Blue phase liquid crystal displays (BPLCDs) have attracted considerable attention in recent years because of its many advantages. However, BPLCDs exhibit narrow temperature range, high driving voltage, and tough process. In our works, polymer‐stabilized technology using newly optimized BPLC material was applied to enlarge BP temperature range. In order to overcome high driving voltage, 2D1G design was used to apply conventional source driver IC for cost. Furthermore, novel groove cell structure which could gain more effective electric field without adding special masks for the groove was successfully implemented. Finally, 10‐inch BPLCDs was demonstrated by optimization of ODF process.

Since 1981, blue phase liquid crystal (BPLC) was regarded as optical isotropy and high contrast ratio (CR) should be achieved easily. However, low CR of BPLC display was reported in all literatures. Here, we show BPLC is non-ideal optical isotropy which leads to poor CR. In our report, BPLC not only revealed primary structure of double-twist cylinder and secondary structure of lattice but also revealed tertiary structure of self-alignment on electrode surface. This finding will be useful to improve CR and inspire researches in display industry and academics.

In this paper, we reported blue phase liquid crystal (BPLC) is not only a non-ideal optical isotropic, but also self-assembly along with electrode. The self-assembly was carefully verified by luminescent colorimeter system. Result showed that BPLC selfassembly along with electrode of in-panel switching cell. We believe this findings will inspire the improvement of light leakage of BPLC.
