Abstract
A Gamma voltage divider circuit, a voltage adjusting method, and a liquid crystal display device are proposed. Compared to the arrangement of voltage dividing resistor string of the existing Gamma voltage divider circuit, by changing the mapping of band point voltages, the application can optimize accuracy of low gray-level voltages in a further step, improve the display effect, and at the same time, reduce the number of voltage dividing resistors and lower the complexity and cost of the Gamma voltage divider circuit. The Gamma voltage divider circuit is adaptable to the voltage dividing resistor string settings of OLED display panels as well as LCD panels.
