Abstract | A digital video signal processing device for LCDs. A display memory stores digital video signals. A scaler controller set on a first circuit board adjusts the image size of the digital video signal and outputs a first display data. The LCD includes a plurality of display cells respectively coupled to the corresponding data electrode and gate electrode. The LCD displays the image data according to a second display data. An LCD driver includes a data driver for driving the data electrodes and a gate driver for driving the gate electrodes. A timing controller set on a second circuit board connected to the first circuit board, controls the LCD driver. A gamma adjusting circuit only set on one of the first circuit board, the second circuit board and the LCD driver, adjusts the brightness of the first display data and generates the second display data. |
