Problems solved by technology
However, the liquid crystal display device uses the mode of shutting down and restarting to realize the switching of the working mode, which causes inconvenience to the user to use the liquid crystal display device, and the film sticking method on the liquid crystal display device realizes the switching process of the wide and narrow viewing angle mode is irreversible, and the cost of the anti-peeping film is high. At the same time, it also brings great inconvenience when the user needs the liquid crystal display device to display information to share.

The invention provides a code switching circuit, which comprises an external control unit, a reset unit, a reverse-phase unit, a storage unit, and a time sequence control circuit, wherein the external control unit is used for outputting a first control signal; the reset unit is used for outputting a reset signal according to the first control signal; the reverse-phase unit is used for outputting a second control signal with a reverse phase to the first control signal; the storage unit is used for receiving the first control signal and the second control signal and outputting first code data information or second code data information; and the time sequence control circuit is used for carrying out reset according to the reset signal, acquiring the first code data information or the second code data information from the storage unit and transmitting the information to a display panel to enable the display panel to be switched into a first work mode or a second work mode. The invention also provides a liquid crystal display device. Thus, automatic switching between the first code data information and the second code data information through the time sequence control circuit is realized.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a code switching circuit and a liquid crystal display device. Background technique [0002] Due to the advantages of thinness, energy saving, and no radiation, liquid crystal display devices are currently widely used in electronic equipment such as televisions, personal computers, tablet computers, personal digital assistants (PDAs), mobile phones, and digital cameras. Liquid crystal display devices have different working modes, such as 6 / 8 bit code or wide and narrow viewing angle modes. For example, when the user wants to switch from the wide viewing angle mode to the narrow viewing angle mode when using the liquid crystal display device, or when the user wants to switch from the narrow viewing angle mode to the wide viewing angle mode when using the liquid crystal display device, it is necessary to switch off the computer and restart the liquid crystal display device. Th...
