Abstract: A display apparatus includes a housing; a back plate on the housing; a metal bezel clamped with the back plate at a side of the back plate; a display module and a display driving board on a side of the back plate away from the housing. An insulating material layer is provided between the back plate and the display driving board, which directly increases an impedance of a path for static electricity from the back plate to the display driving board; a side of the display module is fixed to the metal bezel by an insulating member, indirectly increasing an impedance of a path of the static electricity entering the display driving board through the display module. Therefore, most of the static electricity is discharged through other paths with small impedance, so that the static electricity less enters a signal ground plane.

Abstract: This disclosure relates to a liquid crystal display and a display device. A plurality of photosensitive detectors is arranged in the frame region of the liquid crystal display panel. Light intensity distribution in the display region is estimated by a light intensity estimation module based on the light intensity detected by each photosensitive detector. Light intensity in a position corresponding to each light emitting pixel of the backlight source is determined based on the light intensity distribution in the display region estimated by the light intensity estimation module. Depending on the determined light intensity in a position corresponding to each light emitting pixel of the backlight source, luminance of the light emitting pixel in this corresponding position is controlled by a backlight driving circuit.
