摘要： There is provided a bit refresh circuit and method of checking errors in bit values of a register and refreshing the bit values, and an integrated circuit comprising the bit refresh circuit. The integrated circuit includes a refresh unit checking whether or not the bit values of the register storing data used to control the operations of a logic circuit changes due to external noise. The refresh unit checks bit-by-bit whether or not there are errors in the bit values due to the external noise. If there are errors in the bit values of the register, the data of the associated bit values stored in a memory are refreshed into the register.

摘要： Provided is a display panel driving circuit. The display panel driving circuit rearranges and stores image data input of a predetermined number of source lines externally so that data of the same channel neighbor each other, and compares the rearranged data. If the rearranged data are identical, only one buffer is driven, and common data is transferred to a plurality of source lines, outputs the rearranged data according to each channel, sequentially outputs data according to each source line using source drivers of each channel. Thus, when output data neighboring source lines are identical, the current required for the buffer is reduced.

摘要： A display driver circuit configured to be shared by three grey-scale voltage generators to be respectively used with red (R), green (G) and blue (B) colors. In particular, two of the three grey-scale voltage generators share first and second resistor strings, gamma voltage selectors, and gamma adjustment buffers provided in the other grey-scale voltage generator, thereby reducing the size and power consumption of the display driver circuit. Also, when only a single grey-scale voltage is output, it is possible to deactivate the grey-scale voltages provided by two of the grey-scale generators and further reduce power consumption.
