Problems solved by technology

Products using this technology have low efficiency, high energy consumption and poor effect, and are not suitable for industrial mass production
The second is continuous low-voltage technology, which continuously applies a low voltage to the liquid crystal layer. Usually, the voltage is not enough to change the writing marks that have been formed, but when an eraser is used to wipe a certain area, the area is squeezed , the liquid crystal layer in the region becomes thinner
However, in the actual operation process, it is found that the lower voltage is not enough to completely change the liquid crystal state in the squeezed area, which makes the area always leave writing marks, and the partial erasing effect is not ideal.
[0003] With the continuous expansion of the liquid crystal tablet market, the defects of existing liquid crystal tablet functions are also making people more and more urgent for high-quality partial erasing products. Therefore, it is necessary to provide a local erasing effect is better good liquid crystal display device

Embodiment 1

[0030] figure 1 is a schematic structural view of a liquid crystal display device according to an embodiment of the present invention. Such as figure 1As shown, the liquid crystal display device includes a liquid crystal display device, a position detection device 5 and a driving device 7 connected to the liquid crystal display device. The liquid crystal display device includes a first light-transmitting substrate 11 , a first conductive layer 21 , a liquid crystal layer 3 , a second conductive layer 22 , a second light-transmitting substrate 12 , and a light-absorbing layer 4 arranged in sequence. The liquid crystal layer 3 includes a cholesteric liquid crystal 31, a polymer network 32, and a spacer 33, and the spacer 33 is used to separate the first conductive layer 21 from the second conductive layer 22 (the first transparent substrate 11 and the second transparent substrate 11). The substrate 12) supports a specific gap and maintains the flatness of the space. The drivi...

Abstract

The invention discloses a liquid crystal display device with partial erasure effect, a liquid crystal display device, and electronic equipment. The liquid crystal display device comprises a first transmitting substrate, a first conducting layer, a liquid crystal layer, a second conducting layer, and a second transmitting substrate arranged in order; the first conducting layer comprises a pluralityof first conducting wire rods arranged at intervals along a first direction, the second conducting layer comprises a plurality of second conducting wire rods arranged at intervals along a second direction, and the first direction and the second direction are interlaced; the conducting wire rods of the first conducting layer and the second conducting layer are alternately arranged at two sides ofthe liquid crystal layer, thereby forming dot-matrix type pixel points. The electric field states and intensities at two sides of the liquid crystal of various pixel points are controlled through an external driving circuit, thereby controlling a display state of each pixel point; under the effect of the applied electric field, the liquid crystal in the pixel point is translated into a focal conicstate through which all rays can penetrate from a planar state for reflecting the specific wavelength, thereby realizing good partial erasure effect.

Description

technical field [0001] The invention relates to the field of liquid crystal technology, in particular to a liquid crystal display device, a liquid crystal display device and electronic equipment. Background technique [0002] Existing liquid crystal handwriting boards mainly adopt the following two technologies to realize the partial erasing function: the first one is local heating technology, which heats a part of the liquid crystal layer through heat conduction to cause rearrangement. This partial erasing technology generally requires a heating time of 5-10s, and requires a relatively high reaction temperature, usually above 80°C. Products using this technology have low efficiency, high energy consumption and poor effect, and are not suitable for industrialized mass production. The second is continuous low-voltage technology, which continuously applies a low voltage to the liquid crystal layer. Usually, the voltage is not enough to change the writing marks that have been ...
