The present invention belongs to the field of display technology, in particular to a power supply control method for display device and a display device. The power supply control method for a display device comprises: acquiring images of a room where the display device is located; judging whether there is any person in the room; when determining that there is a person in the room, further recognizing an action state of the person in the room and judging whether the person in the room has a demand of watching the display device; according to a result of judging that there is no person in the room or that the person in the room has no demand of watching, cutting power supply of the display device off.

Power supply control method for display device and display device

A liquid crystal display (LCD) substrate, comprising: at least one pattern region; and a cutting region around the at least one pattern region, wherein a piezoelectric thin film is formed in the cutting region, and each end of the piezoelectric thin film is connected with a lead.

LCD substrate and LCD panel

A mask plate comprises a light transmitting region; a light absorbing region; and a light reflecting region provided in the light absorbing region on one side of the mask plate. An exposing method using the mask plate comprises placing a first substrate coated with a first photosensitive resist layer under and parallel to the mask plate; having first light vertically strike on an upper surface of the mask plate from above, pass through the light transmitting region of the mask plate, and strike on the first photosensitive resist layer; placing a second substrate coated with a second photosensitive resist layer under and parallel to the mask plate; and having second light reflected by the lens device onto the surface of the mask plate where the light reflecting region is provided, then reflected by the light reflecting region and strike on the second photosensitive resist layer.

Mask plate and exposing method

A light guide plate used for an LED backlight source. The LED backlight source comprises a plurality of LED lamps. The light guide plate comprises a light guide plate body (). The light guide plate body () is provided thereon with a plurality of dots (), and there is a light guide region in the light guide plate body (). In the light guide region, the diameters of the dots in the same dot row progressively increase from the middle to either side, and diameters of the dots in the same dot column progressively increase in the direction away from the LED lamps.

Light guide plate, backlight source and liquid crystal display device

An exposure apparatus comprises: a loading stage for supporting a substrate; a mask plate parallel to the loading stage and above the loading stage, the mask plate including a light transmitting region and a light absorbing region on its lower surface, a light reflecting region being provided in the light absorbing region; a lens device provided between the mask plate and the loading stage; a first illumination light source, light from which vertically striking on the upper surface of the mask plate from above, passing through the mask plate and striking on the loading stage via the lens device; a light reflecting device provided in the lens device; and a second illumination light source, light from which being reflected onto the lower surface of the mask plate by the light reflecting device located in the lens device, the light being reflected by the light reflecting region on the lower surface of the mask plate and striking on the loading stage via the lens device.
