This application claims the priority benefit of China application serial no. 201910602151.7, filed on Jul. 5, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The present disclosure relates to an optical device and a control method, and in particular, to a display device and a display control method.
Generally speaking, a known flat-panel display, for example, a liquid crystal display (LCD), mainly includes components such as an LCD panel and a backlight module, the LCD panel does not emit light, and for enabling the flat-panel display to clearly display an image, the backlight module is required to provide illumination. A known backlight module includes components such as a light source, a light guide plate and an optical thin film, and the backlight module mostly adopts a light emitting diode (LED) capable of emitting a visible light band.
However, the LED capable of emitting a visible light band requires certain driving power. Therefore, under the condition that a known backlight module is adopted, if a display mode for a standby state is added to meet a business requirement, certain energy sources and power still require to be consumed, which may increase the operating cost of a product and affect the energy efficiency of the product and does not meet market requirements.
