Abstract
A display apparatus includes an RGB-RGBX signal converter having a variable RGB-RGBX conversion ratio and configured to convert an RGB signal into an RGBX signal. An RGBX type self light-emitting display is configured to display video, based on the RGBX signal obtained by the RGB-RGBX signal converter. A controller is configured to control the RGB-RGBX conversion ratio utilized for converting the RGB signal into the RGBX signal, in accordance with a display position of the RGB signal.

A display apparatus comprising:
- an RGB-RGBX signal converter having a variable RGB-RGBX conversion ratio and configured to convert an RGB signal into an RGBX signal, X refers to an arbitrary color other than R, G, and B;
- an RGBX type self light-emitting display configured to display video, based on the RGBX signal obtained by the RGB-RGBX signal converter, and
- a controller configured to control the RGB-RGBX conversion ratio utilized for converting the RGB signal into the RGBX signal, in accordance with a display position of the RGB signal.
A display apparatus comprising:
- an RGB-RGBX signal converter having a variable RGB-RGBX conversion ratio, and configured to convert a RGB signal into a RGBX signal, X refers to an arbitrary color other than R, G, and B;
- an RGBX type self light-emitting display configured to display video, based on the RGBX signal obtained by the RGB-RGBX signal converter, including:
- a video display region which is an area between upper and lower parts of the self light-emitting display, and configured to display an input video;
- a no-video display regions which are areas of the upper and lower parts of the self light-emitting display, and configured to display gray bands when an aspect ratio of the input video is different from an aspect ratio of the self light-emitting display,
- a determination circuit configured to determine whether a display position of the RGB signal is in the video display region or in the no-video display regions;
- and
- a controller configured to control the RGB-RGBX conversion ratio utilized for converting the RGB signal into the RGBX signal, in accordance with a determination result of the determination circuit,
- wherein the controller sets a different value to the RGB-RGBX conversion ratios of a case where the display position is in the video display region and a case where the display position is in the no-video display regions.
