Problems solved by technology

Since it is still impossible to have extremely low off-state reflectivity in the red, green, and blue light bands at the same time, reflective LCDs in normally black mode cannot be completely black in the off-state, and the off-state effect is not good. The contrast is low. At the same time, due to the large difference in off-state reflectance between different bands, it has a more serious color shift problem and leads to low NTSC
[0004] Similarly, the off-state transmittance of a normally black mode transmissive LCD can only reach an extremely low value in a certain band, and the off-state reflectance of a normally white mode reflective LCD can only reach a certain band. The off-state transmittance of the normally white mode transmissive LCD can only reach a very high value in a certain band

Embodiment 1

[0043] Such as image 3 Shown, a kind of manufacturing method of liquid crystal display comprises:

[0044] Step 1: Based on the off-state emission spectra of multiple common liquid crystal displays and their corresponding cell thicknesses, an off-state emission spectrum-cell thickness correlation model is established;

[0045] In this step 1, the cell thickness refers to the thickness of the liquid crystal layer 3 in the liquid crystal display.

[0046] The off-state emission spectrum refers to the emission rate curves in different bands after the light passes through an unpowered liquid crystal display (the normally black mode is the black state, and the normally white mode is the white state), including the off-state reflectance curve and the off-state reflectance curve. The off-state transmittance curve, because the off-state reflectance curve and the off-state transmittance curve can be converted to each other through a certain value, the off-state reflectance curve can ...

Abstract

The invention discloses a manufacturing method of a liquid crystal display, comprising: step 1: establishing an off-state emission spectrum-cell thickness correlation model; step 2: calculating the required R-band off-state emission rate and G-band off-state emission rate respectively rate and B-band off-state emission rate, corresponding to the thickness of the first box, the second box and the third box respectively; Step 3: Make the required liquid crystal display, and the required liquid crystal display is in the R area corresponding to the R sub-pixel It has a first box thickness, a G area corresponding to the G sub-pixel has a second box thickness, and a B area corresponding to the B sub-pixel has a third box thickness. The manufacturing method can control the required liquid crystal display to have the required off-state emission rate in the red light band, blue light band and green light band at the same time, improve the off-state effect of the liquid crystal display, and achieve high contrast, high NTSC, and low color shift the goal of. The invention also provides a liquid crystal display, a cell thickness calculating device and a readable storage medium.

Description

technical field [0001] The invention relates to display technology, in particular to a manufacturing method of a liquid crystal display, a liquid crystal display, a cell thickness calculation device and a readable storage medium. Background technique [0002] At present, due to the dispersion of liquid crystal molecules and polarizers, the off-state emission rate of liquid crystal displays can only reach an extreme value in a certain wavelength band. [0003] Take the reflective liquid crystal display in normally black mode as an example, such as figure 1 and 2 As shown, when the thickness of the cell is R1, the off-state reflection spectrum of the liquid crystal display is shown by the solid line LC_R1. The reflectivity is high; when the thickness of the cell is R2, the off-state reflectance spectrum of the liquid crystal display is shown by the solid line LC_R2, and its off-state reflectance in the green light band is extremely low, but in the blue and red light bands T...
