Abstract

A display driving circuit and display driving method for a display panel, and a display apparatus. In the display driving circuit (00), the duration in which a gating control signal transmitted by a display driver (03) to a gating circuit (02) is at a first level is less than the duration in which a source driving signal is transmitted to a pixel, and the time period in which the transmitted gating control signal is at the first level is within the time period in which the source driving signal is transmitted, that is, the display driver (03) at least can transmit the gating control signal of the first level to the gating circuit (2), so that the source driving signal is transmitted to the pixel while or before a gating unit (021) in the gating circuit (02) controls a respective shift register unit (011) and the connected pixel to be communicated with each other. Thus, a load in the display panel can be prevented from varying with the on-off of the source driving signal, thereby solving the problem of luminance difference at the boundary between a high-refresh-rate display zone and a low-refresh-rate display zone so as to ensure a better display effect of the display panel.

The display apparatus comprises: a liquid crystal diaphragm (2), wherein the liquid crystal diaphragm (2) comprises a plurality of liquid crystal units (20), and each liquid crystal unit (20) is configured to switch between a first state and a second state, the first state being used for transmitting light, and the second state being used for shielding light; and in the same moment, at least some of the liquid crystal units (20) in the liquid crystal diaphragm (2) are in the first state, and the other liquid crystal units (20) are in the second state; and a plurality of imaging assemblies (1), wherein the plurality of imaging assemblies (1) are located on the same side of the liquid crystal diaphragm (2), each imaging assembly (1) comprises an imaging lens group (11) and a signal detector (12), and the signal detector (12) is located on the side of the imaging lens group (11) that faces away from the liquid crystal diaphragm (2), and the signal detector (12) is used for receiving light transmitted through the liquid crystal diaphragm (2) and for converting an optical signal into an electrical signal. When different liquid crystal units (20) are in the first state, image points (S1, S2) corresponding to the same object point (S) are located at different positions of the signal detector (12), and thus the signal detector (12) can collect more complete direction information of the object point (S), so as to reconstruct stereoscopic information of the object point (S).

Abstract

Disclosed in the present disclosure are a reflective sheet, a light-emitting substrate, a backlight module and a display device, which can solve the problems of the reflective sheet easily bulging and detaching, and creasing under stress. The reflective sheet comprises: a light-reflecting layer, which comprises a plurality of first light-reflecting portions; and an adhesive layer, which comprises a plurality of first adhesive portions, wherein at least some of the first light-reflecting portions each comprise a first light-reflecting area and two second light-reflecting areas located on two sides of the first light-reflecting area; and the orthographic projection of a release layer on the first light-reflecting areas is disconnected from the orthographic projection of the release layer on the second light-reflecting areas, and/or each first adhesive portion comprises a first opening, and the orthographic projection of the first openings on the plane where the light-reflecting layer is located overlaps the first light-reflecting areas.
