Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display screens, and in particular to a curved liquid crystal display screen and a manufacturing method thereof. Background Art

[0002] With the development of technology, users have put forward higher requirements for the display effect and structural diversification of display devices. Curved LCD screens, due to their unique design, can provide better visual experience and aesthetic value, meeting users' needs for novel design and good visual experience.

[0003] After searching, the Chinese patent publication number CN110361878A discloses a curvature design of a curved liquid crystal display screen and a manufacturing method thereof. Although the technology can automatically select a suitable curvature according to data and produce a curved display screen whose curvature meets the actual situation of consumers, making it more comfortable for consumers to use, the best viewing position of the curved screen is usually the center of the screen. When the user deviates from this center position, the content on both sides of the screen may be deformed or distorted. This is because the design of the curved screen makes the edge part farther away from the user's eyes than the middle part, resulting in a narrower viewing angle, which leads to a decrease in the display effect of the display screen when the user deviates from this center position.

[0004] After searching, the Chinese patent publication number CN219473186U discloses a curved LCD screen. Although the design of this screen can improve the overall practicality of the curved LCD screen compared with the existing curved LCD screen, in many scenarios, such as conference rooms, classrooms, public corridors, etc., if the screen is not used or passed by, it will remain on, which will lead to unnecessary energy consumption. At the same time, in some security monitoring scenarios, if the screen cannot be turned on in time, the real-time monitoring of important security events may be missed, increasing security risks.

[0030] The present invention provides a curved liquid crystal display screen and a manufacturing method thereof. The present invention has the following beneficial effects:

[0031] (1) This curved liquid crystal display screen and its manufacturing method, in order to achieve automatic adjustment of the display screen angle according to the position of the viewer, uses infrared sensors and cameras to capture infrared radiation emitted by the human body and identify the position and movement of the human body. The data from these sensors are sent to the microprocessor, and the data processing unit in the microprocessor analyzes these data to determine the relative position of the viewer and the display screen. Subsequently, the control logic unit calculates the angle that needs to be adjusted based on these data to ensure that the viewer can see the best image. The microprocessor generates corresponding control instructions and sends them to the controller through the driver circuit board. The controller then converts these instructions into physical actions, such as driving the motor and the electric telescopic rod, so that the position and angle of the display screen can be automatically adjusted, thereby improving the user's viewing experience.

[0032] (2) A curved liquid crystal display screen and its manufacturing method. The signal processing unit in the power management module controls the power state of the display screen according to the signal of the infrared sensor. If a human body leaves, a timer starts timing. If the set time threshold is exceeded, the signal processing unit receives a feedback signal and then turns off the display screen to save energy. When the infrared sensor detects a human body again, the timer is reset and starts timing again, and the display screen is turned on again. This design allows the display screen to automatically turn off when no one is around and automatically turn on when someone approaches, effectively reducing energy waste and lowering energy consumption, which is in line with the development trend of green environmental protection.

[0033] (3) This curved liquid crystal display screen and its manufacturing method can ensure that each pixel on the display is precisely manufactured and positioned through precise photolithography and etching technology, thereby ensuring the clarity and resolution of the image. By adopting a high-density TFT array, each pixel has independent transistor control, so that the display screen can achieve higher resolution and clarity, presenting a more delicate image. In addition, through the combination of liquid crystal materials and TFT technology, the display screen has a wider viewing angle, and the user can get a good visual experience when viewing the screen at different angles.

[0034] Thus, the problem that the best viewing angle of the existing liquid crystal display screen is limited and the energy consumption is large during use is solved. BRIEF DESCRIPTION OF THE DRAWINGS

An alignment layer (20) is coated on the glass substrate, and the liquid crystal molecules are arranged in a specific direction by friction or chemical methods. A sealant is applied to the edges of the two glass substrates (16), and then they are bonded together to form a closed liquid crystal box, and the liquid crystal material is injected into the liquid crystal box. S03. Back-end module assembly, assembling the liquid crystal unit completed by the Cell process with other components, such as the backlight module (25), the driver circuit board (26), and the polarizer (24) into the final display product, pressing the driver IC and the glass substrate of the liquid crystal unit to form an electrical connection, assembling the backlight source assembly with the liquid crystal unit to provide uniform background light, and performing performance tests on the completed display, including brightness, contrast, and color, before packaging.
