Description

A kind of LVDS turns MIPI output device

Technical field

The utility model relates to liquid crystal display field of display technology, especially a kind of LVDS turns MIPI output device.

Background technique

Existing liquid crystal display mainly passes through MIPI interface and is communicated with mainboard, however since industry control class mainboard updates It is relatively slow, LVDS interface signal is only supported mostly, there is a problem of that existing industrial control mainboard and liquid crystal display are incompatible, it is therefore necessary to A kind of device is invented to solve the above problems.

Utility model content

The utility model is intended to solve at least some of the technical problems in related technologies.For this purpose, this reality With a novel purpose be to provide it is a kind of by only support LVDS interface industrial control mainboard and only support MIPI interface liquid crystal display A kind of matched LVDS turns MIPI output device.

The technical scheme adopted by the utility model is

A kind of LVDS turns MIPI output device, comprising: LVDS signal input port, LVDS turn MIPI module, MIPI signal Output port, the output end of the LVDS signal input port connect the input terminal that the LVDS turns MIPI module, the LVDS The output end for turning MIPI module connects the input terminal of the MIPI signal output port.

Further, it includes LVDS conversion chip and LVDS conversion chip power supply circuit, institute that the LVDS, which turns MIPI module, The output end for stating LVDS conversion chip power supply circuit connects the input terminal of the LVDS conversion chip, the LVDS conversion chip Input terminal connects the output end of the LVDS signal input port, and the output end of the LVDS conversion chip connects the MIPI letter The input terminal of number output port.

Further, the LVDS conversion chip is 64 chip of LT9819L_QFN.

Further, the LVDS conversion chip power supply circuit includes TD6810 chip.

The beneficial effects of the utility model are: the utility model turns what MIPI module exported mainboard by the way that LVDS is arranged LVDS signal is converted into MIPI signal and exports to overcome the existing industrial control mainboard having to liquid crystal display and liquid crystal display is incompatible asks Topic, it is easy to use, it is low in cost.

Detailed description of the invention

Fig. 1 is the structure principle chart that a kind of LVDS of the utility model turns one specific embodiment of MIPI output device；

Fig. 2 is the structure principle chart that a kind of LVDS of the utility model turns MIPI output device still another embodiment；

Fig. 3 is the circuit diagram that a kind of LVDS of the utility model turns MIPI output device still another embodiment.

Specific embodiment

It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.

As shown in Figure 1, Fig. 1 shows the structure principle chart that a kind of LVDS of the utility model turns MIPI output device, including LVDS signal input port, LVDS turn MIPI module, MIPI signal output port, the output end of the LVDS signal input port The input terminal that the LVDS turns MIPI module is connected, the output end that the LVDS turns MIPI module connects the MIPI signal output The input terminal of port.

LVDS signal input port is connect with mainboard, is received the vision signal that mainboard is sent, is turned MIPI module by LVDS LVDS signal is converted into MIPI signal, MIPI signal output port is connect with liquid crystal display, is overcome by the utility model existing Some mainboards and the unmatched problem in liquid crystal display port, it is practical and convenient, low in cost.

Shown in Fig. 2, Fig. 2 be a kind of LVDS of the utility model turn MIPI output device still another embodiment structure it is former Reason figure, it includes LVDS conversion chip and LVDS conversion chip power supply circuit that wherein LVDS, which turns MIPI module, and the LVDS converts core The output end of piece power supply circuit connects the input terminal of the LVDS conversion chip, and the input terminal of the LVDS conversion chip connects institute The output end of LVDS signal input port is stated, the output end of the LVDS conversion chip connects the MIPI signal output port Input terminal.

LVDS conversion chip power supply circuit is used to power for LVDS conversion chip, and LVDS conversion chip is for specifically executing letter Number conversion.

As shown in figure 3, Fig. 3 is the circuit original that a kind of LVDS of the utility model turns MIPI output device still another embodiment Reason figure, 1 is LVDS signal input port, and 2 be LVDS conversion chip and its peripheral circuit, and 3 be MIPI signal output port, and 4 are LVDS conversion chip power supply circuit, wherein LVDS conversion chip is 64 chip of LT9819L_QFN, LVDS conversion chip power supply electricity Road includes TD6810 chip.

The utility model is small in size, both may be mounted on liquid crystal display or may be mounted in industry control machine host, user Just, while the LVDS interface of industrial personal computer and the MIPI interface of liquid crystal display are remained, without changing existing structure, with good Compatibility.

It is to be illustrated to the preferable implementation of the utility model, but the invention is not limited to the reality above Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
