PIXEL AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18053485 titled 'PIXEL AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a pixel structure for a display device that includes multiple transistors and a storage capacitor. The pixel structure allows for time division of the voltage provided through a data line to control the light emitting element.
- The pixel structure includes a light emitting element, multiple transistors, and a storage capacitor.
- The transistors are connected in a specific configuration to control the voltage provided to the light emitting element.
- The voltage provided through the data line is divided into a data voltage and an on-bias voltage.
- The data voltage is provided to the gate electrode of the first transistor when both the second and third transistors are turned on.
- The on-bias voltage is provided to the first electrode of the first transistor when the second transistor is turned on and the third transistor is turned off.
Potential Applications
- Display devices such as televisions, computer monitors, and mobile phone screens.
- Virtual reality and augmented reality headsets.
- Automotive displays and infotainment systems.
Problems Solved
- Efficient control of the voltage provided to the light emitting element in a pixel structure.
- Time division of the voltage to achieve accurate and precise control.
- Reduction of power consumption and improved display quality.
Benefits
- Improved image quality and color accuracy in display devices.
- Reduced power consumption, leading to longer battery life in portable devices.
- Enhanced control and flexibility in displaying images and videos.
Original Abstract Submitted
A pixel includes a light emitting element, a first transistor connected to the light emitting element, a second transistor connected between a data line and a first electrode of the first transistor, a third transistor connected between a gate electrode of the first transistor T and a second electrode of the first transistor, a fourth transistor connected between a gate electrode of the first transistor and an initialization power source, and a storage capacitor connected between the first power source and the gate electrode of the first transistor. A voltage provided through the data line is time divided into a data voltage provided to the gate electrode of the first transistor when both the second and third transistors turn on, and an on-bias voltage provided to the first electrode of the first transistor when the second transistor turns on and the third transistor turns off.
