A method and electronic device for increasing brightness

Abstract

A method and electronic device for increasing brightness. The present invention provides an electronic device, which includes: a first light emitting module, a second light emitting module, a main driving unit and a first auxiliary driving unit; the driving unit includes a first control terminal and a second control terminal, the The first control terminal is used to supply power to the first light-emitting module during the first period and stop supplying power to the first light-emitting module during the second period, and the second control terminal is used to light the second light-emitting module only during the second period The second light-emitting module stops supplying power to the second light-emitting module during the first period, so that the first light-emitting module emits first light during the first period and the second light-emitting module emits light during the second period. The second light: the first auxiliary driving unit is used to supply power to the first light-emitting module during the second period, so that the first light-emitting module emits fourth light during the second period.

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
