Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] An embodiment of the present application provides a display panel, referring to figure 1 , the display panel includes: a stacked display substrate 10 and a birefringent module 11, the birefringent module 11 is arranged on the light-emitting side of the display substrate, the birefringent module 11 has at least a peep-proof state, and the birefringent module 11 is configured as a peep-proof In this state, the light incident on the birefringent module 11 is birefringent to obtain the first light emitted along the first direction and the second light emitted along the second direction.

[0030] Wherein, the display substrate 10 may be flat or curved.

[0031] The display substrate 10 may be an LCD (Liquid Crystal Display, liq...

Abstract

The present application provides a display panel and a display device. The display panel includes: a stacked display substrate and a birefringent module, the birefringent module is arranged on the light-emitting side of the display substrate, and the birefringent module has at least In the anti-peeping state, the birefringent module is configured to perform birefringence on the light incident on the birefringent module in the anti-peeping state to obtain the first light emitted along the first direction and the first light emitted along the second direction of the second ray. By setting a birefringence module on the light-emitting side of the display substrate, the birefringence of the light emitted by the display substrate can be realized, and the light emitted in the first direction and the second direction can be obtained respectively, so as to realize dual-view display and anti-peeping at other viewing angles, which can be applied to Double shared area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the existing technology, mobile phones, tablet computers, TVs and other display devices mostly use wide viewing angle screens, and few manufacturers have added anti-peeping related technologies, which cannot meet the privacy needs of users, and information leakage incidents have increased frequently in recent years. With the enhancement of corporate and personal confidentiality protection awareness, there is a great market demand for the anti-peeping technology of display equipment. [0003] When handling business in the bank, it is necessary for the staff and the service personnel to obtain information one-on-one while preventing others from peeking at important information from other perspectives. Therefore, dual-view sharing is required, and other perspectives are protected from peeping. In additi...
