Abstract

Provided are a Gamma reference voltage generating device and a display. The Gamma reference voltage generating device comprises a Gamma reference voltage source and a Gamma reference voltage converting module, the Gamma reference voltage source being connected to the Gamma reference voltage converting module and configured to provide Gamma reference voltages, wherein the Gamma reference voltage generating device further comprises at least one temperature compensation circuit which is connected to the Gamma reference voltage converting module and configured to automatically adjust output voltages according to temperature change to compensate the Gamma reference voltages output by the Gamma reference voltage source through the Gamma reference voltage converting module. The display comprises the above Gamma reference voltage generating device, and thus can avoid poor display due to temperature influences.
