Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0062] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0063] figure 1 It is a structural diagram of a mode selection module in the prior art, including a 12-bit shift register composed of 12 D flip-flops (DFF) and 6 latches (Latch) for latching serial input signals. The mode signal only involves the first 6 DFFs of the 12bit shift register, and the r...

Abstract

The invention discloses a serial-to-parallel conversion circuit and a driving method thereof, a mode latch circuit and a display device. The circuit comprises a sampling pulse signal generation module and a plurality of signal latch modules, and the sampling pulse signal generation module is provided with a plurality of output ends connected with the control ends of the signal latch modules in a one-to-one correspondence manner; the sampling pulse signal generation module is used for generating a plurality of sampling pulse signals under the control of a clock signal and an enable signal and respectively outputting the sampling pulse signals to the control ends of the corresponding signal latch modules; and the signal latching module is used for latching and outputting the serial input signal received by the input end of the signal latching module under the control of the reset signal and the corresponding sampling pulse signal. The serial-to-parallel conversion circuit has enough time sequence redundancy and is suitable for high-frequency signal transmission stability.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to a serial-to-parallel conversion circuit, a driving method thereof, and a display device. Background technique [0002] In the drive circuits of some display devices, in the prior art, the latch of the mode signal is realized by a shift register, which requires an additional counter to control the latch of the mode signal, and the phenomenon of latch misalignment is prone to occur under high-frequency operation, resulting in The overall function of the circuit fails, and the circuit stability is not enough. Contents of the invention [0003] In view of the above defects or deficiencies in the prior art, it is desired to provide a serial-to-parallel conversion circuit, a driving method thereof, a mode latch circuit, and a display device. [0004] In a first aspect, the present invention provides a serial-to-parallel conversion circuit, comprising: a sampli...
