DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240184399 titled 'DISPLAY DEVICE
Simplified Explanation
The display device described in the abstract includes a display portion for showing images and a sense portion that detects external inputs. The sense portion consists of first sense electrodes, second sense electrodes, and compensation electrodes, which work together to sense and respond to external inputs.
- The display device has a display portion that shows images.
- The sense portion of the device detects external inputs.
- The sense portion includes first sense electrodes that receive signals in response to external inputs.
- Second sense electrodes are positioned at a distance from the first sense electrodes.
- Compensation electrodes are placed between the first sense electrodes and receive a compensation signal that is phase-inverted with the first sense signal.
- Potential Applications:**
This technology could be used in touchscreens, interactive displays, and other devices that require precise sensing of external inputs.
- Problems Solved:**
This technology solves the problem of accurately detecting and responding to external inputs on a display device.
- Benefits:**
The benefits of this technology include improved accuracy in sensing external inputs, leading to a better user experience and increased functionality of the display device.
- Potential Commercial Applications:**
Potential commercial applications of this technology include smartphones, tablets, interactive kiosks, and other touch-sensitive devices.
- Possible Prior Art:**
One possible prior art for this technology could be capacitive touchscreens that use electrodes to detect touch inputs.
- Unanswered Questions:**
- How does the phase inversion of the compensation signal and first sense signal improve sensing accuracy?**
The phase inversion helps to cancel out noise and interference, resulting in a more accurate detection of external inputs.
- What materials are commonly used for the electrodes in display devices with sensing capabilities?**
Materials such as indium tin oxide (ITO) are commonly used for electrodes in display devices due to their transparency and conductivity.
Original Abstract Submitted
a display device according to an example embodiment includes a display portion displaying an image, and a sense portion that is disposed over one side of the display portion, and senses an external input, wherein the sense portion includes: at least one of first sense electrodes receiving a first sense signal that is changed in response to the external input, at least one of second sense electrodes that are disposed at a distance from the first sense electrodes, wherein the first sense electrodes are disposed between the second sense electrodes, and at least one of compensation electrode that are disposed spaced apart from and between the first sense electrodes, and to which a compensation signal is applied, wherein the compensation signal and the first sense signal are inverted in phase.
