Description

Technical Field

[0001] The utility model provides a liquid crystal display module with temperature compensation, belonging to the technical field of liquid crystal display module temperature compensation. Background Technique

[0002] A liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses an electric current to stimulate liquid crystal molecules to generate dots, lines, and planes, combined with a backlight tube to form an image. Its working principle is that under the action of an electric field, the arrangement direction of liquid crystal molecules changes, causing the light transmittance of an external light source to change, completing the electro-optical conversion, and then using different excitations of R, G, and B primary color signals, through red, green, and blue primary color filter films, to complete the color reproduction in the time domain and spatial domain. The physical properties of a liquid crystal display module are greatly affected by the ambient temperature. Temperature changes will cause offsets in the electrical performance and performance of the liquid crystal display module. For example, when the temperature rises, leakage current will be generated in the transistors inside the liquid crystal display module, resulting in unstable or distorted display images, thus affecting the display quality. Therefore, in order to ensure the stability and reliability of the liquid crystal display module, temperature compensation is required.

[0003] Patent number: CN217361054U; discloses a liquid crystal display module with temperature compensation function, including a liquid crystal display and a temperature compensation box. Four sleeves are fixed on the outer wall of the liquid crystal display. Clamping plates are inserted on the sleeves, and the clamping plates are slidably matched with the inner walls of the sleeves. Threaded holes are opened on the sleeves, and bolts are threadedly connected in the threaded holes. The bolts are used to fix the sleeves and the clamping plates. The liquid crystal display is fixed on the temperature compensation box through four clamping plates. Blowers are fixedly installed on the opposite sides of the temperature compensation box, and the air inlet ends of the blowers are fixedly communicated with air ducts.

[0004] The above patent drives the water circulation among the water storage tank, two transfer tanks, and multiple heat exchange tubes through a water pump. The electric heating wire inside the water storage tank can heat the water inside the water storage tank, so that the heat exchange tubes and heat exchange fins cooperate with each other to provide temperature compensation for the liquid crystal display, ensuring the stable operation of the liquid crystal display in a cold environment. However, the rear housing of the liquid crystal display is usually made of plastic, and there is a certain gap between the rear housing and the transistors. The rear housing is in direct contact with the heat dissipation fins of the temperature compensation box. When the water temperature in the water storage tank is relatively high, it will cause the temperature of the heat exchange tubes and heat dissipation fins to be relatively high, thus melting the rear housing of the liquid crystal display. When the temperature is relatively low, due to the gap between the rear housing and the transistors, the temperature compensation effect is not ideal. Content of the Utility Model

[0005] The liquid crystal display module with temperature compensation provided by the utility model can solve the problems that the existing device will melt the rear housing of the liquid crystal display when the temperature is relatively high and the temperature compensation effect is not ideal when the temperature is relatively low.

[0006] In order to solve the above problems, the technical solution proposed by the present utility model is as follows: A liquid crystal display module with temperature compensation, including a liquid crystal display; an installation frame is provided at the rear of the liquid crystal display, several regular installation holes are provided in the installation frame, a hot air blower is installed in the installation holes, the air outlet end of the hot air blower is located in the installation holes, and several isolation columns are provided at one end of the installation frame close to the liquid crystal display;

[0007] As an improvement, U-shaped blocks with downward openings are provided on both sides above the installation frame, L-shaped connecting rods that slide downward are provided inside the U-shaped blocks, a fixing hole is provided in the middle above the U-shaped blocks, several fixing holes are provided at equal intervals above the connecting rods, and the positions of the U-shaped blocks and the connecting rods are fixed by positioning pins;

[0008] As an improvement, sleeve rods are respectively provided on both sides of the installation frame, L-shaped fixing rods that slide inside and have openings facing the middle of the device are provided inside the sleeve rods, a fixing hole is provided in the middle above the sleeve rods, several fixing holes are provided at equal intervals above the fixing rods, and the positions of the sleeve rods and the fixing rods are fixed by positioning pins;

[0010] As an improvement, the circuits between several hot air blowers are connected in parallel with each other.

[0011] Advantages of the present utility model:

[0012] By setting the hot air blower, the hot air blown out by the hot air blower can enter the inside of the liquid crystal display through the heat dissipation holes at the rear of the liquid crystal display, thereby compensating the temperature of the transistors. When blowing cold air, it can cool down the transistors. By setting the isolation columns, the hot air blower does not directly contact the liquid crystal display, thereby avoiding damage to the liquid crystal display. Description of the Drawings

When blowing cold air, it can cool the transistor. By setting the isolation posts 5, the hot air blower 4 does not directly contact the liquid crystal display, so as to avoid damage to the liquid crystal display 1.
