Abstract
A drive circuit and a display device are provided. The drive circuit comprises a programmable gamma IC, a timing controller, a memory, and a control interface. A display device is also provided. After starting up the drive circuit and the display device provided, the gamma value of the programmable gamma IC can be updated in real-time to make the output voltage controlled thereby as accurate as possible. Accordingly, the assembled display device can show the original object or source image more truly.
