Description
Technical Field
The invention relates to a novel orientation method of an LCoS liquid crystal screen, and belongs to the technical field of LCoS liquid crystal screens.
Background
The manufacturing process flow of the conventional LCoS (liquid crystal on silicon) liquid crystal screen comprises the following steps: the method comprises the steps of respectively cleaning the ITO glass and the LCoS chip, preparing a photo-alignment layer and photo-aligning, coating ultraviolet curing frame glue containing spacers on the glass substrate, aligning and attaching the ITO glass and the LCoS chip, irradiating ultraviolet light to cure the frame glue, filling liquid crystal and the like. By adopting the conventional manufacturing process flow and utilizing the pixelation control technology of optical orientation, pixelation is firstly carried out on the ITO glass and the LCoS chip respectively, and then two blocks of the ITO glass and the LCoS chip are basically aligned and attached, so that the consistent orientation states of corresponding pixels of an upper substrate and a lower substrate of the LCoS liquid crystal screen cannot be ensured, and the pixel-level orientation control of the LCoS liquid crystal screen cannot be realized. Those skilled in the art have tried new solutions, but the problem has not been solved well, and therefore, there is an urgent need for a new solution to solve the technical problem.
Disclosure of Invention
In order to overcome the defect that the conventional LCoS liquid crystal screen manufacturing process cannot realize pixel-level orientation control of the LCoS liquid crystal screen, the invention provides a mode of sealing a box first and then orienting, and after finishing coating and sealing a box of a light orientation agent, the light orientation treatment is carried out outside the LCoS liquid crystal box by utilizing a pixel control technology of light orientation so as to obtain an orientation state with consistent pixels of ITO glass and an LCoS chip, thereby realizing the orientation control of pixel-level precision of the LCoS liquid crystal screen.
The invention provides an off-screen optical orientation method for an LCoS liquid crystal screen aiming at the problems in the prior art, and the manufacturing process flow of the 'box sealing and orientation after' off-screen optical orientation LCoS liquid crystal screen is as follows:
1) respectively cleaning the ITO glass and the LCoS chip;
2) preparing a photo-alignment layer;
3) mixing the spacer with ultraviolet curing glue;
4) coating ultraviolet curing frame glue containing spacers on a glass substrate;
5) aligning and laminating the ITO glass and the LCoS chip, and carrying out ultraviolet irradiation curing on the ultraviolet curing frame glue containing the spacers;
6) vertically irradiating the LCoS chip by polarized ultraviolet light on one side of the glass substrate outside the sealed liquid crystal screen to carry out light orientation; 7) and finally, filling liquid crystals to obtain the liquid crystal screen. The scheme firstly seals the LCoS (liquid crystal on silicon) liquid crystal box, and then carries out optical orientation on an optical orientation layer of the LCoS liquid crystal screen from the outside of the screen. The method is completely different from the traditional method of the prior liquid crystal screen for orienting the liquid crystal molecular layer, namely the method for respectively orienting the upper substrate and the lower substrate of the liquid crystal screen and then sealing the box.
As an improvement of the invention, in the step 3), the spacers and the ultraviolet curing glue are mixed uniformly according to the proportion of 5-35% by mass, and then bubbles in the glue are removed in a vacuum environment, and in the step 4), the ITO glass is coated with frame glue by using a dispenser filled with ultraviolet curing frame glue containing the spacers.
As an improvement of the present invention, the step 6) is specifically as follows: vertically irradiating polarized ultraviolet light from the side of the ITO glass to the prepared LCoS liquid crystal box to carry out light orientation outside the screen; or the prepared LCoS liquid crystal box is arranged below the light orientation device, and polarized ultraviolet light vertically irradiates on the LCoS liquid crystal box from the ITO glass side through a mask plate which is aligned with the LCoS chip to carry out light orientation outside the screen; or the prepared LCoS liquid crystal box is arranged below the optical orientation device to carry out the light orientation outside the screen, the polarized ultraviolet light vertically irradiates on the LCoS liquid crystal box from the ITO glass side through a mask plate which is aligned with the LCoS chip, the polarized incident ultraviolet light in the specific polarization direction vertically irradiates on the pixel needing the orientation in the specific direction by adjusting the included angle between the LCoS chip and the incident polarized ultraviolet light polarization direction and matching the use of the mask plate, and the orientation in any direction of the pixel level precision is realized by adjusting the light orientation outside the screen for many times.
According to the scheme, different working modes can be generated by using different orientation agents in the manufacturing process, and the step of off-screen light orientation requires that polarized ultraviolet light is vertically incident on an LCoS liquid crystal box to be oriented so as to ensure the consistent orientation state of corresponding pixels of ITO glass and an LCoS chip. Under the action of the mask plate, the orientation with pixel level precision can be realized.
Compared with the prior art, the invention has the following beneficial effects: because the off-screen optical orientation technology adopts a mode of 'sealing the box first and then orienting', after finishing coating and sealing the optical orientation agent, the optical orientation treatment is carried out outside the LCoS liquid crystal box by utilizing the pixel control technology of optical orientation, so that the orientation state of corresponding pixels of ITO glass and an LCoS chip can be obtained, the orientation of pixel precision is realized, and the problem that the conventional LCoS liquid crystal screen manufacturing process can not realize the pixel-level orientation control of the LCoS liquid crystal screen is solved; the scheme adopts a parallel light orientation agent to manufacture a light orientation layer and is filled with a positive liquid crystal material to realize an anti-parallel (ECB) orientation mode; the scheme is matched with a mask plate to use, so that an anti-parallel (ECB) orientation mode of any orientation direction of pixel-level precision control can be realized, and the alignment problem of corresponding pixels of the ITO glass and the LCoS chip is not required to be considered; the scheme adopts a vertical photo-alignment agent to manufacture a photo-alignment layer and fills a negative liquid crystal material to realize a Vertical Alignment (VA) mode.
