Embodiment 1-3

[0083] Embodiment 1-3 prepares polymer

[0084] Polymers with corresponding dianhydride and diamine structures as shown in Table 1 were synthesized. Specifically, at room temperature, dissolve 0.01 mole of diamine in 35 g of N,N-dimethylacetamide, stir mechanically, add 0.01 mole of dianhydride in batches after dissolving, and continue to stir and react for 12 hours under nitrogen protection. A transparent and viscous polyamic acid solution with a solid content of about 20% is obtained.

[0085] The obtained polyamic acid solution was left to stand for 24 hours until the air bubbles were eliminated, and then coated on a glass substrate. Thereafter, it is put into a baking device, and the temperature is raised in a nitrogen atmosphere (oxygen solubility is between 0.001%-1%, preferably 0.01%-0.1%). Raise the temperature to 100°C at 5°C / min, stabilize for 60 minutes, then raise the temperature step by step at 5°C / min to 150°C, 200°C, 250°C, and 300°C, and stabilize for 30 minu...

Embodiment 4-6

[0090] Embodiment 4-6 manufactures flexible liquid crystal display device

[0091] The above-mentioned polymer according to embodiment 1-3 is used to make respectively as Figure 1-3 The flexible liquid crystal display device shown, thereby obtaining the flexible liquid crystal display device according to Examples 4-6. According to the flexible liquid crystal display device of embodiment 4-6, the flexible substrate can be used to filter the blue light, thereby reducing or eliminating the damage to the human eye caused by the excessively strong blue light, without additionally increasing the blue light blocking agent in the filter layer. content or additionally form a blue filter layer.

Abstract

The invention provides a flexible liquid crystal display device. The flexible display device comprises a first flexible substrate, a second flexible substrate facing the first flexible substrate and aliquid crystal layer positioned between the first flexible substrate and the second flexible substrate, wherein at least one of the first flexible substrate and the second flexible substrate includesat least one of polymers shown by a formula 1, the formula 1 is shown in the description, and a ring A, a ring R, a ring a and a ring n in the formula 1 are defined as the description. The flexible liquid crystal display device can have a blue light filtering function.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a flexible liquid crystal display device. Background technique [0002] With the demand for miniaturization and portability of display devices, flexible display devices with characteristics such as thinness, light weight, flexibility, and ease of transportation and portability have attracted more and more attention. In order to realize a bendable and flexible display device, a polymer film material is usually used instead of glass to form a substrate of the display device, and then electronic devices are fabricated and an etching process is performed on it. Generally, polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and the like can be used as the polymer film material. [0003] The blue light emitted from the flexible LCD display device may be strong, which will cause the displayed image to be cooler, and at the same time, the excessively stron...
