The invention discloses a backlight module. The backlight module comprises at least two groups of light emitting diodes different in color temperatures, wherein the color temperature of at least one group of light emitting diodes is higher than a preset color temperature comfortable to human eyes, and the color temperature of at least one group of light emitting diodes is lower than the preset color temperature. In addition, the invention also discloses a display module and an electronic apparatus. The backlight module, the display module and the electronic apparatus are provided with multiple groups of light emitting diodes different in color temperature, so that the light emitting diodes with the color temperature higher than the preset color temperature can improve the color rendering property; the overall color temperature can be reduced by combining the light emitting diodes with the color temperature higher than the preset color temperature and the light emitting diodes with the color temperature lower than the preset color temperature, so that the color temperature is approximate to the preset color temperature and even matched with the preset color temperature, the human eyes can feel more comfortable, and the user experience is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a display module and an electronic device. Background technique [0002] Because the backlight module of the display module of the existing electronic device is an artificial light source, in order to increase the color rendering, the light source with a higher color temperature is used, and the eyes will feel uncomfortable when used for a long time. Contents of the invention [0003] The present invention aims to solve at least one of the problematic technical problems existing in the prior art. Therefore, the present invention needs to provide a backlight module, a display module and an electronic device. [0004] The backlight module according to the embodiment of the present invention includes: at least two groups of light-emitting diodes with different color temperatures, wherein the color temperature of at least one group of light-emitting diodes is ...
