A display device includes a display panel, a power supply, and a driving circuit. The display panel includes a plurality of pixels. The power supply is configured to supply a first power voltage and a second power voltage to the display panel. The driving circuit is configured to determine, based on a viewing angle information signal, whether to operate the display device in a general mode or a low power mode. If the display device is operated in the low power mode, the driving circuit is further configured to deactivate the power supply, and supply a first subsidiary power voltage and a second subsidiary power voltage to the display panel.

Technical Field
The present disclosure generally relates to a display device, and more particularly, to a display device having reduced power consumption.
FIG. 1 is a block diagram of a display device according to an embodiment.
FIG. 2 illustrates a main viewing angle range of a display device according to an embodiment.
FIG. 3 is a graph of pixel brightness relative to a user's viewing angle during operation of a display device according to an embodiment.
Exemplary embodiments are next described in detail with reference to the accompanying drawings. It is noted that the inventive concept may be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so as to convey the scope of the inventive concept to those skilled in the art.
In the drawings, lengths and sizes of regions may be exaggerated for clarity. Like reference numerals in the drawings denote like elements throughout.
Terms such as ‘first’ and ‘second’ may be used to describe various components, but should not be construed in a limiting manner. Rather, those terms are merely used to distinguish one component from another. For example, a first component may be interchangeably referred to as a second component, and a second component may be interchangeably referred to as a first component, and so forth, without departing from the spirit and scope of the present disclosure. Furthermore, the use of ‘and/or’ may include any one of or a combination of the components mentioned.
