The invention discloses a folding display device and display equipment, and belongs to the field of a display technology. The folding display device comprises a support backboard and a display screen which is arranged on the frontage of the support backboard; the support backboard comprises a first bearing part and a second bearing part, wherein the first bearing part and the second bearing are connected in a folding way to be bent to the back of the support backboard; one end of the display screen is fixedly connected with the first bearing part, and the other end of the display screen is connected to the second bearing part in a sliding manner; the display screen is longer than the support backboard, one end of the display screen protrudes to the back of the second bearing part and covers the terminal of the second bearing part. According to the folding display device, the single-faced display and half-screen double-faced display can be realized at the same time, the problems that a flexible screen in the folding state is longer than the equipment in the horizontal expanding state can be effectively solved, and the damage on the screen can be prevented.

Method and device for generating gray scale correction table of curved surface display screen

The embodiments of the present invention disclose a method and a device for generating a gray scale correction table of a curved surface display screen, which relate to the field of image display and are used for improving the display uniformity of the curved surface display screen and then promoting the display effect of the curved surface display screen. In the embodiments, the method comprises the steps of defining an actual brightness table for expressing the actual brightness value of each pixel unit under a preset gray scale; defining a target brightness table for expressing the target brightness value to be arrived at by each pixel unit under the preset gray scale according to the actual brightness value mean of a plurality of sampling pixel units; for a random pixel unit in the curved surface display screen, comparing the difference between the actual brightness value and the target brightness value of the pixel unit under the preset gray scale, and calculating the corresponding gray scale correction value of the pixel unit under the preset gray scale according to the comparison result and a gamma curve corresponding to the area where the pixel unit is located in the curved surface display screen; and generating the gray scale correction table corresponding to the pixel unit, thus solving the above problems.
