Abstract

The invention provides a display device comprising a substrate, a first light emitting element and a second light emitting element. The substrate comprises at least one pixel area. The first light emitting element is arranged in the pixel area, and is used for emitting first coloured light, and has a first light emitting efficiency-injection current density function. The second light emitting element is arranged in the pixel area, and is used for emitting second coloured light, and has a second light emitting efficiency-injection current density function. The junction of the second light emitting efficiency-injection current density function and the first light emitting efficiency-injection current density function is used for defining a critical conversion current density, and the first coloured light and the second coloured light belong to the same colour system. By providing the display device, the power consumption of the display device can be effectively reduced, and the aim of high efficiency and energy conservation is achieved.

Description

technical field [0001] The present disclosure relates to a display device and a control method thereof, in particular to a high-efficiency display device and a control method thereof. Background technique [0002] With the increase of information processing capacity of portable electronic devices, such as notebook computers, tablet computers, smart watches, mobile phones, etc., the standby time will be further shortened, and the battery life often cannot meet consumers' expectations. The display is one of the most power-consuming components in the portable device. If the power consumption of each pixel structure in the display can be effectively reduced, the standby time of the portable device can be improved and the problem of insufficient battery life can be solved. [0003] Therefore, there is a need to provide a display device with low power consumption, high stability and good luminous efficiency and a control method thereof to solve the problems faced by the prior art....
