The embodiments of the present disclosure provide a circuit for removing residual image after power-off, a method for driving the circuit, and a display apparatus. The circuit comprises a comparator, a control circuit and an output circuit. The comparator is configured to output a high level voltage when a voltage at its non-inverting terminal is higher than a voltage at its inverting terminal, or output a low level voltage when the input voltage at its non-inverting terminal is lower than or equal to the input voltage at its inverting terminal. The control circuit is configured to align a voltage at the control node with a voltage at the second level terminal when the comparator outputs the high level voltage, and align the voltage at the control node with a voltage at the third level terminal when the comparator outputs the low level voltage. The output circuit is configured to output a voltage of the fourth level terminal at the signal output terminal when the voltage at the control node is the voltage at the third level terminal, and output a voltage of the fifth level terminal at the signal output terminal when the voltage at the control node is the voltage at the second level terminal.

A circuit arranged in a gate drive area on a display panel comprises control lines. Each control line is connected with multiple gate lines, and the gate lines connected with each control line are distributed at intervals on the display panel. A switch-on level can be provided sequentially to the control lines in a preset time interval when the display panel is being shut down. The circuit mitigates or otherwise eliminates a shutdown afterimage phenomenon and also avoids delivery of a relatively large instantaneous current generated at shutdown.

Circuit and display device

Provided are display screen and method for manufacturing the same. The display screen includes a first substrate, a second substrate and a liquid crystal layer arranged between the first substrate and the second substrate; the first substrate includes a base substrate, an optical module arranged on the base substrate, and a plurality of pixel units directly arranged on the optical module; and the second substrate includes an array substrate.

Display screen and method for manufacturing the same

The invention relates to a field of display technique. There is disclosed a circuit for eliminating shutdown afterimages of a display. By designing a circuit capable of generating voltages for tuning on TFTs in a time-division way, it is realized that when the display screen shuts down, not only the significant discontinuous differences of pictures are ensured to be not perceived by human eyes so as to eliminate the shutdown afterimages, but also such a problem can be avoided that the circuitry in the panel is burned out by the overlarge instantaneous current caused by the simultaneous turning on of all the TFTs at the moment of shutdown.
