4results about How to "Improve viewing angle characteristics" patented technology

This application discloses a driving method and driving system for a display panel, as well as a display device. The display panel includes multiple pixels, each pixel including a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The driving method includes: acquiring image information of an initial image, the image information including initial grayscale values ​​corresponding to three sub-pixels of at least one pixel, each initial grayscale value corresponding to a target grayscale value, the target grayscale value including a first target grayscale value and a second target grayscale value, the magnitude of the initial grayscale value being between the first target grayscale value and the second target grayscale value; determining whether at least three initial grayscale values ​​are all equal; if not, calculating the grayscale difference between the maximum value among the at least three initial grayscale values ​​and the initial grayscale value corresponding to a sub-pixel of at least one other color under preset conditions; acquiring the number of sub-pixels displayed with the initial grayscale value and the number of sub-pixels displayed with the target grayscale value based on the grayscale difference, so as to display a target image.

Provided is a liquid crystal display device capable of achieving high-speed response, high transmittance and contrast, and excellent viewing angle characteristics in both rising and falling. The liquid crystal display device performs color display in a plurality of subframe periods included in one frame period by field sequential driving, and includes: a liquid crystal display panel; a light source that irradiates the liquid crystal display panel with light of a plurality of colors; and a controller that drives the light source so that light of the plurality of colors is irradiated to the liquid crystal display panel in time division, the liquid crystal display panel successively having: a first substrate having a pixel electrode, a first alignment film, a liquid crystal layer, a second alignment film, and a second substrate having a common electrode, the liquid crystal layer having a first domain and a second domain in which alignment vectors are different from each other when no voltage is applied, when the alignment vectors are defined with a long axis end portion of the first substrate side of the liquid crystal molecules as a start point and a long axis end portion of the second substrate side as an end point.

The application provides a display panel and a display device. The display panel comprises: a color resistance layer, the color resistance layer comprising a plurality of color resistance unit groups arranged in sequence at intervals, each color resistance unit group comprising a plurality of color resistance units arranged in an array, the color resistance units being configured to transmit light; and a light transmission layer, the light transmission layer being arranged adjacent to a light exit side of the color resistance layer, the light transmission layer comprising a substrate and a plurality of diffusion groups arranged at intervals, the substrate being arranged opposite the color resistance layer, the plurality of diffusion groups being arranged on a side of the substrate away from the color resistance layer, each diffusion group comprising a plurality of diffusion portions, the diffusion portions being protruding or recessed from the substrate, and the diffusion portions being arranged at least partially opposite the color resistance units; when the display panel is in operation, light is incident on the light transmission layer via the color resistance layer, and then exits the display panel via the light transmission layer to a display surface of the display panel, the light has a first exit range via the color resistance layer, and the light has a second exit range via the light transmission layer, the second exit range being larger than the first exit range, thereby improving the display effect of the display panel at a side view angle.

An optical film and an electronic device including the optical film are disclosed. The optical film includes: a substrate portion; and a plurality of protrusions disposed on a surface of the substrate portion. Each of the plurality of protrusions includes: a first portion extending in a first direction parallel to the thickness direction of the substrate portion; and a second portion connected to the first portion and extending relative to the first direction at a first angle of inclination, wherein the first angle of inclination is an acute angle.
