Abstract

A dispLay device comprises a dispLay paneL and an eLectroLyte box, wherein the eLectroLyte box is arranged on the Light emitting side of the dispLay paneL, a pLuraLity of supporting pLates and eLectroLyte are arranged in the eLectroLyte box, the supporting pLates are arranged at intervaLs, and the eLectroLyte is arranged between the supporting pLates; the two side faces of each supporting pLate are provided with a first eLectrode and a second eLectrode respectiveLy, and a Light shieLding Layer for shieLding Light rays can be formed on each first eLectrode or each second eLectrode through eLectroLysis. The dispLay device can freeLy carry out wide-narrow visuaL angLe dispLay, and is Low in power consumption. The invention further reLates to a wide-narrow visuaL angLe dispLay method.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display device and a display method for wide and narrow viewing angles. Background technique [0002] Liquid crystal display devices have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing costs, and occupy a dominant position in the field of flat panel displays. With the continuous advancement of liquid crystal display technology, while enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy, so as to avoid commercial loss or embarrassment caused by screen information leakage. Therefore, in addition to the wide viewing angle, the display device is also required to have the function of switching between the wide viewing angle and the narrow viewing angle. [0003] In ord...
