Display Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240257736 titled 'Display Device
The display apparatus described in the patent application includes a pixel row with multiple pixels, each containing a driving transistor that supplies current to a light-emitting element. The pixels also have gate electrodes, first electrodes, and second electrodes.
- The first transistor in each pixel receives a first scan signal through its gate electrode, a data voltage through its first electrode, and has a second electrode.
- The second transistor in each pixel receives a second scan signal through its gate electrode, an initialization voltage through its first electrode, and has a second electrode.
- A ripple detection unit identifies ripples in pixel rows.
- A compensation image data calculation unit determines the compensation image data magnitude based on the difference between the initialization voltage level of a pixel row with ripples and a reference initialization voltage level.
- Key Features and Innovation:**
- Implementation of driving transistors in pixels for providing current to light-emitting elements.
- Utilization of gate electrodes, first electrodes, and second electrodes in each pixel.
- Detection of ripples in pixel rows by a dedicated unit.
- Calculation of compensation image data based on voltage level differences in pixel rows.
- Potential Applications:**
This technology can be used in various display devices such as televisions, monitors, and smartphones to improve image quality and reduce visual artifacts.

Original Abstract Submitted
a display apparatus includes a pixel row including a plurality of pixels. each pixel includes a driving transistor that provides a driving current to a light emitting element, and includes a gate electrode, a first electrode, and a second electrode. the first transistor includes a gate electrode that receives a first scan signal, a first electrode receives a data voltage, and a second electrode. the second transistor includes a gate electrode that receives a second scan signal, a first electrode that receives an initialization voltage, and a second electrode. a ripple detection unit detects ripples that occur in pixel rows in the display apparatus. a compensation image data calculation unit calculates the magnitude of the compensation image data based on the difference between the voltage level of the initialization voltage of a pixel row in which the ripple occurs and a reference initialization voltage level.
