==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.

Benefits of this technology:

* Improved image quality: The gamma voltage generator helps achieve better image quality by accurately controlling the voltage levels and applying gamma correction.
* Enhanced visual experience: By fine-tuning the gamma correction, the technology enhances the visual experience for users, providing more vibrant and realistic images on display devices.


==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.
