Abstract
A display device and a method of manufacturing the display device are provided. The display device includes a first display layer disposed on a surface of a display substrate and including a display element, a power supply unit that supplies a power signal to the display element, and a signal controller that supplies an image signal to the display element. The display element includes a base member, a pixel disposed on a surface of the base member, a driving circuit that provides a pixel driving signal to the pixel, a first transreceiver that receives the power signal and transmits the power signal to the driving circuit, and a second transreceiver that receives the image signal and transmits the image signal to the driving circuit.
Claims20
A display device comprising:
- a first display layer disposed on a surface of a display substrate and including a display element;
- a power supply that supplies a power signal to the display element;
- and
- a signal controller that supplies an image signal to the display element,
- wherein the display element includes:
- a base member;
- a pixel disposed on a surface of the base member;
- a driving circuit that provides a pixel driving signal to the pixel;
- a first transreceiver that receives the power signal and transmits the power signal to the driving circuit;
- and
- a second transreceiver that receives the image signal and transmits the image signal to the driving circuit, and
- wherein the driving circuit includes:
- a power storage circuit that stores the power signal and outputs a first voltage signal;
- and
- a voltage control circuit that generates a second voltage signal and a third voltage signal based on the first voltage signal.
A method of manufacturing a display device, comprising:
- preparing a display substrate including a display area and a non-display area adjacent to the display area;
- dispersing display elements in a fixing material to form a mixture;
- and
- applying the mixture on a surface of the display substrate in the display area,
- wherein the method includes:
- forming a base member for each of the display elements;
- forming a pixel on the base member;
- forming a driving circuit that generates a pixel driving signal based on a power signal and an image signal and provides the pixel driving signal to the pixel;
- forming a first transreceiver that provides the power signal to the driving circuit;
- and
- forming a second transreceiver that provides the image signal to the driving circuit,
- wherein the driving circuit includes:
- a power storage circuit that stores the power signal and outputs a first voltage signal;
- and
- a voltage control circuit that generates a second voltage signal and a third voltage signal based on the first voltage signal.
A display device comprising:
- a first display layer disposed on a surface of a display substrate and including a display element;
