Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a hybrid reflection structure. Background Technology

[0002] Liquid crystal displays (LCDs) are a technology that displays images based on the optical properties of liquid crystal materials. Liquid crystal molecules can change their alignment under the influence of an electric field, thereby controlling the transmission and blocking of light. Early LCDs were mainly passive matrix displays, which had slow response times and low contrast. With technological advancements, active matrix liquid crystal displays (AMLCDs) emerged, using thin-film transistors (TFTs) to precisely control the liquid crystal state of each pixel, greatly improving display performance.

[0003] Existing technologies have the following shortcomings: the folded edges and perforated designs of traditional reflective sheets easily lead to uneven light reflection, resulting in bright edges and other problems that affect the display effect. Furthermore, the light strips may shift during use due to a lack of effective fixation, affecting the backlight effect. Inaccurate installation between components can also affect the structural stability and functionality. Therefore, those skilled in the art have provided a hybrid reflective structure to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hybrid reflective structure. To achieve the above objective, this utility model provides the following technical solution: It includes a decorative strip, a liquid crystal display screen, a lower middle frame, a film, a diffuser plate, a reflective sheet, a top rod, a back plate, a light strip, and a back cover assembly. The reflective sheet adopts a non-folded edge design and does not eliminate bright edges through perforation. The reflective sheet has a planar structure without folds, a flat surface, and no perforations for eliminating bright edges. The reflective sheet is made of a material with high reflectivity to ensure uniform backlight reflection even without folds or perforations. This design allows for uniform reflection of light emitted from the light strip even without folds or perforations, providing a uniform backlight reflection effect for the liquid crystal display screen. This ensures the uniformity and stability of the display screen's backlight and avoids the uneven light problems that may be caused by folds or perforations.

[0005] Preferably, the diaphragm is disposed between the liquid crystal display screen and the diffuser plate. The diaphragm can further optimize and adjust the light, such as improving the color and contrast characteristics of the light. The diffuser plate is responsible for diffusing the light reflected from the reflector, distributing it more evenly across the entire back of the liquid crystal display screen, ensuring that all areas of the display screen receive uniform illumination, thereby improving the clarity and consistency of the display.

[0006] Preferably, the light strip is disposed between the reflector and the back plate, and the light strip is used to provide backlight for the liquid crystal display screen. Part of the light emitted by the light strip directly illuminates the reflector and provides backlight for the liquid crystal display screen after being reflected by the reflector; the other part of the light passes directly through components such as the diffuser plate to provide illumination for the display screen. In this way, sufficient light supply is ensured to meet the display requirements of the liquid crystal display screen.

[0007] Preferably, the top rod is disposed between the diffuser plate and the back plate to support the diffuser plate. Since the diffuser plate needs to be kept in a stable position to ensure uniform light diffusion, the supporting force provided by the top rod can prevent the diffuser plate from shifting or deforming due to its own weight or other external forces, thereby ensuring the stability of the light propagation path.

[0008] Preferably, the back cover assembly includes a fixing structure for securing the light strip, preventing displacement of the light strip during use. During device use, the light strip may shift due to vibration, collision, or other reasons, which can affect the uniformity and stability of the backlight. The fixing structure of the back cover assembly effectively restricts the position of the light strip, ensuring it remains in a predetermined position during normal operation, stably providing light to the reflector and LCD screen.

[0009] Preferably, the lower middle frame is provided with a mounting groove for installing the top rod. The size of the mounting groove is adapted to the top rod to ensure that the top rod is securely installed on the lower middle frame, thereby providing reliable support for the diffuser plate. At the same time, the lower middle frame also provides a certain framework support and protection for the entire hybrid reflective structure, ensuring that the components work together in a relatively stable environment.

[0010] Preferably, the hybrid reflection structure further includes a flexible circuit board for connecting the liquid crystal display screen and the external circuit. The flexible circuit board is disposed on one side of the lower middle frame. The flexible circuit board is responsible for transmitting the electrical signals provided by the external circuit to drive the liquid crystal display screen to work normally, ensuring that the display screen can accurately display the corresponding image or text information according to the received signal, thereby realizing the functional integrity of the entire display system.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the reflective sheet adopts a non-folded and non-perforated design. It uses a high reflectivity material to ensure that it can still provide a uniform backlight reflection effect without folding or perforation. This solves the problem of uneven backlight caused by unreasonable reflective sheet structure, enabling the LCD screen to obtain more uniform and stable illumination and improve display clarity and consistency.

[0013] 2. In this utility model, the fixing structure in the back cover assembly effectively prevents the light strip from shifting, and the reliable support of the top rod on the diffuser plate ensures its stable position, avoiding uneven light and abnormal display caused by component displacement or deformation, thus improving the stability and reliability of the entire structure.

[0014] 3. In this utility model, an installation groove adapted to the top rod is provided on the lower middle frame, which ensures the stable installation of the top rod and provides stable support for the diffuser plate. This precise installation design optimizes the cooperation between the components and solves the problems of structural loosening and component displacement that may be caused by improper installation, thus ensuring the normal operation and performance of the hybrid reflection structure.

Since the diffuser plate 5 needs to be kept in a stable position to ensure uniform light diffusion, the supporting force provided by the top rod 7 can prevent the diffuser plate 5 from shifting or deforming due to its own weight or other external forces, thereby ensuring the stability of the light propagation path. The back cover assembly 10 includes a fixing structure for fixing the light strip 9 to prevent the light strip 9 from shifting during use. During the use of the device, the light strip 9 may shift due to vibration, collision, etc., which will affect the uniformity and stability of the backlight. The fixing structure of the back cover assembly 10 can effectively limit the position of the light strip 9, ensuring that it always stays in the predetermined position during normal operation, stably providing light to the reflector 6 and the liquid crystal display 2.

[0028] Working Principle: This hybrid reflection structure is mainly used to provide uniform and stable backlight for the LCD screen to ensure good display effect.
