Abstract

The invention discloses a conjugated polymer, a conductive composition and a liquid crystal display panel. The conjugated polymer comprises a plurality of 3,4-ethylenedioxythiophene groups, and a plurality of electron withdrawing groups grafted to the tail ends of the plurality of 3,4-ethylenedioxythiophene groups. The conjugated polymer provided by the invention is grafted to the tail ends of theplurality of 3,4-ethylenedioxythiophene groups through the plurality of electron withdrawing groups, so that energy level difference between valence bands and conduction bands of the 3,4-ethylenedioxythiophene groups is reduced, the electron transmission ability is improved, and the conductivity is improved.

Description

technical field [0001] The present invention relates to conductive materials, in particular to a conjugated polymer, a conductive composition and a liquid crystal display panel. Background technique [0002] Existing liquid crystal display panels mainly use indium tin oxide materials as electrodes, but the cost of indium elements in indium tin oxide materials is expensive, and the fragility of indium tin oxide materials also limits the application of indium tin oxide materials in flexible displays. Therefore, some liquid crystal display panels use poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid ((poly(3,4-ethylenedioxythiophene): poly-(styrenesulfonate); PEDOT:PSS) to replace oxidation Indium tin material to solve the above problems. [0003] However, the electrical conductivity of the PEDOT:PSS material is lower than that of the ITO material, so it cannot be applied to existing displays. Therefore, it is necessary to provide a conjugated polymer, a conductive c...
