Description
Technical Field
The present invention relates to display technologies, and in particular, to a method for manufacturing a liquid crystal display, a cell thickness calculating device, and a readable storage medium.
Background
At present, the off-state output rate of a liquid crystal display can only reach an extreme value within a certain wavelength band due to the dispersion problem of liquid crystal molecules, a polarizer and the like.
Taking a normally black mode reflective liquid crystal display as an example, as shown in fig. 1 and 2, when the cell thickness is R1, the off-state reflectance spectrum of the liquid crystal display is as shown by a solid line LC _ R1, which has an extremely low off-state reflectance in the red wavelength band, but has a high off-state reflectance in both the blue wavelength band and the green wavelength band; when the cell thickness is R2, the off-state reflectance spectrum of the lcd is as shown by the solid line LC _ R2, which has a very low off-state reflectance in the green wavelength band, but a high off-state reflectance in both the blue and red wavelength bands; when the cell thickness is R3, the off-state reflectance spectrum of the lcd is very low in the blue band, but high in both the red and green bands, as shown by the solid line LC _ R3. Because the normally black mode reflective liquid crystal display cannot have extremely low off-state reflectivity in a red light waveband, a green light waveband and a blue light waveband all the time, the normally black mode reflective liquid crystal display cannot be completely black in an off state, the off-state effect is poor, the contrast ratio is low, and meanwhile, the off-state reflectivity difference between different wavebands is large, so that the normally black mode reflective liquid crystal display has a serious color cast problem and low NTSC (liquid crystal display) is caused.
Similarly, the off-state transmittance of the normally black mode lcd can only reach a very low value in a certain band, the off-state reflectance of the normally white mode lcd can only reach a very high value in a certain band, and the off-state transmittance of the normally white mode lcd can only reach a very high value in a certain band.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Example one
As shown in fig. 3, a method for fabricating a liquid crystal display includes:
step 1: establishing an off-state emergent spectrum-box thickness correlation model according to the off-state emergent spectrums of a plurality of common liquid crystal displays and the corresponding box thicknesses thereof;
in this step 1, the cell thickness refers to the thickness of the liquid crystal layer 3 in the liquid crystal display.
The off-state emergent spectrum refers to an emergent rate curve of light rays on different wave bands after passing through an unpowered liquid crystal display (a normally black mode is a black state, and a normally white mode is a white state), and comprises an off-state reflectivity curve and an off-state transmittance curve.
As shown in fig. 1 and 5-7, the liquid crystal display includes a color film substrate 1 and an array substrate 2 which are attached to each other in an up-down opposite manner, a liquid crystal layer 3 is filled between the color film substrate 1 and the array substrate 2, an RGB color film layer 12 is disposed on one surface of a first substrate 11 of the color film substrate 1 facing the array substrate 2, and a TFT array layer 22 is disposed on one surface of a second substrate 21 of the array substrate 2 facing the color film substrate 1; the RGB color film layer 12 includes a plurality of RGB pixels, each of which is composed of an R sub-pixel, a G sub-pixel, and a B sub-pixel.
As shown in fig. 1, the general liquid crystal display refers to a conventional liquid crystal display whose cell thickness (thickness of the liquid crystal layer 3) is uniformly equal everywhere between the R region corresponding to the R sub-pixel, the G region corresponding to the G sub-pixel, and the B region corresponding to the B sub-pixel.
The step 1 specifically comprises:
step 1.1: respectively solving and obtaining Jones matrixes of a plurality of common liquid crystal displays, wherein each common liquid crystal display has different box thicknesses;
in step 1.1, if the manufactured required liquid crystal display is in a normally black mode, the normal liquid crystal display used for solving the jones matrix is also in a normally black mode, and if the manufactured required liquid crystal display is in a normally white mode, the normal liquid crystal display used for solving the jones matrix is also in a normally white mode.
When solving the Jones matrix, firstly, optical parameters (such as transmittance curve of a polaroid, dispersion curve of a compensation film, dispersion curve of liquid crystal and the like) of materials required by calculation of the Jones matrix in each common liquid crystal display are detected and obtained, then the optical parameters of the required materials are input into Jones matrix calculation software, and the Jones matrix corresponding to each common liquid crystal display is solved by the software.
Step 1.2: calculating the off-state emergent spectrum of each common liquid crystal display according to each obtained Jones matrix;
as described above, the estimated off-state emission spectrum substantially has two spectral curves, one is an off-state reflectance curve, and the other is an off-state transmittance curve.
Taking a normally black mode reflective liquid crystal display as an example, as shown in fig. 2, the solid lines LC _ R1, LC _ R2, and LC _ R3 are the off-state reflectance spectra of the conventional liquid crystal display corresponding to the estimated cell thicknesses R1, R2, and R3, respectively.
Step 1.3: and establishing an off-state emergent spectrum-box thickness correlation model according to the obtained off-state emergent spectrum and the corresponding box thickness.
