Display panel

Abstract

The invention discloses a display panel. The display panel includes optical waveguides, wires, and a pixel array; the pixel array includes a plurality of pixel units; the pixel units are arranged in multiple rows and lines; each pixel unit includes a pixel electrode, a filtering unit, and an optical transistor, wherein the filtering unit is coupled to one of the optical waveguides, the optical transistor is electrically connected to one of the pixel electrodes and the wires, and the optical transistor is coupled to the filtering unit; the optical waveguides are used for transmitting an optical control signal; the wires are used for transmitting an electrical control signal; the filtering units are used for receiving a sub control signal from the coupled optical waveguides, and for selecting a certain optical signal as an input signal of the optical transistor according to the received sub control signal.

Description

technical field [0001] The present invention relates to a display panel, in particular to a display panel that transmits signals by light. Background technique [0002] Conventional display panels usually use electrical signals to transmit information, that is, to drive rows or columns of a pixel array with voltages or currents carrying driving data. Such a structure is convenient for the user to control the addressing of the pixel array. However, with the increase of the resolution and the increase of the panel size, the distance between the elements in the display panel is also shortened, resulting in many non-ideal effects. For example, the increase of the parasitic capacitance and parasitic resistance of the substrate of the active element in the display panel causes problems such as signal attenuation or signal delay, resulting in an output or read signal error. In addition, the increase in resolution increases the number of traces, which also limits the space for per...
