Embodiment 1
[0025] Example 1: The above diffusion ink was printed on the light incident surface of a transparent glass substrate. The thickness of the transparent glass substrate was 1 mm, and the printing thickness was 10 μm. After printing, a glass diffusion plate was obtained. / T1720-1979 Paint Film Adhesion Determination Method" to carry out the adhesion test, the test results are recorded in Table 1, prepare LED light source, glass light guide plate, liquid crystal screen, glass back plate and the glass diffuser plate made in this example and other components , install it by conventional means, and make a liquid crystal display screen; after power-on, test the screen brightness of each position of the liquid crystal display screen, and the test results are recorded in Table 2.
Embodiment 2
[0026] Example 2: Mix the above diffusion ink and quantum dot powder uniformly according to the mass ratio of 100:5 to 15, and then print the mixture on the light incident surface of the transparent glass substrate, the printing thickness is 10 μm, and the printing layer is dotted Array distribution, glass quantum dot diffusion plate is obtained after printing, and the dot matrix printing layer formed after printing is subjected to adhesion test according to "GB / T 1720-1979 Paint Film Adhesion Determination Method", and the test results are recorded in Table 1. Prepare LED The light source, liquid crystal screen, glass backplane, and the glass quantum dot diffusion plate made in this embodiment have quantum dot powder in the printed layer, and the printing effect is equivalent to the light guiding effect of the glass light guide plate, so the glass guide plate is omitted. After the power is turned on, the screen brightness of each position of the liquid crystal display screen i...
