The invention discloses a field sequence driving liquid crystal display circuit and a display device. The field sequence driving liquid crystal display circuit comprises a power supply circuit, a control circuit, a network communication circuit, an illumination sensor and a programmable logic device circuit, wherein the control circuit generates module light source data according to the ambient light brightness; and the display information is stored in a flash memory area of the control circuit, the control circuit reads the display information and collects module light source data generated by ambient light to form display device driving data, the display device driving data is stored in a cache area, and the display device driving data and a write-in instruction are sent to the programmable logic device circuit. The programmable logic device circuit is provided with two storage areas for receiving the driving data of the display device and driving the display device to work accordingto the driving data of the display device, thus data seamless cache and processing can be realized, more liquid crystal display modules can be driven, intelligent energy-saving display can be achieved, and the brightness can be automatically adjusted.
Description
technical field [0001] The invention relates to the technical field of liquid crystal driving, in particular to a field sequence driving liquid crystal display circuit and a display device thereof. Background technique [0002] FSLCD (Field Sequential Color LCD, Field Sequential Driven Color Liquid Crystal Display Module) LCD module is a kind of liquid crystal display module that does not require color filters, and uses RGB (red, green, blue) LEDs with timing switching to emit red, green, and Color mixing caused by blue light, and then display color. Its switching speed exceeds the perception frequency of the human eye (60Hz), so the human brain will stack the picture effects together due to the persistence of vision to form the feeling of a full-color picture. [0003] Because FSLCD does not need a filter, the displayed color is directly synthesized by the RGB backlight, so the display brightness can be very high, reaching 1000cd / m 2 Above, and the light is soft, it is wi...
