PIXEL, DISPLAY DEVICE, CONTROLLER AND METHOD OF DRIVING DISPLAY DEVICE INCLUDING BIAS POWER LINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240105104 titled 'PIXEL, DISPLAY DEVICE, CONTROLLER AND METHOD OF DRIVING DISPLAY DEVICE INCLUDING BIAS POWER LINE

Simplified Explanation

The abstract describes a patent application related to a pixel structure that includes a light emitting element and transistors for controlling the operation of the light emitting element. The bias control transistor is responsible for switching the electrical connection between the power line and the bias power line to transmit a bias voltage that increases in voltage level in one frame period.

• Light emitting element
• First transistor with gate electrode
• Bias control transistor for switching electrical connection
• Increase in bias voltage level in one frame period

Potential Applications

The technology described in the patent application could be applied in the development of high-resolution displays, such as OLED screens, where precise control of individual pixels is essential.

Problems Solved

This technology solves the problem of efficiently controlling the brightness and color accuracy of individual pixels in a display, leading to improved image quality and energy efficiency.

Benefits

The benefits of this technology include enhanced display performance, lower power consumption, and potentially longer lifespan of the display due to optimized control of the light emitting elements.

Potential Commercial Applications

• High-resolution OLED displays for smartphones, TVs, and other electronic devices

Possible Prior Art

One possible prior art could be the development of similar pixel structures in display technologies, such as LCD or OLED screens, where transistors are used to control the operation of individual pixels.

How does this technology compare to existing pixel structures in terms of energy efficiency?

The patent application does not provide specific details on the energy efficiency of the proposed pixel structure compared to existing technologies. Further research or testing would be needed to determine the energy-saving potential of this innovation.

What impact could the increasing bias voltage level have on the overall performance and longevity of the display?

The abstract mentions a sequential increase in the bias voltage level in one frame period. It is unclear how this voltage increase could affect the overall performance and lifespan of the display over time. Further analysis or experimentation would be required to assess any potential implications of this aspect of the technology.
