  • Patent number: 7663524
    Abstract: A multi-channel display driver circuit incorporating modified D/A converters has a plurality of digital comparators connected to a number generator. Each digital comparator has an output, a digital data input and a reference input. The reference inputs of all digital comparators are connected to the number generator and the outputs are respectively connected to corresponding data channels of a display. By the proposed technique, each digital comparator obtains a unique non-sequence reference signal, and then compares it with the input digital data signal. Since the non-sequential signals are input to the reference input of the digital comparator, the overshoot distortion, the harmonic distortion and the electromagnetic interference problems are prevented. Therefore, the precise imaging can be obtained with this signal modulation technique in small circuit size.

  • Patent number: 7616222
    Abstract: A control module for reducing power dissipation is connected to a column driving unit and a row driving unit. The control module includes a memory for storing display data temporarily and an arithmetic/logic unit connected to the memory. The arithmetic/logic unit takes grayscale image data of a current conducted row as a base row to compare with the grayscale image data of n rows that are temporarily stored in the memory and waiting to be scanned, so as to select the row with a minimum gray level difference as a next conducted row.

  • Patent number: 7375734
    Abstract: A GAMMA adjustment method for a multi-channel driver of a monitor and device thereof are provided. The GAMMA adjustment method converts an m-bit input signal of a high bit signal corresponding to an m-bit simulated GAMMA curve into an n-bit signal of a low bit signal. Then the n-bit signal together with an n-bit input signal are input to a driver component. The driver component compares the two low-bit signals to generate a PWM driver signal supplied to a data channel of the monitor. Since the two n-bit signals of the driver component are of low quantity bit, the driver chooses n-bit digital driver components to greatly reduce an overall layout area of the driver and further to reduce manufacture cost.
