Abstract

The embodiment of present invention provides a backlight assembly, mobile terminal and control method, the backlight assembly includes a back light source, which includes a first light cell with blue ray and a second light cell with preset color ray, wherein the preset color ray is a color ray excluding the blue ray; and a first control module connected with the first light cell, which is applied to regulate the electrical current value of the first light cell; or a second control module connected with the first light cell and the second light cell, which is applied to regulate the total value of the electrical current of the first light cell and the second light cell. By separating the first light cell with blue ray from the second light cell with other preset color ray, the value of the electrical current of the first cell is adjusted to control the light intensity of the blue ray in the backlight source, under the precondition that the penetration rate of the display panel board and the light spectrum of the backlight source are not altered, the adjustment of the blue ray of the backlight source is achieved, the harm of blue ray radiation is reduced, and the influence to display result and picture quality is lowered.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight assembly, a mobile terminal and a control method. Background technique [0002] As light emitting diodes (Light Emitting Diode, LED for short) are widely used in lighting sources and backlight liquid crystal displays, people are becoming more and more aware of the harm of blue light radiation to human eyesight. At present, there are two main ways to reduce the blue light radiation of the backlight liquid crystal display: the first is to reduce the blue light radiation by reducing the transmittance of the blue pixel in the red, green and blue RGB sub-pixels of the backlight three primary colors, but this method It will affect the number of color bits of the blue pixel, thereby affecting the display effect; the second is to directly reduce the energy of the blue spectral segment of the backlight, which usually has a negative effect on the saturation of the picture due to changing th...
