A transmitter includes a controller, configured to generate a control voltage corresponding to a pattern of the change in an amount of light emitted wherein the pattern in which one of a plurality of amounts of light emitted occurs indicates a signal to be transmitted, and a reflector that reflects sunlight. The transmitter also includes a liquid crystal board that receives reflected light that is sunlight reflected by the reflector and transmits the signal to a receiver by changing the amount of light emitted toward the receiver according to the control voltage. The liquid crystal board changes the reflected light passing through rate to a high passing through rate when one of the plurality of the amounts of light emitted occurs, and changes the reflected light passing through rate to a low passing through rate when another one of the plurality of amounts of light emitted occurs.

Embodiments of the present disclosure provide a display substrate and a manufacturing method thereof, a display driving method and a display device. The display substrate includes: a transparent base; a bidirectional light emitting element array emitting light in a first direction and a second direction perpendicular to the transparent base; a first variable grating array transmits or blocks the light emitted by odd-numbered columns of bidirectional light emitting elements in the first direction; a second variable grating array transmits or blocks the light emitted by odd-numbered columns of bidirectional light emitting elements in the second direction; a third variable grating array transmits or blocks the light emitted by even-numbered columns of bidirectional light emitting elements in the first direction; and a fourth variable grating array transmits or blocks the light emitted by even-numbered columns of bidirectional light emitting elements in the second direction. Multiple display modes can be realized.

A display assembly includes a display device, a first clamping plate and a second clamping plate. The display apparatus has at least one display area, and the first clamping plate and the second clamping plate are disposed on two opposite sides of the display device in a thickness direction thereof.
