Description

Technical Field

[0001] The utility model relates to the technical field of sunlight screens, in particular to a sunlight screen based on an external projection light source. Background Art

[0002] Sunlight screens usually require higher brightness to remain clearly visible under strong outdoor light. This leads to an increase in the backlight power of the sunlight screen, which in turn increases the amount of electrical energy converted into heat energy. Especially with the continuous advancement of technology, such as the emergence of 4K high-resolution ultra-high definition, its LCD panel has a lower light transmittance, and the backlight power needs to be further increased to meet the high brightness requirements, which also leads to more heat generation.

[0003] Secondly, direct exposure to outdoor sunlight is another important reason for the heating of the sunscreen. The intensity of outdoor sunlight is extremely high, especially for the outer frame of the sunscreen, which is generally made of metal. Under direct sunlight, the temperature rises quickly, causing the temperature of the sunscreen to rise further, which is not conducive to the heat dissipation of the sunscreen. Therefore, a new sunscreen based on external projection light source is proposed, which has better heat dissipation performance. Utility Model Content

[0007] The two sides and the top surface of the frame are fixedly connected with a middle plate;

[0008] A joint is fixedly connected to one bottom end of the channel, a fan is installed at the bottom of the joint, and the fan is installed vertically;

[0009] The back of the sunscreen is fixedly connected with a plurality of heat spreaders, the heat spreaders are bent, the ends of the heat spreaders are connected with the channels, the heat spreaders penetrate the middle plate, and the surfaces of the heat spreaders are fixedly connected with a plurality of fins.

[0010] Preferably, any of the above solutions comprises a display panel, a backlight module and a driving circuit inside the sun screen.

[0011] Adopting the above technical solution: The display panel is the core part of the sunlight screen, responsible for displaying images and video content. The liquid crystal display panel is composed of multiple layers of thin films and liquid crystal materials, and adjusts the transmission and reflection of light by controlling the arrangement of liquid crystals to form a visible image.

[0012] The backlight module provides a uniform and high-brightness light source for the LCD panel. The backlight module is usually composed of LED lamps, reflectors, light guide plates, diffusers, etc. Among them, the LED lamp provides the light source, the reflector reflects the light back to the light guide plate, and the light guide plate evenly distributes the light to the entire LCD panel.

[0013] The drive circuit is responsible for receiving and processing image signals, and then sending the processed signals to the LCD panel and backlight module to control their working status. Driven by the drive circuit, each pixel can dynamically adjust its brightness and contrast in real time. When the sunlight screen is in a strong light environment outdoors, it will automatically reduce the contrast of the overexposed part and increase the contrast of the dark part according to the intensity and direction of the external light, so that the screen content is still clearly visible under strong light.

[0014] This ensures that the screen content is still clearly visible under strong light when an external projection light source is used.

The core advantages of this device are: outstanding heat dissipation performance, installing the channel, middle plate, and cover plate on the side of the frame that is exposed to direct sunlight, the design of the channel and middle plate increases the heat dissipation surface area of ​​the frame, and installing joints and fans. The fan directly outputs airflow into the channel, and the air quickly flows through the surface of the middle plate and channel, improving the air flow on its surface, quickly taking away the heat on the frame, thereby reducing the temperature of the entire sun screen and achieving high-performance heat dissipation;

[0019] The heat spreader structure is designed to spread the heat between the back of the solar screen and the channel and middle plate of the frame, so that the heat is evenly distributed. The heat spreader is made of thermally conductive copper and is equipped with a number of large-area fins to transfer heat to a larger area on the back of the solar screen to prevent temperature accumulation.
