Problems solved by technology

However, the orientation ability of the alignment polymer polymerized by the existing photosensitive monomer is not good, and the alignment polymer cannot effectively arrange the liquid crystal molecules
When a voltage is applied, the messy liquid crystal molecules need a long reaction time to rotate all the liquid crystal molecules to the preset tilt angle, which greatly affects the display quality of the liquid crystal panel

Embodiment Construction

[0022] The present invention mainly proposes a photosensitive monomer, which can increase the positioning force of the photosensitive monomer to liquid crystal molecules when applied to the manufacturing method of the liquid crystal panel, shorten the process time, and enhance the orientation ability at the same time. The general chemical formulas, preferred embodiments and synthesis methods of the photosensitive monomers will be described below, and then the method of applying these photosensitive monomers to the manufacture of liquid crystal panels will be described.

[0023] Photosensitive monomer:

[0024] The present invention mainly proposes a photosensitive monomer whose central hard core structure has a small dihedral angle or even a coplanar structure. Therefore, not only the ability to align liquid crystal molecules is strong, but the process time can be shortened, and after the photosensitive monomer is polymerized, the ability to align liquid crystal molecules is b...

Description

technical field [0001] The invention relates to a photoelectric device and a manufacturing method thereof, in particular to a photoelectric device using polymer-assisted orientation technology and a manufacturing method thereof. Background technique [0002] In recent years, liquid crystal panels have developed an alignment technology called Polymer-Stabilizing Alignment (PSA). The polar monomers are polymerized into alignment polymers to guide the arrangement of liquid crystal molecules. However, the existing photosensitive monomer polymerized alignment polymers have poor alignment ability, and the alignment polymers cannot effectively arrange liquid crystal molecules. When a voltage is applied, it takes a long time for the disordered liquid crystal molecules to rotate all the liquid crystal molecules to a preset inclination angle, thereby greatly affecting the display quality of the liquid crystal panel. Contents of the invention [0003] The technical problem to be so...
