Devices with Displays Having Transparent Openings and Uniformity Correction - A simplified explanation of the abstract
This abstract first appeared for US patent application 18481119 titled 'Devices with Displays Having Transparent Openings and Uniformity Correction
Simplified Explanation
The patent application describes an electronic device with a display and an optical sensor underneath it. Transparent windows are placed over the sensor, which can reduce the resolution of the display in those areas. To avoid a visible border between the reduced resolution and full resolution areas, the device uses uniformity compensation circuitry.
- The uniformity compensation circuitry compensates pixel data to maintain a consistent appearance across the display.
- It uses compensation maps with factors associated with pixel locations to adjust the pixel data.
- Region-specific gamma look-up tables are used to apply different gamma curves to pixels in different regions of the display.
- The circuitry can also create a transition region between different regions of the display.
Potential applications of this technology:
- Mobile devices with displays that have optical sensors underneath, such as smartphones or tablets.
- Any electronic device that requires a display with transparent windows over an optical sensor, such as cameras or touchscreens.
Problems solved by this technology:
- Prevents visible borders between different resolution areas of the display, ensuring a seamless visual experience.
- Compensates for the reduced resolution caused by the presence of transparent windows over the optical sensor.
Benefits of this technology:
- Maintains a consistent appearance across the display, even with the presence of transparent windows.
- Enhances the visual quality of the display by compensating for reduced resolution areas.
- Allows for the use of different gamma curves in different regions of the display, improving image quality and color accuracy.
Original Abstract Submitted
An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To prevent a visible border between the reduced resolution areas of the display and full resolution areas of the display, uniformity compensation circuitry may be used to compensate pixel data. The uniformity compensation circuitry may output compensated pixel data for the display using one or more compensation maps that include compensation factors associated with pixel locations. The uniformity compensation circuitry may also use region-specific gamma look-up tables to apply different gamma curves to pixels in different regions of the display. The uniformity compensation circuitry may also be used to form a transition region between different regions of the display.
