1. Technical Field
The present disclosure relates to a display device and an electronic apparatus.
2. Description of the Related Art
A liquid crystal display panel, a self-luminous type display panel that emits light from a self-luminous body such as an organic light-emitting diode (OLED), and the like include a plurality of pixels each including a first sub-pixel that displays red, a second sub-pixel that displays green, and a third sub-pixel that displays blue, for example. A technique has been developed for improving brightness of the pixel by adding a fourth sub-pixel that displays white to the pixel.
Even when colors are displayed based on output signals having the same gradation, the brightness of the displayed colors may be different due to a difference in element characteristics. For example, the brightness of the third sub-pixel that displays blue may be smaller than that of the other sub-pixels. Accordingly, in this case, to keep color balance, the brightness of the first sub-pixel and the second sub-pixel may be limited to correspond to the maximum brightness of the third sub-pixel by providing a light shielding layer or adjusting an output in a circuit.
When the maximum brightness is limited, the brightness may be expanded only up to brightness lower than the brightness that can be actually expressed, so that an image having high brightness cannot possibly be displayed appropriately.
To solve the above problem, the present invention provides an electronic apparatus and a display device that each appropriately display an image having high brightness.
