Embodiment Construction

[0062] The invention provides a display module with a switchable lighting mode design. The display module of the present invention is preferably a liquid crystal display. In one embodiment, the light source of the backlight module adopts white light emitting diodes and cyan light emitting diodes, and uses alternate lighting to switch between different display modes, so that users can adjust to different light emitting modes according to needs.

[0063] figure 1 It is a schematic diagram of an embodiment of the backlight module 130 of the present invention. Such as figure 1 As shown, the backlight module 130 includes a first light source 132 , a second light source 134 and a control module 136 . The light generated by the first light source 132 has a first emission spectrum, and the light generated by the second light source 134 has a second emission spectrum. See figure 2 Schematic diagram of emission spectrum distribution of the first light source and the second light s...

Abstract

The present invention discloses a backlight module possessing light-emitting mode switching design and a display module using the same. The backlight module comprises a first light source, a second light source and a control module, and the light rays generated by the first light source possess a first emission frequency spectrum, wherein the first emission frequency spectrum possesses a first blue light wave crest and a first non-blue light wave crest. The light rays generated by the second light source possess a second emission frequency spectrum, wherein the second emission frequency spectrum possesses a second blue light wave crest and a second non-blue light wave crest, and the intensity peak of the first blue light wave crest is greater than the intensity peak of the second blue light wave crest. The control module controls the first and second light sources according to the design of a first mode and a second mode, under the first mode, lightens the first light source as a backlight source, and under the second mode, controls the first and second light sources to be lightened alternatively according to a timing sequence as the backlight source.

Description

technical field [0001] The present invention relates to a backlight module and a display module using the same; specifically, the present invention relates to a backlight module with a lighting mode switching design and a display module using the same. Background technique [0002] With the advancement of display technology, there are many products that can provide high-quality images. As far as the backlight module is concerned, the way in which fluorescent tubes were used as the backlight in the past has been gradually replaced by light-emitting diodes. Light-emitting diodes have the advantages of high luminous efficiency and long service life. A display using light-emitting diodes as a backlight can reduce the overall volume and achieve a lightweight effect under the same size. [0003] In terms of light emitting methods, commonly used LED backlight modules use blue light-emitting diodes, and the blue light emitted by the blue light-emitting diode chips excites phosphors...
