[0004] The main purpose of the present invention is to propose a wide-narrow viewing angle switching module and a liquid crystal display device, aiming at solving the problem that the existing technology cannot take both wide viewing angle and narrow viewing angle into account when the self-refresh signal (Panel Self Refresh, PSR) function is turned on to switch between wide and narrow viewing angles. The quality requirements of the viewing angle and the switching time of wide and narrow viewing angles

Abstract
The invention discloses a wide-narrow perspective switch module and a liquid crystal display device. The wide-narrow perspective switch module comprises a connecting device, a signal processor and a time sequence controller; a display interface signal and a power source signal are output to the time sequence controller through the connecting device; a wide-narrow perspective control signal is output to the signal processor through the connecting device; the signal processor receives the wide-narrow perspective control signal, a wide perspective code or a narrow perspective code is chosen according to the wide-narrow perspective control signal, and the chosen wide perspective code or narrow perspective code is output to the time sequence controller; the time sequence controller receives the wide perspective code or the narrow perspective code, and outputs the wide perspective code or the narrow perspective code to a display panel. According to the wide-narrow perspective switch module and the liquid crystal display device, the definition of the wide-narrow perspective and the wide-narrow perspective switch time are both taken into account, and the problem is avoided that after a PSR signal of the time sequence controller is opened, the power-off restart time and switch time of the time sequence controller are too long during wide-narrow perspective switch.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a wide and narrow viewing angle switching module 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 display or wide and narrow viewing angle display 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 r...
