Embodiment Construction
[0037] The preferred embodiments of the present invention are described in detail below with reference to the drawings.
[0038] See first figure 1 A schematic diagram showing the first structure of the operating voltage switching system of the liquid crystal panel according to the embodiment of the present invention, please also refer to figure 2 A schematic diagram of the signal difference variation of the frequency signal according to the embodiment of the present invention is shown.
[0039] The system is built in a liquid crystal panel of GIP structure, and the liquid crystal panel includes a plurality of liquid crystal components 23 and their liquid crystal control components. The liquid crystal component 23 is connected by a plurality of scanning signal lines in rows and a plurality of data signal lines in rows, and the data signal lines and scanning signal lines are respectively connected by more than one liquid crystal control component. To at least one source modu...

The invention discloses an operating voltage switching system of a liquid crystal panel and a switching method thereof. A time sequence controller of the panel acquires a liquid crystal initiation signal to generate a frequency signal, a frequency generator is a liquid crystal control module which acquires the frequency signal in order to control the liquid crystal panel, a basic signal offered by a voltage supplier is acquired and a first signal offered by the voltage supplier is transferred by a switcher in order to adjust the signal difference of the frequency signal. When a counter judgesthat the liquid crystal panel is initiated and meets a counting condition, the switcher is enabled to operate to transfer a second signal offered by the voltage supplier, and the frequency signal is adjusted to conform to the signal difference between the basic signal and the second signal.
Description
technical field [0001] The invention relates to a working power system of a liquid crystal panel, in particular to a working voltage switching system and a switching method of a liquid crystal panel capable of switching the working voltage. Background technique [0002] In the prior art, when the liquid crystal panel is working in a low temperature environment, the temperature of the liquid crystal component is often too low due to the excessively cold environment, which makes it impossible to quickly enter the working state when starting up, especially the current GIP (Gate in panel, built-in The panel with the gate circuit) is the most, because the panel with GIP structure will have insufficient signal power output capability in low temperature environment, and the LCD component will not work quickly and normally, resulting in delay, abnormality or stagnation of the screen within a few seconds after booting. Therefore, when manufacturers make LCD panels, they will consider...
