[0029] Light guide plate layer, the light guide plate layer includes a light guide plate;

[0030] The light source layer is located below the light guide plate layer;

[0031] Quantum dot film layer, which is placed above the light guide plate layer.

[0032] Example 1

[0033] Figure 1 This is a schematic diagram of the backlight module structure according to an embodiment of this application. The following will be combined with... Figure 1 The backlight module structure of the embodiments of this application will be described in detail.

[0034] In one exemplary embodiment, the backlight module of this application includes a light guide plate layer 103.

[0035] In one exemplary embodiment, the light guide plate layer 103 includes a light guide plate.

[0036] In one exemplary embodiment, the light guide plate utilizes optical-grade acrylic / PC sheets. Light guide points are then printed onto the bottom surface of the optical-grade acrylic sheet using a high-tech material with extremely high refractive index and no light absorption, employing techniques such as laser engraving, V-shaped cross-grid engraving, and UV screen printing. The optical-grade acrylic sheet absorbs light emitted from a light source, causing it to linger on its surface. When light strikes each light guide point, the reflected light diffuses at various angles, disrupting the reflection conditions and exiting from the front of the light guide plate. By using light guide points of varying density and size, the light guide plate can emit light uniformly.

[0037] In one exemplary embodiment, the surface of the light guide plate includes a bump and / or groove structure, which is designed to improve the scattering effect of light, thereby achieving more uniform light output.

[0038] In one exemplary embodiment, the backlight module of this application further includes a light source layer 102.

[0039] In one exemplary embodiment, the light source layer 102 is disposed below the light guide plate layer 103.

[0040] In one exemplary embodiment, the light source layer 102 is an LED lamp.

[0041] In one exemplary embodiment, the LED light is mounted on the FPC as needed.

[0042] In one exemplary embodiment, the backlight module of this application further includes a quantum dot film layer 104.

[0043] In one exemplary embodiment, a quantum dot film layer 104 is disposed above a light guide plate layer 103.

[0044] In one exemplary embodiment, the quantum dot film 104 is formed by coating on a light guide plate.

[0045] In one exemplary embodiment, the quantum dot film 104 is formed by coating a quantum dot solution onto a light guide plate.

[0046] In one exemplary embodiment, the quantum dot solution is composed of quantum dot material and polymer.

[0047] In one exemplary embodiment, a quantum dot, also known as a semiconductor nanocrystal, is a semiconductor crystal particle composed of hundreds to thousands of atoms, typically ranging in size from a few nanometers to tens of nanometers. When a quantum dot is excited by external energy (light or electricity), it emits light of a specific frequency. The frequency of the emitted light changes with the size of the semiconductor, thus the color of the emitted light can be controlled by adjusting the size of the nano-semiconductor. Its emitted color can cover the entire visible spectrum from blue to red, exhibiting characteristics such as high color purity, long lifespan, and good stability.

[0048] In one exemplary embodiment, when a quantum dot is excited by external energy (such as light energy), an electron jumps from the valence band to the conduction band, and then the electron returns from the conduction band to the valence band and emits light of a specific wavelength.

[0049] In one exemplary embodiment, the quantum dot film 104 is formed by printing on a light guide plate.

[0050] In one exemplary embodiment, the quantum dot film 104 is formed by screen printing on a light guide plate.

[0051] In one exemplary embodiment, the quantum dot film 104 is formed by screen printing a quantum dot solution onto a light guide plate.

[0052] In one exemplary embodiment, the backlight module of this application further includes a reflective layer 101.

[0053] In one exemplary embodiment, the reflective layer 101 is disposed below the light source layer 102.

[0054] In one exemplary embodiment, the reflective layer 101 includes a reflective sheet.

[0055] In one exemplary embodiment, the reflective layer 101 is used to reflect the light from the light source layer 102 in the direction of the light guide plate.

[0056] In one exemplary embodiment, the backlight module of this application embodiment achieves higher purity of the emission spectrum and higher energy utilization. The color of the emitted light can also be precisely controlled by controlling the thickness of the quantum dot film 104.
