Description

Technical Field

[0001] This utility model relates to the field of notebook computer accessories technology, specifically a brightness enhancement structure for improving the backlight brightness of a notebook computer. Background Technology

[0002] A laptop backlight is a light source system used to illuminate the laptop screen. Its main function is to provide sufficient brightness so that the screen remains clearly visible in various environments. The laptop backlight is a key component ensuring screen visibility and typically uses LED technology, which features high brightness, low power consumption, and long lifespan. Its brightness adjustment and optical design in different environments have a significant impact on the user's visual experience.

[0003] In existing technologies, most backlights have limited light guide plate brightness, resulting in uneven screen brightness and affecting the user's visual experience. Especially in low-light environments, the image may appear dim and details may be lost. When the light guide brightness is insufficient, some areas of the screen may experience glare due to insufficient light, that is, the screen surface reflects dazzling light. This not only affects the viewing effect but may also cause discomfort to the user's eyes. Light uniformity is crucial for improving color performance. If the light guide brightness is limited, the screen's color performance may be restricted, resulting in color distortion or color cast, thus affecting the overall image quality.

[0004] To address this, a brightness enhancement structure for improving the backlight brightness of laptops is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a brightness enhancement structure for improving the backlight brightness of a laptop computer, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a brightness enhancement structure for improving the backlight brightness of a laptop computer, comprising a plastic iron, a light guide plate fixedly connected inside the plastic iron, a plurality of triangular grooves formed on the top of the light guide plate, a plurality of inverted triangular blocks fixedly connected to the inner wall of the triangular grooves, a plurality of dots fixedly connected to the bottom of the light guide plate, a diffuser plate fixedly connected to the outer wall of the light guide plate, a QD film fixedly connected to the side of the diffuser plate away from the light guide plate, a beam splitting film fixedly connected to the side of the QD film away from the diffuser plate, and a composite film fixedly connected to the side of the beam splitting film away from the QD film.

[0007] Preferably, a light-shielding adhesive is fixedly connected to the outer wall of the composite film, and a lamp plate is fixedly connected to the inside of the light guide plate.

[0008] Preferably, a plurality of chip protective layers are fixedly connected inside the lamp panel, and a light enhancement layer is fixedly connected to the side of the chip protective layers away from the lamp panel.

[0009] Preferably, a reflective film is fixedly connected to the outer wall of the light-enhancing layer, and a plurality of inverted cone blocks are fixedly connected to the outer wall of the reflective film.

[0010] Preferably, each of the inverted cone blocks has a chip fixedly connected inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By adopting a double-sided R-CUT triangular groove structure, the bottom R-CUT structure groove has an adjustable design, improving the light uniformity of the entire light guide plate. The double-sided R-CUT structure can increase the brightness of the light guide plate by 7-18%, making the light distribution more uniform across the entire light guide plate. This uniform light distribution helps eliminate dark and bright spots on the screen, improving the overall image quality. The combined effect of increased brightness and improved light uniformity can significantly enhance the user's visual experience. A brighter and more uniform image makes it easier for users to see details and reduces eye fatigue. The double-sided R-CUT triangular groove structure, with its adjustable bottom R-CUT structure groove, can significantly improve the brightness and light uniformity of the light guide plate, thereby bringing a better visual experience, increasing product competitiveness, and adapting to more application scenarios.

[0013] 2. By incorporating an inverted pyramid structure that modifies the angle of light, the large-angle light emitted by the LEDs is reflected by the sidewalls of the frame, altering the angle of propagation and allowing the light to pass upwards. This inverted pyramid design effectively utilizes light that might otherwise be lost or wasted, improving light efficiency and enhancing the brightness of the display screen. Furthermore, the reflection from the frame sidewalls ensures a more uniform light distribution over a wider area. This design helps eliminate dark and bright spots on the screen, resulting in more uniform light distribution across the entire display and improved overall image quality.

[0025] Better: In the laptop backlight system, the heat exchanger 1 helps dissipate heat and reduce component temperature. Good thermal management can extend the lifespan of the LED light source. The light guide plate 2 can effectively utilize the light from the LED light source and improve the overall brightness output. By optimizing the structure and materials of the light guide plate 2, light loss can be minimized, thereby improving the display effect. The double-sided R-CUT triangular groove 8 structure has an adjustable design within the R-CUT groove on the bottom surface, improving the light uniformity of the entire surface of the light guide plate 2. The double-sided R-CUT structure can improve the brightness of the light guide plate 2 by 7-18%, making the light on the entire surface of the light guide plate 2 more uniform. The design of the diffuser plate 3 can enhance the color performance of the display.

By preventing light interference, the light-shielding adhesive ensures that the display maintains color consistency under different brightness levels. The light source type and configuration of the lamp panel 11 directly affect the color performance of the display. A high-quality lamp panel 11 can provide a wider color gamut and higher color saturation, making the displayed images more vivid and realistic. The chip protection layer 13 can optimize light propagation and distribution. By selecting appropriate materials and thickness, the protection layer can improve light transmittance and ensure the brightness and uniformity of the backlight. The brightness enhancement layer 12 and the reflective film 14 are components that can improve the brightness and contrast of the liquid crystal display screen.
