PNLC negative liquid crystal display screen

Technical Field

The utility model belongs to the technical field of liquid crystal display, concretely relates to negative liquid crystal display of PNLC.

Background

The liquid crystal display is a flat thin display device, which is composed of a certain number of color or black and white pixels and is placed in front of a light source or a reflecting surface. Liquid crystal displays have low power consumption, are suitable for electronic devices using batteries, are a display type used in digital watches and many portable computers, and have a display technology that is changing day by day, and as the amount of information is increasing, people have increasingly demanded liquid crystal displays.

Among the prior art, LCD liquid crystal display in the trade all needs two-layer polaroid at the bottom of the wainscot just can show relevant content, after light enters into the polaroid, form the polarized light, the polarized light is when passing through the liquid crystal layer, add the voltage formation electric field because of liquid crystal by ITO at the bottom of the face, make relevant liquid crystal take place to twist reverse, so cause hiding or twisting of light, realize corresponding display effect, and do not paste these two-layer polaroid and can not see the display content promptly, thereby lead to liquid crystal display need paste two-layer polaroid just can show the content, greatly improve manufacturing cost.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a PNLC negative liquid crystal display screen, adopts PNLC negative liquid crystal through liquid crystal, solves the problem that the liquid crystal display screen needs the polaroid to display the content, realizes that the liquid crystal display screen can display the content without using the polaroid, greatly reduces the manufacturing cost, and effectively ensures the economic benefit.

The technical scheme provided by the embodiment of the application is as follows:

a PNLC negative liquid crystal display screen comprises a first glass substrate layer, a first glass coating layer, a first orientation layer, PNLC negative liquid crystal, a second orientation layer, a second glass coating layer and a second glass substrate layer which are sequentially connected from top to bottom, wherein frame glue is arranged on four sides of the PNLC negative liquid crystal, and the PNLC negative liquid crystal comprises prepolymers and liquid crystals which are uniformly distributed at intervals.

The PNLC negative liquid crystal is prepared by placing the uniformly and alternately arranged prepolymers and liquid crystals in an environment with the temperature of 24-30 ℃, and irradiating the liquid crystals for 600 seconds by using an ultraviolet lamp with the wavelength of 320-390nm and the light intensity of 30-50mw/cm, so that a polymer network stable liquid crystal is formed, and the display effect is transparent before voltage is not applied; when the driving voltage of more than or equal to 10V is applied to the upper electrode and the lower electrode, the display characters of the display screen are changed from being transparent to being in milk white display, and the non-display area is transparent.

Furthermore, the first orientation layer and the second orientation layer are vertical orientation layers, and through the arrangement, PNLC negative liquid crystal molecules can be arranged in the grooves without rubbing the orientation layers to form uniform grooves by a towel, so that the operation is simple and convenient, the manufacturing efficiency is improved, a stable orientation effect is provided for liquid crystals, and the good contrast of the liquid crystal display screen is ensured.

Furthermore, the vertical gap between the first glass substrate layer and the second glass substrate layer is 7-8 μm, and through the arrangement, the distance between the first glass substrate layer and the second glass substrate layer is suitable for injecting PNLC negative liquid crystal, so that the driving voltage of the liquid crystal display screen is effectively reduced, the power consumption is greatly reduced, the contrast of the liquid crystal display screen cannot be influenced due to the fact that the distance between the first glass substrate layer and the second glass substrate layer is too small, and good contrast of the liquid crystal display screen is effectively provided.

Further, frame powder is arranged in the frame glue.

Furthermore, a central powder is arranged in the PNLC negative liquid crystal.

The utility model has the advantages that:

the liquid crystal adopts PNLC negative liquid crystal, so that the problem that the liquid crystal display screen can display contents only by using the polaroid is solved, the liquid crystal display screen can display contents without using the polaroid, the manufacturing cost is greatly reduced, and the economic benefit is effectively guaranteed.
