The invention provides a negative field sequential liquid crystal display device. The negative field sequential liquid crystal display device comprises a first negative field sequential liquid crystal display element and a second negative field sequential liquid crystal display element, wherein the first negative field sequential liquid crystal display element and the second negative field sequential liquid crystal display element are mutually compensated. The invention further provides a driving method of the negative field sequential liquid crystal display device. The negative field sequential liquid crystal display device and the driving method thereof are high in mass producibility, simple in process, low in cost and good in display effect; and according to product requirement, the work temperature range can be widened, or the display content can be increased.
Description
technical field [0001] The invention relates to a color liquid crystal display device, in particular to a negative field sequential liquid crystal display device and a driving method thereof. Background technique [0002] Most of the existing negative field sequential products adopt TN (Twist Nematic, twisted nematic liquid crystal) or VA (Vertical Array, vertical alignment) negative scheme. TN negative scheme, due to dispersion and other reasons, the background color will appear dark red or dark blue according to the amount of delay, the background color transmittance is high, and the contrast is low; VA negative scheme, due to the need for field sequence For fast response speed, it is necessary to reduce the thickness of the box to meet the requirements of product response time. The small box thickness is difficult to process, the transmittance is low, the NTSC (National Television System Committee, National Television System Committee) value is low, and the feasibility of...
