DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17983462 titled 'DISPLAY DEVICE
Simplified Explanation
The abstract describes a display device that includes a display panel, a display panel driver, a memory device, and a panel temperature determiner.
- The display panel consists of multiple pixels.
- The display panel driver is responsible for driving the display panel.
- The memory device stores a reference current-temperature model, a global offset, and a local offset.
- The reference current-temperature model is set for the display panel during manufacturing.
- The global offset is calculated based on the reference current-temperature model in the manufacturing stage.
- The local offset is calculated based on the characteristic difference between the pixels in the manufacturing stage.
- The panel temperature determiner measures sensing currents flowing through the pixels when a temperature sensing voltage is applied.
- Correction sensing currents are calculated by applying the global offset and the local offset to the sensing currents.
- The temperatures of the pixels are determined by substituting the correction sensing currents into the reference current-temperature model.
Potential Applications
- Display devices such as televisions, computer monitors, and mobile device screens.
- Any application that requires accurate temperature measurement of pixels in a display panel.
Problems Solved
- Inaccurate temperature measurement of pixels in a display panel.
- Variations in pixel characteristics during manufacturing.
Benefits
- Improved accuracy in temperature measurement of pixels.
- Enhanced performance and efficiency of display devices.
- Better quality control during manufacturing.
Original Abstract Submitted
A display device including: a display panel including a plurality of pixels; a display panel driver configured to drive the display panel; a memory device configured to store a reference current-temperature model that is set for the display panel, a global offset of the display panel, which is calculated based on the reference current-temperature model in a manufacturing stage of the display panel, and a local offset of the display panel, which is calculated based on a characteristic difference between the pixels in the manufacturing stage; and a panel temperature determiner configured to measure sensing currents flowing through the pixels when a temperature sensing voltage is applied to the pixels, calculate correction sensing currents by applying the global offset and the local offset to the sensing currents, and determine temperatures of the pixels by substituting the correction sensing currents into the reference current-temperature model.
