Embodiment 1
[0046] Embodiment 1 provides a side-entry backlight module, which includes a backlight panel main body, a light source, a light source moving module, and a shading module.
[0047] Please refer to the attachedfigure 1 The main body of the backlight panel includes a first substrate 1 and a second substrate 2 for fixing the light guide plate to be inspected, and the first substrate 1 and the second substrate 2 are detachably connected to form other components of the backlight module , such as the accommodation space for the light source, the light source moving module and the shading module; the first substrate 1 and the second substrate 2 connected in a detachable manner are not integral structures and can be placed separately during transportation for convenient transportation.
[0048] Please refer to attached figure 2 and image 3 , the light source moving module is arranged on the front side of the second substrate 2, the light source moving module includes a light source...
Embodiment 2
[0061] This embodiment provides a liquid crystal display device, which includes a light guide plate and the above-mentioned edge-type backlight module. The light guide plate is fixed on the first substrate 1 and is arranged opposite to the light source 4 .
[0062] Wherein, for the specific structure of the side-type backlight module of this embodiment, please refer to the relevant descriptions of the previous embodiments, and details are not repeated here.
[0063] It should be noted that, in this embodiment, the light guide plate is fixedly installed on the first substrate through a plurality of positioning pins 3. In this embodiment, a plurality of positioning pins 3 are used to fix the light guide plate on the first substrate. The positioning pins 1 Cooperate with the card slot of the light guide plate to ensure that the light guide plate will not shake on the first substrate.
Embodiment 3
[0065] This embodiment provides an optical inspection method for a light guide plate, which is implemented based on the above-mentioned side-entry backlight module, and the method includes the following steps:
[0066] S101, fixing and installing the light guide plate to be inspected on the first substrate through a plurality of positioning pins;
[0067] S102, turning the knob clockwise, the knob drives the turntable 6 to rotate;
[0068] S103, the turntable drives two L-shaped levers 8 to make a fan-shaped movement around the rotating shaft 10 through the two connecting rods 7;
[0069] S104, the projections 83 of the two L-shaped levers respectively fan-shaped swing, and at the same time jack up the light source support frame 5;
[0070] S105, the light source support frame 5 drives the light source 4 to move upward in a direction perpendicular to the light source support frame 5, so that the light source is close to the light incident side of the light guide plate;
