DISPLAY APPARATUS AND CONTROL METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18098528 titled 'DISPLAY APPARATUS AND CONTROL METHOD THEREFOR
Simplified Explanation
The patent application describes a display device that includes a display panel with a pixel array consisting of inorganic light-emitting devices of different colors arranged in a matrix form. Each pixel has a circuit that controls the driving time and current provided to the light-emitting devices based on image data voltage.
- The display panel has a pixel array with inorganic light-emitting devices of different colors arranged in a matrix form.
- Each pixel has a circuit that controls the driving time and current provided to the light-emitting devices based on image data voltage.
- A sensor is included to sense the current flowing through a driving transistor in the pixel circuit and outputs sensing data.
- A corrector is used to adjust the image data voltage applied to the pixel circuit based on the sensed data.
Potential Applications
- This display device can be used in various electronic devices such as televisions, computer monitors, smartphones, and tablets.
- It can be applied in advertising displays, digital signage, and public information displays.
Problems Solved
- The device solves the problem of inaccurate image display by correcting the image data voltage based on the sensed data.
- It addresses the issue of inconsistent driving time and current provided to the inorganic light-emitting devices, ensuring accurate and consistent color representation.
Benefits
- The display device provides improved image quality and color accuracy.
- It allows for precise control of driving time and current, resulting in better overall performance.
- The correction based on sensed data ensures consistent and reliable image display.
Original Abstract Submitted
A display device includes: a display panel including a pixel array, in which pixels that include a plurality of inorganic light-emitting devices of different colors are arranged in a matrix form, and a pixel circuit that is provided for each of the plurality of inorganic light-emitting devices, and the pixel circuit controls, on the basis of an applied image data voltage, the driving time and the magnitude of driving current provided to the inorganic light-emitting devices; a sensor which senses, on the basis of a voltage applied to the pixel circuit, a current flowing through a driving transistor included in the pixel circuit and which outputs sensing data corresponding to the sensed current; and a corrector which corrects, on the basis of the sensed data, the image data voltage applied to the pixel circuit.
