The embodiment of the invention discloses a display device and a driving method thereof, and electronic equipment. The driving method of the display device comprises the following steps: determining adark display area and a bright display area of a display function area according to a picture to be displayed of a display panel, wherein the dark display area comprises a black display area and a boundary display area, and the boundary display area is located between the black display area and the bright display area; and when the display panel displays the picture to be displayed, controlling apixel gray scale value of the boundary display area to be greater than 0 and less than a pixel gray scale average value of the bright display area adjacent to the boundary display area, and adjustingthe backlight brightness La corresponding to the boundary display area, wherein La is greater than 0 but less than Lb, and Lb is the backlight brightness of a backlight partition corresponding to thebright display area adjacent to the boundary display area. According to the driving method of the display device provided by the embodiment of the invention, the boundary display area serves as the brightness transition of the bright display area and the black display area, so that the bright and dark display areas gradually become dark, so that the display transition of the display picture is soft, good visual effect is achieved, and the display power consumption is not greatly increased.

The invention relates to the technical field of communication, and especially relates to a method and an apparatus for correcting the physique posture in the remote teaching process. The method of the invention comprises the following steps: acquiring physique posture characteristic data of a current target object through a first image capture device; comparing the physique posture characteristic data with standard physique data and calculating the deviation value; and when the deviation value is greater than a preset threshold, outputting the result of comparison to remind the current target object to correct the physique posture. The invention provides a method for correcting physique posture by acquiring physique posture characteristic data through the first image capture device, and aims to solve the problem that some standardized actions made by a target object are neither standardized nor accurate and correct non-standardized sitting postures. In addition, in order to protect the personal vision health, a screen can be turned off when a person is close to the screen under the help of the image capture device, a more user-friendly design is provided, and the user experience is improved.

The invention discloses an image rendering method and a display device. According to the image rendering method, when a display panel is driven to perform imaging displaying, image pixels which correspond with the left boundary of to-be-displayed image information are displayed through the front three sub-pixel units in each line of sub-pixel units of the display panel; the image pixels which correspond with the right boundary of the to-be-displayed image information are displayed through the last three sub-pixel units in each line of sub-pixel units of the display panel; namely the left boundary of the display panel displays the left boundary of the to-be-displayed image information through the front three rows of sub-pixel units, and the right boundary of the display panel displays the right boundary of the to-be-displayed image information through the last three rows of sub-pixel units; and the left boundary and the right boundary of the display panel perform image displaying through same number of sub-pixel units, thereby reducing display brightness difference between the left boundary and the right boundary of the display panel and improving image display effect.

A display panel, a display device, and a terminal device, which can achieve a high image quality by decreasing deterioration of the image quality that may be caused due to combining a reflection plate including an uneven structure with an image distributing device, are provided. The display panel includes a lenticular lens for distributing light emitted from each of pixels towards different directions from each other along an arranging direction (a first direction) of a pixel for displaying an image for a first viewpoint and a pixel for displaying an image for a second viewpoint within a pixel unit, wherein a reflection plate including an uneven structure is formed in each of the pixels, and a layout pattern of the uneven structure on the reflection plate is different to the lenticular lens.

The invention discloses a 3D display device. A first optical grating layer with poriform light-transmitting areas in array arrangement is arranged on the light-emitting side of a display panel; and a second optical grating layer with light-transmitting areas in array arrangement is arranged on the first optical grating layer. by adjusting the sizes of overlapped areas of the light-transmitting areas of the first and second optical grating layers to or not to meet the conditions of pinhole imaging, switch between a 2D display state and a 3D display state is realized; and in the 3D display state, the overlapped area of projections of each pair of poriform light-transmitting areas on the display panel is adjusted to achieve an area with the pin hole imaging condition of being smaller than one pixel unit and realize angle adjustment of emergent light of sub pixel units in the display panel, so that the effect that left eye images and right eye images are collected in different positions is achieved to realize naked-eye 3D display. Therefore, compared with shielding stripes, the 3D display device reduced shielding of light, avoids reducing display brightness and realizes high-brightness 3D display.

The invention discloses a still image ghost shadow prevention method based on a playing data stream, which comprises the following steps: when a current television starts an application, acquiring anoriginal playing data stream of the television; determining whether a playing picture of the television is static or not according to the obtained original playing data stream; and if it is confirmedthat the playing image of the television is static, reducing the screen display brightness of the television to prevent image ghost shadow. The invention further discloses a television and a storage medium. According to the invention, the television screen brightness is reduced by detecting the situation that the television playing picture is static, image ghost shadow is avoided by reducing the television screen brightness, and the user experience is improved.

The invention discloses a display panel and a preparation method thereof. The display panel comprises a liquid crystal box and a peep-proof structure, wherein the peep-proof structure comprises a glass substrate and a black matrix layer, and the black matrix layer is arranged on the side, away from the liquid crystal box, of the glass substrate; and a plurality of black matrixes are uniformly distributed in the black matrix layer. According to the peep-proof display panel, the peep-proof effect is achieved, meanwhile, the number of film layers is reduced, and the production cost is reduced.
