Abstract: A display apparatus includes a gate driving control circuit, a gate driver and a display panel. The gate driving control circuit generates N gate clock signals and N inversion gate clock signals based on N gate clock control signals, phases of which partially overlap with each other. Each inversion gate clock signals has an opposite phase to a respective gate clock signal. The gate driver generates gate signals based on the N gate clock signals or the N inversion gate clock signals and applies the gate signals to gate lines. The display panel includes pixels, each connected to a respective gate line and a respective data line. Each of the pixels has a longer side in parallel with gate lines and a shorter side in parallel with the data lines. A number of the gate clock control signals is an integer multiple of a number of colors of the pixels.

Abstract: A method of driving a light source includes outputting a variable driving voltage to a light source part, sensing a first voltage based on the driving voltage and developed at a first end of the light source part, sensing a second voltage developed at a second end of the light source part due to current passing through the light source part and adjusting the driving voltage while using the first and second voltages so that power consumption by the light source part is substantially constant irrespective of temperature of the light source part and/or irrespective of a duty cycle ration being used to drive the light source part. Thus, a luminance of the light source part may be maintained at substantially uniform levels.