In step 1.3, the off-state emergent spectrum-box thickness correlation model includes an R-band off-state emergent rate-box thickness correlation model, a G-band off-state emergent rate-box thickness correlation model and a B-band off-state emergent rate-box thickness correlation model after light passes through an unpowered common liquid crystal display.
In a specific modeling method, the step 1.3 specifically includes:
step 1.3.1: respectively obtaining R-band off-state emergence rate, G-band off-state emergence rate and B-band off-state emergence rate of each common liquid crystal display from each obtained off-state emergence spectrum;
in step 1.3.1, if the required liquid crystal display is a reflective type, the obtained reflectivity is the off-state reflectivity of the R waveband, the off-state reflectivity of the G waveband and the off-state reflectivity of the B waveband; if the desired liquid crystal display is made transmissive, then R-band off-state transmittance, G-band off-state transmittance, and B-band off-state transmittance are obtained.
For convenience of calculation, if the required lcd is manufactured in a normally black mode, the minimum or average off-state reflectance/transmittance of each wavelength band in the off-state emission spectrum can be, but is not limited to, used as the off-state emission rate of the corresponding wavelength band, such as: taking the lowest or average off-state reflection/transmittance of a red light waveband as the off-state emergence rate of the R waveband, taking the lowest or average off-state reflection/transmittance of a green light waveband as the off-state emergence rate of the G waveband, and taking the lowest or average off-state reflection/transmittance of a blue light waveband as the off-state emergence rate of the B waveband; if the desired lcd is manufactured in normally white mode, the highest or average off-state reflectance/transmittance of each wavelength band in the off-state emission spectrum can be, but not limited to, used as the off-state emission rate of the corresponding wavelength band, such as: the highest or average off-state reflection/transmittance of the red light band is taken as the off-state emission rate of the R band, the highest or average off-state reflection/transmittance of the green light band is taken as the off-state emission rate of the G band, and the highest or average off-state reflection/transmittance of the blue light band is taken as the off-state emission rate of the B band.
Of course, the off-state emergence rate of the R-band, the off-state emergence rate of the G-band, and the off-state emergence rate of the B-band for modeling are not limited to the minimum value, the maximum value, or the average value, and different selection methods, such as weighting, may be adopted according to actual requirements.
Step 1.3.2: and respectively establishing an R-waveband off-state emergence rate-box thickness correlation model, a G-waveband off-state emergence rate-box thickness correlation model and a B-waveband off-state emergence rate-box thickness correlation model by adopting regression equations according to the obtained R-waveband off-state emergence rate, G-waveband off-state emergence rate, B-waveband off-state emergence rate and the corresponding box thickness discrete points.
In this step 1.3.2, the discrete points for modeling include: r-band off-state emittance-box thick discrete points, G-band off-state emittance-box thick discrete points, and B-band off-state emittance-box thick discrete points.
Specifically, the regression equation established by discrete points is only one specific modeling method listed for the convenience of understanding the present application, and the scope of the present application shall include other existing modeling methods.
Step 2: according to the established off-state emergent spectrum-box thickness correlation model, when the required R-band off-state emergence rate, G-band off-state emergence rate and B-band off-state emergence rate are respectively achieved, a first box thickness h1, a second box thickness h2 and a third box thickness h3 which correspond to each other are calculated;
in step 2, if the required lcd is a reflective lcd of normally black mode, the required lcd is very low R-band off-state reflectivity, G-band off-state reflectivity and B-band off-state reflectivity; if the manufactured required liquid crystal display is of a transmission type in a normally black mode, the required liquid crystal display is extremely low R-band off-state transmittance, G-band off-state transmittance and B-band off-state transmittance; if the required liquid crystal display is made to be a reflection type of a normally white mode, the required reflectivity is extremely high R-band off-state reflectivity, G-band off-state reflectivity and B-band off-state reflectivity; if the desired liquid crystal display is made in a normally white mode, then extremely high R-band off-state transmittance, G-band off-state transmittance, and B-band off-state transmittance are desired.
In order to optimize the off-state effect of the required liquid crystal display, when the first box thickness h1, the second box thickness h2 and the third box thickness h3 are calculated, optimally, the off-state emission rate of the R-band, the off-state emission rate of the G-band and the off-state emission rate of the B-band all adopt the lowest value or the highest value of the off-state reflectivity or the off-state transmittance in the off-state emission spectrum-box thickness correlation model.
However, in the specific implementation, the process precision of each manufacturer is different, and therefore, the R-band off-state emission rate, the G-band off-state emission rate, and the B-band off-state emission rate used in calculating the box thickness may also be lower values or higher values of the off-state reflectance or the off-state transmittance in the off-state emission spectrum-box thickness correlation model, where if the required manufactured liquid crystal display is in the normally black mode, the lower value of the off-state reflectance or the off-state transmittance is preferably between 0% and 10%, and if the required manufactured liquid crystal display is in the normally white mode, the higher value of the off-state reflectance or the off-state transmittance is preferably between 90% and 100%, depending on the process precision of each manufacturer.
