Problems solved by technology

However, due to the structure of the anti-peeping film such as figure 1 As shown, it includes a light-transmitting part 11 and an opaque part 12, so that part of the light that hits the light-proof part 12 cannot be transmitted, so that the light transmittance of the display screen is greatly weakened, which affects the user experience.

Abstract

A display device and a light source are provided. The display device includes a display panel and a first photonic crystal layer arranged at a light-emitting side of the display panel. The first photonic crystal layer is configured to enable incident light to exit along a Z direction, the Z direction being a thickness direction of the first photonic crystal layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a light source. Background technique [0002] With the development of society and the enrichment of material conditions, the combination of electronic equipment and people's life and work has become more and more close. Nowadays, there are more and more types of electronic devices, such as desktop computers, laptop computers, mobile phones, e-book readers, etc. However, while electronic devices provide people with many conveniences, they may also cause the leakage of personal information. [0003] For example, users often use the above-mentioned electronic devices in some public places, such as Internet cafes, subways, buses, etc., and the display screens of ordinary electronic devices have a relatively large viewing angle, which is very important for the confidentiality of personal information security. Adverse. [0004] The existing anti-peep di...
