Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to a bistable cholesteric liquid crystal display structure. Background Technology

[0002] Traditional liquid crystal displays (LCDs) typically use liquid crystal molecules in a single stable state to control the transmission or reflection of light, which limits the display's resolution and contrast. In recent years, the emergence of bistable liquid crystal materials has changed this situation. These materials can change their optical properties in two different states, thereby achieving higher resolution and better viewing angles. Cholesteric bistable liquid crystal materials are a special type of bistable liquid crystal material with excellent cholesteric phase alignment characteristics, enabling highly controllable bistable liquid crystal behavior. Compared to traditional bistable liquid crystal materials, cholesteric bistable liquid crystal materials have lower response times and faster switching speeds, which can improve the refresh rate and response speed of displays.

[0003] According to CN202420913645.3, an erasable bistable cholesteric liquid crystal writing device includes a writing tablet and a stylus. The writing tablet includes a first electrical connection connector and a flexible bistable cholesteric liquid crystal display panel. The stylus includes a pen barrel shell, an erasing drive structure, an erasing control button, and a second electrical connection connector. The pen barrel shell is rod-shaped and divided into an upper segment and a lower segment that are detachably connected and arranged vertically. The erasing drive structure is located inside the pen barrel shell and can be electrically connected to the second electrical connection connector when they are connected to the first electrical connection connector, applying an erasing voltage to the bistable cholesteric liquid crystal display panel. The erasing control button is located in the pen barrel shell and is used to control the erasing drive structure to apply a global erasing voltage or a local erasing voltage to the bistable cholesteric liquid crystal display panel. This invention removes the erasing circuit structure from the writing tablet, making the writing tablet resemble paper in shape and thinner.

[0004] The existing device does not have a storage place for the stylus. In actual use, changes in lighting or different user heights may cause the current placement angle to not meet the user's needs well, resulting in poor user comfort.

[0005] Therefore, it is necessary to propose a bistable cholesteric liquid crystal display structure. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a bistable cholesteric liquid crystal display structure that has the advantages of being able to store a stylus and adjust the tilt angle of the display screen, thus solving the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a bistable cholesteric liquid crystal display structure, comprising a display screen, a base, and an L-shaped flip plate:

[0008] The base is rotatably connected to one side of the display screen. The back of the display screen has multiple slots. One side edge of the display screen has a limiting groove. The surface of the base has a through groove. The inner wall of the through groove is rotatably connected to a bracket. The L-shaped flip plate is set on one side of the base. A protrusion is fixedly connected to the side of the top of the L-shaped flip plate. The bottom side of the L-shaped flip plate has a second side groove. The surface of the base near the L-shaped flip plate has a first side groove. A spring block is slidably inserted into the inside of the first side groove. The spring block matches the model and specifications of the second side groove.

[0009] Preferably, the base has a storage compartment on its side, and a stylus is placed inside the storage compartment.

[0010] Preferably, the bracket matches the model and specifications of the multi-level card slot.

[0011] Preferably, the limiting groove matches the model and specifications of the protrusion.

[0012] Preferably, one end of the spring block is fixedly connected to a spring, and the spring is fixedly connected to the inner wall of the side groove.

[0013] Preferably, a pressing block is slidably engaged inside the second side groove, a second spring is fixedly connected to one side of the pressing block, and the other end of the second spring is fixedly connected to the inner wall of the second side groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This bistable cholesteric liquid crystal display structure, comprising a display screen, a base, and an L-shaped flap, allows the display screen and base to overlap in normal mode. The stylus is placed inside the storage compartment for storage. A protrusion is inserted into a limiting groove, and the spring force of a pair of spring blocks ensures the sides of the spring blocks remain inserted into the second side groove, thus fixing the L-shaped flap to the side of the display screen and securing it to the base. To adjust the display screen's tilt angle, squeezing the squeezing block pushes the spring blocks, disengaging their ends from the second side groove. The L-shaped flap can then rotate, releasing the protrusion from the limiting groove, allowing the display screen to rotate. Finally, the bracket can be moved and engaged in a multi-level slot to support the display screen, improving user comfort. Attached Figure Description
