Embodiment Construction

[0034] In order to solve the various shortcomings of the above-mentioned general color-sequential display after long-term use, the present invention discloses a color-sequential display and a method for adjusting the luminance of the related backlight module to reduce the aging phenomenon caused by the above-mentioned light-emitting diodes. The method for adjusting the luminance of the color sequential display and the related backlight module disclosed in the present invention not only considers the temperature of the color sequential display as one of the considerations for adjusting the brightness of light-emitting diodes of different primary colors, but also uses the configuration of the color sequential display The backlight module is affected by its surrounding brightness (that is, ambient light) as one of the considerations, so that the backlight module can eliminate the brightness deviation caused by ambient light in advance when determining its luminous brightness, and a...

Abstract

The invention relates to a method for adjusting the luminosity of a display and a related backlight module. The standard luminosity is found according to the detected temperature and actual luminosity of the backlight module and a target luminosity value used by the display. In addition, when the actual luminosity is adjusted, the influence caused by ambient light is also considered, so that the adjusted actual luminosity is not interfered by the ambient light. The method solves the problem of the luminance of the common color sequence type display is insufficient when the luminance of the light-emitting diode of the backlight module is non-linearly changed and the light-emitting diode is aged caused by the factors such as the increment of service time, the change of the temperature and the like.

Description

technical field [0001] The invention relates to a method for adjusting the luminous brightness of a display and a related backlight module. Background technique [0002] Traditional liquid crystal displays mainly use color filters (ColorFilter) as a medium to filter out different primary colors to achieve the purpose of full-color (FullColor) display. However, due to the need to filter out light during this process, the resulting Most of the luminous brightness will be filtered out by the color filter, resulting in low luminous efficiency. Therefore, a display using a color-sequential method (referred to as a color-sequential display) is used to replace a display using color filters to maintain a higher luminous efficiency. Since the color sequential display emits light corresponding to different primary colors according to a predetermined color sequence in a short period of time, the human visual persistence phenomenon can be used to achieve the purpose of mixing colors an...
