METHOD AND DEVICE FOR CONTROLLING DISPLAY OF DISPLAY DEVICE
First Claim
1. A display control method of controlling a display of a display device, wherein the display device includes a red sub pixel, a green sub pixel, a first blue sub pixel, and a second blue sub pixel emitting light having a different central wavelength from that of the first blue sub pixel, the method comprising:
- setting a display mode of the display device to emit blue light as one of a first mode in which the first blue sub pixel is used, a second mode in which the second blue sub pixel is used, and a third mode in which both the first blue sub pixel and the second blue sub pixel are used; and
sub pixel rendering red input data, green input data, and blue input data according to an arrangement of the red sub pixel, the green sub pixel, the first blue sub pixel, and the second blue sub pixel and converting the red input data, the green input data, and the blue input data into output data,wherein converting includes performing sub pixel rendering by changing a size and a coefficient of a rendering filter with respect to each of the red input data, green input data, and blue input data according to the display mode.

Abstract
A display control method and device for controlling a display device. The display device includes a red sub pixel, a green sub pixel, a first blue sub pixel, and a second blue sub pixel emitting light having a different central wavelength from that of the first blue sub pixel. The display control includes setting a display mode of the display device as one of a first mode in which the first blue sub pixel is used to emit blue light, a second mode in which the second blue sub pixel is used, and a third mode in which both the first blue sub pixel and the second blue sub pixel are used; and sub pixel rendering data according to an arrangement of the red sub pixel, the green sub pixel, the first blue sub pixel, and the second blue sub pixel and converting rendered data into output data.
