Embodiment Construction

[0052] The designer found that the strip-shaped protrusions can improve the reflectivity of the reflector, but in the prior art, the strip-shaped protrusions arranged alternately in an orthogonal manner have higher reflectivity at the orthogonal azimuth angles, but have higher reflectivity at other azimuth angles. lower. Designers are looking for a new solution to design reflectors using strip-shaped protrusions to solve the above problems while ensuring high reflectivity.

[0053] The present invention provides a reflection device, the reflection device includes a reflection layer, the reflection layer includes protrusions, and the protrusions are strip-shaped protrusions extending around a central direction. Since the protrusions are strip-shaped protrusions, the actual effective reflection area has a relatively large area and high reflectivity; meanwhile, the strip-shaped protrusions extend around a central direction, and the reflective device can be positioned at multiple ...

Abstract

The invention relates to a reflection device. The reflection device comprises a reflection layer. The reflection layer comprises bulges. The bulges are strip bulges extending around a center direction. The reflection device provided by the invention has high reflectivity in all azimuths and high uniformity. Moreover, in the reflection device provided by the invention, if the widths of the strip bulges or the spaces between the strip bulges are different, or both the widths of the strip bulges and the spaces between the strip bulges are different, the interference phenomenon of light can be avoided so as to avoid a poor visual effect. The invention also provides a liquid crystal display device, which comprises a plurality of pixel units. Each pixel unit comprises a reflection region. The reflection device is adopted in each reflection region.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and in particular designs a reflection device used in the field of liquid crystal display and a liquid crystal display device using the reflection device. Background technique [0002] According to the different light sources used, liquid crystal displays can be divided into transmissive liquid crystal displays with built-in backlight, reflective liquid crystal displays that reflect ambient light, and transflective liquid crystal displays that combine transmission and reflection. [0003] The reflective liquid crystal display, and the reflective part in the transflective liquid crystal display, has the advantage that the contrast of the reflected light is not affected by the ambient light, so the liquid crystal display can maintain the Good readability. The reflective liquid crystal display and the transflective liquid crystal display include a reflective device for reflecting incident ligh...
