Abstract:
A display driving circuit comprising a video signal transformation circuit, a reference voltage generating circuit, a DAC and an interpolation operational amplifier is provided. The video signal transformation circuit transforms an input video signal into a transformed video signal with a higher bit depth. The transformed video signal comprises an upper n bits data and a lower m bits data, wherein n+m equals a bit depth of the transformed video signal. The reference voltage generating circuit generates reference voltages. The DAC selects a first reference voltage and a second reference voltage to interpolation operational amplifier from the reference voltages according to an upper n bits data of the transformed video signal. The interpolation operational amplifier outputs a driving voltage to display device according to the first reference voltage, the second reference voltage and the lower m bits data of the transformed video signal.

Claim (Index 1):
A display driving circuit, comprising:\n a video signal transformation circuit for transforming an input video signal into a transformed video signal having a bit depth higher than that of the input video signal according to one or more look-up tables wherein a bit depth of the input video signal is a first number, the bit depth of the transformed video signal is a second number; a digital to analog converter (DAC) coupled to the video signal transformation circuit, configured to select a first reference voltage and a second reference voltage from a plurality of reference voltages according to at least a third number of bits of data of the transformed video signal, wherein the third number is less than the second number and the number of the reference voltages is less than 2 m, where m denotes the first number; and an operational amplifier coupled to the digital to analog converter and configured to perform interpolation on the first and second reference voltages so as to generate a driving voltage corresponding to the second number of bits of the transformed video signal.
