Method for increasing brightness and electronic device

Abstract

The invention provides a method for increasing brightness and an electronic device, and provides an electronic device. The electronic device comprises a first light-emitting module, a second light-emitting module, a main drive unit and a first auxiliary drive unit, wherein the drive unit comprises a first control end and a second control end; the first control end is used for supplying electricity to the first light-emitting module at a first time frame and stopping supplying electricity to the first light-emitting module at a second time frame; the second control end is used for lightening the second light-emitting module only at the second time frame and stopping supplying electricity to the second light-emitting module at the first time frame, so that the first light-emitting module sends out a first ray at the first time frame and the second light-emitting module sends out a second ray at the second time frame; and the first auxiliary drive unit is used for supplying electricity to the first light-emitting module at the second time frame, so that the first light-emitting module sends out a fourth ray at the second time frame.

Description

technical field [0001] The invention relates to an electronic device capable of emitting light, in particular to an electronic device capable of increasing brightness. Background technique [0002] Electronic devices need to provide multiple light sources to light up images, such electronic devices may be projectors or screens with backlights. These electronic devices usually require a control unit to control the light of different light sources to achieve the purpose of color mixing, such as figure 1 As shown, the electronic device 100 includes a main driving unit 120, switches SW1, SW2, SW3 and light emitting modules 110A, 110B and 110C, and the main driving unit 120 has a control terminal 120C A , 120C B with 120C C They are used to respectively control the switches SW1 , SW2 and SW3 to further control the power supply status of the light emitting modules 110A, 110B and 110C. The main driving unit 120 requires high energy consumption when driving the light-emitting mo...

AI Technical Summary

Problems solved by technology

[0003] The main driving unit 120 can turn on / off the light emitting modules 110A, 110B, and 110C in sequence according to the types of colors to be mixed. The required colors can be mixed by different turn-on times of each light emitting module. When making images, different parameters need to be considered. For example, when the electronic device is in a high-brightness environment or the brightness requirements of the displayed image are high, the brightness consideration is an important adjustment value, and in figure 1 Under the framework, only one light-emitting module can be turned on at the same time point, which cannot meet the demand for brightness under certain conditions
