Abstract
An exemplary gamma voltage output circuit () has an internal resistor string (), which has a plurality of resistors and a plurality of nodes; at least one external resistor string (), which has a plurality of resistors and a plurality of nodes; a plurality of switching circuit (), each switching circuit having at least one input end () and at least one output end (). The internal and the at least one external resistor strings connect in series between the power source AVDD and ground, respectively. Each node outputs a gamma voltage. The nodes of internal and the at least one external resistor strings respectively are connected to the output end and the input end, the resistors of the internal resistor string parallel connecting to corresponding resistors of the at least one external resistor string through the corresponding switching circuit.
