Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] like Figure 1-3 As shown in , a backlight liquid crystal module without light source, including a light guide plate 2, the light guide plate 2 is clamped in the backlight plastic frame 1, and the plane edge of the light guide plate 2 is glued with double-sided tape 3 for sticking the liquid crystal LED , the notch side plane of the backlight plastic frame 1 is provided with a light slot 4 , a plurality of LED lights 5 are fixedly installed in the light slot 4 , and the plurality of LED lights 5 are linearly electrically connected to the flexible circuit board 6 .
[0017] As a further improvement to the above solution, the LED lamp 5 is electrically connected to the flexible circuit board 6 by means of soldering to provide a welding area 7 to connect the conduction circuits of several LED lamps.
[0018] As a further improvement to the above solution, the flex...

The invention discloses a light-source-free backlight liquid crystal module. The light-source-free backlight liquid crystal module comprises a light guide plate, the light guide plate is clamped in abacklight rubber frame, double-sided adhesive tape is adhered to the plane edge of the light guide plate and is used for bonding a liquid crystal LED, the side plane of a notch of the backlight rubberframe is provided with a lamp groove, and a plurality of LED lamps are fixedly arranged in the lamp groove and are linearly and electrically connected to a flexible circuit board. According to the light-source-free backlight liquid crystal module, a backlight assembly technological structure is adopted, the cost is lowered, the light display uniformity of the module is reduced, and the service life is prolonged by one year; light rays with different colors under different spectrums from the ultraviolet spectrums to the infrared spectrum can be emitted from the LED lamps, and particularly thetechnical problem that the existing LED lamps cannot emit white light can be solved; and the processing difficulty and the assembling difficulty of the backlight are also lowered, the productivity andthe efficiency are greatly improved, and meanwhile, the phenomenon that the LED lamp light becomes dark yellow can be avoided.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display screens of electronic products, in particular to a backlight liquid crystal module without a light source. Background technique [0002] The backlight is the light source for the LCD panel, which is mainly composed of a light source, a light guide plate, an optical film, and a plastic plate. [0003] Liquid crystal display is a passive light-emitting element. The display screen itself does not emit light, but is illuminated by the backlight system below it. The combination of the backlight source and the liquid crystal display screen constitutes the liquid crystal display module. [0004] Due to some inherent deficiencies of CCFL (cold cathode fluorescent lamp) backlight technology and products on traditional LCD display devices, such as narrow color gamut, low energy utilization rate, high power consumption and short lifespan, etc. For this reason, in the field, technicians have b...
