VARIABLE TAP GAMMA AMPLIFIER, GAMMA VOLTAGE GENERATOR, AND DISPLAY DRIVING INTEGRATED CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18310334 titled 'VARIABLE TAP GAMMA AMPLIFIER, GAMMA VOLTAGE GENERATOR, AND DISPLAY DRIVING INTEGRATED CIRCUIT
Simplified Explanation
The abstract describes a patent application for a gamma voltage generator. Here is a simplified explanation of the abstract:
- The gamma voltage generator includes a first resistor string connected between a 0-th terminal and a first terminal, which outputs first gamma voltages.
- A 0-th gamma amplifier outputs a 0-th tap voltage to the 0-th terminal using a 0-th reference voltage.
- A first variable tap gamma amplifier outputs a first tap voltage to the first terminal using a first reference voltage.
- A gamma control logic circuit selectively activates a first tap change signal based on a first grayscale ratio of first line data.
- The first variable tap gamma amplifier outputs a second tap voltage to a first central terminal of the first resistor string using a second reference voltage, in response to the activated first tap change signal.
Potential applications of this technology:
- Display devices: The gamma voltage generator can be used in various display devices such as LCD screens, OLED screens, and LED screens to control the voltage levels and improve the image quality.
- Image processing: The gamma voltage generator can be utilized in image processing systems to adjust the gamma correction and enhance the visual appearance of images.
Problems solved by this technology:
- Voltage control: The gamma voltage generator solves the problem of accurately controlling the voltage levels in display devices, ensuring optimal image quality.
- Gamma correction: By providing variable tap voltages, the gamma voltage generator addresses the need for precise gamma correction, resulting in improved color accuracy and contrast in displayed images.

Original Abstract Submitted
Among the implementations described herein is a gamma voltage generator which includes a first resistor string that is connected between a 0-th terminal and a first terminal and outputs first gamma voltages, a 0-th gamma amplifier that outputs a 0-th tap voltage to the 0-th terminal by using a 0-th reference voltage, a first variable tap gamma amplifier that outputs a first tap voltage to the first terminal by using a first reference voltage, and a gamma control logic circuit that selectively activates a first tap change signal based on a first grayscale ratio of first line data. The first variable tap gamma amplifier outputs a second tap voltage to a first central terminal of the first resistor string by using a second reference voltage, in response to the first tap change signal thus activated.
