Abstract
The invention discloses a display panel, a display device and a driving method. By providing an optical interference layer, when the first transparent electrode and the second transparent electrode are loaded with a first reference voltage, the first transparent electrode and the second transparent electrode A semi-transparent and semi-reflective film layer is formed on the opposite surface to form a resonant cavity. The resonant cavity can perform interference selection on the light emitted by the corresponding sub-pixel and incident on the optical interference layer: the light within a certain wavelength range and perpendicular to the optical interference layer is coherent and constructive, which is equivalent to passing through the optical interference layer with a high transmittance. An optical interference layer to enable the user to see the display. Light within the same wavelength range and non-perpendicularly incident on the optical interference layer is coherent and destructive, which is equivalent to passing through the optical interference layer with a lower transmittance or even not passing through it. In this way, the light emitted at a large angle can pass through the optical interference layer less or even cannot pass through the optical interference layer, so that the light emitting angle of the display panel is smaller, so as to achieve the purpose of anti-peeping.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method. Background technique [0002] The light output angle of the display is usually relatively large, and a display with a large light output angle can bring a better experience to users in many applications. However, in personal mobile products, a large light angle may allow others to see the content browsed by the user, which may cause leakage of personal information or privacy. Contents of the invention [0003] An embodiment of the present invention provides a display panel, which can reduce the light emitting angle of the display panel. [0004] Therefore, an embodiment of the present invention also provides a display panel, including: an array substrate and a counter substrate disposed opposite to each other, and a plurality of sub-pixels, and also includes: an optical interference sensor located on the side of ...
