Display panel, display device and signal transmission device
First Claim
1. A display panel, comprising:
- an array substrate;
an opposed substrate arranged opposite to the array substrate;
a circuit board, disposed on a side of the array substrate away from the opposed substrate;
a driving circuit, disposed on a side of the array substrate close to the opposed substrate;
a light emitter, disposed on a side of the circuit board close to the array substrate and electrically connected with the circuit board, in which the light emitter includes a light emitting surface which faces the array substrate; and
a light receiver, disposed on a side of the array substrate close to the opposed substrate and directly and electrically connected with the driving circuit, in which the light receiver includes a light receiving surface which faces the light emitter,wherein the light receiver is configured to convert light intensity information received by the light receiving surface into an electrical signal and output the electrical signal to the driving circuit,the light receiver provides the electrical signal to the driving circuit, the electrical signal is a signal which drives the display panel to display image information,wherein the display panel further comprises a collimator, and the collimator includes a second focus which is disposed on the light emitting surface, and the collimator is selected from a group consisting of a microlens, an aspherical lens and a spherical lens, the collimator is disposed at a light-exiting side of the light emitter, the collimator is disposed between the light emitter and the light receiver, and a distance of the collimator and the light emitter is an object focal length, andwherein the display panel further comprises a moving unit which is configured to drive the light emitter to do translational motion during displaying an image.
