the surface light source output formed on the display panel 1001 more uniform and stable, and avoiding glare caused by excessive brightness in some areas.

[0052] In this embodiment, the main body 1000 also includes a biprism film 1002, which is disposed between the second prism layer 5000 and the display panel 1001. The biprism film 1002 can filter polarized light that does not meet the requirements of the display panel 1001, reduce glare caused by scattering and reflection, and thus improve the contrast of the picture.

[0053] Preferably, the double-prism film 1002 is a DBEF (Dual Brightness Enhancement Film) reflective polarization film. DBEF reflective polarization film has highly efficient polarization selectivity, which helps improve the brightness and contrast of the displayed image. It enables the color components in the light output from the display panel 1001 to maintain a good balance, thereby improving the overall color saturation and contrast of the image, making the picture more vivid and realistic. It also ensures that the display effect remains stable and excellent under different environments.

[0054] In this embodiment, the biprism film 1002 has a first atomizing surface 1003, and the atomization range of the first atomizing surface 1003 is 40%-85%. By setting the first atomizing surface 1003, the light modulated by the second prism layer 5000 can be made more uniform, avoiding the phenomenon of local over-brightness or under-brightness caused by concentrated light spots, and achieving a more ideal surface light source effect.

[0055] In this embodiment, the main body 1000 further includes a first diffusion film 1004, which is disposed between the light guide assembly 3000 and the first prism layer 2000. The first diffusion film 1004 is used to diffuse the light generated by the light source assembly 4000 toward the second prism layer 5000. The first diffusion film 1004 has a second atomized surface 1201, the atomization range of which is 86%-95%. The first diffusion film 1004 can sufficiently scatter the light from the light guide plate 3001, causing the light entering the second prism layer 5000 to exhibit a wider angular distribution, thereby contributing to the uniformity of the light field on the entire display panel 1001 and avoiding obvious local hot spots or dark areas.

[0056] In this embodiment, the main body 1000 further includes a second diffusion film 1005, which is disposed between the biprism sheet film 1002 and the display panel 1001. The second diffusion film 1005 is used to diffuse light toward the display panel 1001, and the second diffusion film 1005 has a third atomized surface 1202, the atomization range of which is 40%-85%. By setting the second diffusion film 1005, the light is further diffused and softened, effectively avoiding local brightness inconsistencies and ensuring a consistent light field across the entire display panel 1001.

[0057] In this embodiment, the main body 1000 also includes a cover plate 1006 disposed above the display panel 1001. The cover plate 1006 is a diffuse reflection glass cover plate 1006. The surface structure of the diffuse reflection glass can effectively scatter incident light, so that the light from the display panel 1001 or the environment is uniformly diffused when passing through the cover plate 1006, avoiding the formation of obvious reflection hotspots or specular reflection effects, thereby reducing glare and improving visual comfort.

[0058] In this embodiment, the cover plate 1006 has a fourth atomized surface 1007, and the first atomized surface 1003 is disposed facing the fourth atomized surface 1007. By disposing of the first atomized surface 1003 and the fourth atomized surface 1007, the light passing through the cover plate 1006 is uniformly dispersed before entering the display panel 1001, further eliminating local highlights and dark areas, thereby achieving a more uniform light field distribution. Specifically, the fourth atomized surface 1007 is formed by etching the cover plate 1006 with an acidic solvent. The atomization range of the fourth atomized surface 1007 is 2.8%-8%, and the light transmittance range of the fourth atomized surface 1007 is 96%-99%.

[0059] In this embodiment, the light source assembly 4000 includes at least one LED strip 4001, which is disposed at the edge of the light guide assembly 3000. The LED strip 4001 includes a plurality of LED beads 4002, which are low-blue-light, high-color-gamut LED beads. By using low-blue-light, high-color-gamut LED beads 4002, the output of blue light is effectively reduced, thereby alleviating stimulation to the retina and improving eye protection for users who use the monitor for extended periods.

[0060] In this embodiment, the blue light chip of the LED bead 4002 emits light in the range of 457nm-485nm, and phosphor is disposed in the beam path of the LED bead 4002. By limiting the blue light band of the LED bead 4002 to 457nm to 485nm, not only is precise white light matching and color balance achieved, but the matching phosphor conversion technology can also be better utilized to obtain a more balanced and natural white light effect and achieve excellent color reproduction performance.

[0061] In this embodiment, the main body 1000 also includes a frame assembly 1008, which includes a housing 1101. A cover plate 1006 is placed on the housing 1101 and forms a sealed cavity 1102 with the housing 1101. The display panel 1001, the first prism layer 2000, the light guide assembly 3000, and the light source assembly 4000 are all disposed in the sealed cavity 1102. Through the above structure, the scattering and absorption of light transmission path caused by dust and moisture in the air can be effectively avoided, thereby improving the optical efficiency and brightness of the display panel 1001, while ensuring more uniform color reproduction and brightness distribution.

[0062] In this embodiment, the frame assembly 1008 further includes a fixing bracket 1103, which is installed inside the housing 1101 to fix the display panel 1001 to the housing 1101, so as to prevent the display panel 1001 from shifting or shaking due to vibration or external force, thereby ensuring that the display panel 1001 is always in the best display state.

[0063] In this embodiment, a collision-resistant strip 1104 is also provided on the side edge of the mounting bracket 1103. The collision-resistant strip 1104 is configured to prevent the display panel 1001 from rubbing against and colliding with the mounting bracket 1103. Specifically, the collision-resistant strip 1104 is made of foam adhesive. As a soft material, foam adhesive has good elasticity and shock absorption properties, and can form an effective isolation layer between the display panel 1001 and the mounting bracket 1103. When the display panel 1001 is subjected to external impact or undergoes slight displacement, the foam adhesive can absorb and buffer the impact energy, thereby preventing the panel from directly colliding with or rubbing against the mounting bracket 1103.

[0064] In this embodiment, a DC constant current chip 1009 is also electrically connected to the display panel 1001. The DC constant current chip 1009 is used to adjust the current of the light source component 4000 to linearly adjust the brightness of the light source component 4000, thereby ensuring the balance and stability of image display at different brightness levels and improving the overall color accuracy and contrast of the display.

[0065] In this embodiment, the main body 1000 also includes a driver board 1010 and an FPC cable board 1011, which are electrically connected to the display panel 1001. This structure not only optimizes signal transmission and system integration but also improves the product's overall performance in terms of thinness, stability, and ease of maintenance.