Taking a normally black mode reflective liquid crystal display as an example, if the three off-state reflection spectra shown in fig. 2 are used to manufacture a desired liquid crystal display, it can be seen that when the cell thickness is R1, the off-state reflectance of the conventional liquid crystal display in the red light band is very low, when the cell thickness is R2, the off-state reflectance of the conventional liquid crystal display in the green light band is very low, and when the cell thickness is R3, the off-state reflectance of the conventional liquid crystal display in the blue light band is very low, and then, in order to make the desired liquid crystal display have very low off-state reflectance in the red light band, the green light band, and the blue light band at the same time, the desired liquid crystal display can be manufactured according to the first cell thickness h1= R1, the second cell thickness h2= R2, and the third cell thickness h3= R3.
And step 3: in accordance with the calculated first, second and third box thicknesses h1, h2 and h3, a desired liquid crystal display is fabricated having a first box thickness h1 in the R region corresponding to the R sub-pixel, a second box thickness h2 in the G region corresponding to the G sub-pixel and a third box thickness h3 in the B region corresponding to the B sub-pixel.
In step 3, except for the required liquid crystal display, the materials such as the polarizer, the substrate glass, the liquid crystal molecules, the ITO, the RGB ink and the like have the same specifications as those of the common liquid crystal display except that the cell thicknesses of the R region, the G region and the B region are not uniform.
Taking a normally black mode reflective lcd as an example, when the R region of the desired lcd has a first cell thickness h1= R1, the G region has a second cell thickness h2= R2, and the B region has a third cell thickness h3= R3, the off-state reflectance spectrum of the desired lcd is as shown in fig. 4, the solid line LC _ R is the off-state reflectance spectrum of the R region, the solid line LC _ G is the off-state reflectance spectrum of the G region, and LR _ B is the off-state reflectance spectrum of the B region, and it can be seen that the R region, the G region, and the B region all maintain extremely low off-state reflectance in the red, green, and blue wavelength bands simultaneously.
In a specific implementation, the R region, the G region, and the B region of the required liquid crystal display can reach the first box thickness h1, the second box thickness h2, and the third box thickness h3 respectively by controlling the heights of the corresponding regions of the surface, facing the liquid crystal layer 2, of the color film substrate 1 and/or the array substrate 2.
In a specific implementation manner, as shown in fig. 5, R sub-pixels, G sub-pixels, and B sub-pixels in the RGB color film layer 12 of the color film substrate 1 respectively have different ink thicknesses, so that an R region, a G region, and a B region of a required liquid crystal display respectively reach a first box thickness h1, a second box thickness h2, and a third box thickness h 3.
In another specific implementation, as shown in fig. 6, the TFT array layer 22 of the array substrate 2 is covered with an OC planarization layer 23, and the OC planarization layer 23 has different OC thicknesses between the R region, the G region, and the B region, so that the R region, the G region, and the B region of the desired liquid crystal display reach the first cell thickness h1, the second cell thickness h2, and the third cell thickness h3, respectively.
In yet another specific implementation manner, as shown in fig. 7, R sub-pixels, G sub-pixels, and B sub-pixels in the RGB color film layer 12 of the color film substrate 1 respectively have the same or different ink thicknesses, and meanwhile, an OC planarization layer 23 covers the TFT array layer 22 of the array substrate 2, and the OC planarization layer 23 has the same or different OC thicknesses between an R region, a G region, and a B region, so that the R region, the G region, and the B region of the required liquid crystal display respectively reach the first box thickness h1, the second box thickness h2, and the third box thickness h 3.
The manufacturing method makes the box thickness of the needed liquid crystal display be uniform and equal in each position, different sub-pixels are matched with different box thicknesses to control the needed liquid crystal display to have the needed off-state emergence rate on a red light wave band, a blue light wave band and a green light wave band simultaneously, and compared with the existing common liquid crystal display with the same box thickness in each position, the off-state effect of the liquid crystal display can be improved, so that the liquid crystal display in a normally black mode is darker in an off state, and the liquid crystal display in a normally white mode is whiter in the off state, and the purposes of high contrast, high NTSC and low color cast are achieved.
The manufacturing method is especially suitable for twisted liquid crystal displays with off-state effect sensitive to the cell thickness, but is also suitable for non-twisted liquid crystal displays.
Example two
As shown in fig. 5-7, a liquid crystal display has a first cell thickness in the R region corresponding to the R sub-pixel, a second cell thickness in the G region corresponding to the G sub-pixel, and a third cell thickness in the B region corresponding to the B sub-pixel to simultaneously have the desired R-band off-state exit power, G-band off-state exit power, and B-band off-state exit power.
