Liquid crystal lens, display device and curved surface display method

Abstract

The invention discloses a liquid crystal lens, a display device and a hook face display method and relates to the display field. Hook face display can be achieved, manufacturing is easy, cost is low, service life is long, and occupied physical space is small. The liquid crystal lens is used for being attached to the outer side of a flat panel display device to realize the hook face display effect and comprises multiple lens units. Each lens unit comprises a liquid crystal layer, an orientation layer, a first electrode and a second electrode, wherein the first electrode and the second electrode are used for driving the liquid crystal layer. The lens units are independently driven so that the refractive indexes of the lens units arranged along an equivalent hook face can become larger gradually from a position corresponding to the optimal observation point to two sides.

Description

technical field [0001] The invention relates to the display field, in particular to a liquid crystal lens, a display device and a curved surface display method. Background technique [0002] Most of the current display devices are flat display devices. Since the eyeball is spherical, viewing a pure flat display screen is actually distorted, and the larger the screen size, the more obvious it is. If the display screen is designed according to the curvature of the retina, so that the display screen is completely parallel to the retina, the most realistic images can be transmitted to the brain. If the screen is designed as a curved surface, and the curvature of the curved surface meets the requirements of ergonomics, that is, it conforms to the spherical characteristics of the eyeball, so that every point on the screen can reach the eye at the same distance, such as figure 1 As shown, better viewing angles can be achieved on the left and right sides, the visual distortion at t...

Problems solved by technology

[0003] However, if a curved display is to be realized, for liquid crystal display products, the bending of the glass substrate is relatively easy, but the bending of the backlight module is very difficult; at the same time, it is difficult to ensure that the brightness of each pixel is consistent after bending the backlight module

Moreover, for the existing curved display products on the market, viewers can enjoy the best visual experience only when they are located at the 'sweet viewing point', and the curved display products cannot be hung against the wall as a whole, requiring a large physical space, and After a long time of use, some products may cause quality problems due to stress concentration, and the service life is short

Although OLED devices can realize flexible display and easy to achieve curved surface display effect, the current technology is still immature, with short service life and high cost, and further exploration and development are still needed
