Patent ID: 6977647

Claim:
A flat panel display, comprising: a power unit generating a constant voltage; a gate voltage generating unit generating a gate on/off voltage; a controller comprising: a signal processing unit receiving driving data and a driving control signal and generating RGB data, a scan control signal and a column control signal; a gamma data generating unit generating digital gamma data with reference to the constant voltage from the power unit, the digital gamma data having a plurality of gradation values; and a mixer unit mixing the digital gamma data and the RGB data to form a mixed signal, the digital gamma data arranged in a blanking section of the RGB data; a scan driver unit receiving the scan control signal and the gate on/off voltage and generating a scan signal; a column driver unit converting the digital gamma data into an analog gradation voltage and generating a column signal based on the column control signal, the RGB data and the analog gradation voltage; and a flat display panel displaying an image based on the scan signal and the column signal.
