GAMMA VOLTAGE GENERATION CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18232573 titled 'GAMMA VOLTAGE GENERATION CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
- The patent application describes a display device that includes a display unit, a gamma voltage generator, and a data driver. - The display unit has a pixel that displays images based on a first power voltage and a data signal. - The gamma voltage generator generates gamma voltages for the data driver. - The data driver uses the gamma voltages to generate the data signal for the pixel. - The gamma voltage generator generates first and second reference voltages. - It corrects the first and second reference voltages using a target voltage and an external power voltage provided by the display unit. - The gamma voltage generator divides the corrected reference voltages to generate the gamma voltages. - The target voltage is set based on the first reference voltage, the second reference voltage, or a ground voltage.
Original Abstract Submitted
A display device includes a display unit including a pixel which displays an image based on a first power voltage and a data signal, a gamma voltage generator which generates gamma voltages, and a data driver which generates the signal using the gamma voltages and provides the data signal to the pixel. The gamma voltage generator generates first and second reference voltages, generates first and second corrected reference voltages by correcting the first and second reference voltages using a target voltage and an external power voltage provided from the display unit in correspondence with the first power voltage, and generates the gamma voltages by dividing the first and second corrected reference voltages. The gamma voltage generator sets the target voltage based on at least one selected from the first reference voltage, the second reference voltage, and a ground voltage.
