    摘要: A method and device for adjusting a display parameter, and a display device. An ambient brightness level is used as a criterion to adjust a brightness level of an intermediate gray level of a displayed image, such that a corresponding display parameter can be adjusted to be closer to the criterion within an appropriate allowable floating range, thereby providing a displayed image that is safe and comfortable for the eyes. The method comprises: detecting an ambient brightness level (101); determining an adjustment parameter of a display device corresponding to a preset condition, the preset condition comprising a difference between a brightness level of an intermediate gray level of the display device and the ambient brightness level being less than or equal to a preset brightness value (102); and adjusting, according to the adjustment parameter, brightness levels of at least a portion of gray levels of the display device (103).

    摘要: A display substrate, a manufacturing method thereof, a display device, and a mask plate are provided. The display substrate includes: a base substrate including a display region and a peripheral region, the peripheral region including a first peripheral region and a second peripheral region; a first power voltage terminal located in the first peripheral region; a first power signal line located in the display region and configured to be electrically connected with the first power voltage terminal; and a pixel defining layer, an edge of the pixel defining layer including a slope. The second peripheral region includes a first sub-region and a second sub-region located on a side of the first sub-region away from the first power voltage terminal, and an average slope angle of the slope located in the first sub-region is greater than an average slope angle of the slope located in the second sub-region.

    摘要: The present disclosure relates to a backlight module. The backlight module is configured for use in a transparent display device and comprises: an optical splitter; and a light source arranged at a side of the optical splitter and emitting light towards the optical splitter. The optical splitter is configured to split light emitted from the light source into a first light beam and a second light beam, wherein the first light beam is configured for supplying backlight, and the second light beam is configured for illuminating background behind the optical splitter. The present disclosure also relates to a transparent display device, comprising the above described backlight module; as well as an array substrate and a color film substrate arranged in front of the backlight module.
