Abstract
The utility model provides an intelligent fuel gas meter with a backlight liquid crystal display. The intelligent fuel gas meter is characterized in that a bottom surface of the liquid crystal display of the intelligent fuel gas meter is provided with a backlight plate, and the backlight plate is internally provided with luminotrons. The intelligent fuel gas meter provided by the utility model has the advantages that the structure is simple, the use is convenient, the contents of the liquid crystal display can be seen clearly, the intelligent fuel gas meter is free from the influence of ray, and the fact that display contents can not be seen clearly because of wrong visual angle is avoided.
Description
Technical field
The utility model belongs to the gas meter, flow meter field, specifically is a kind of intelligent gas meter that has back-light liquid crystal display screen.
Background technology
Multiple intelligent gas meter is checked data in the table for ease like IC-card table etc., has all used LCDs, and general LCDs is a gray background, under well-lighted condition, can know and see displaying contents.Along with attractive in appearanceization, the integration of house decoration, a lot of gas meter, flow meters are encapsulated in high cube container or the cabinet, can't see the liquid crystal display content clearly, and have the LCDs of backlight function just can address this problem.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of intelligent gas meter that has back-light liquid crystal display screen.
A kind of intelligent gas meter that has back-light liquid crystal display screen is characterized in that being provided with backlight in the bottom surface of the LCDs of intelligent gas meter, is provided with luminotron in the said backlight.
The intelligent gas meter that has back-light liquid crystal display screen of the utility model, simple in structure, easy to use, can clearly see the liquid crystal display content, not influenced by light, also not can because of the visual angle not to not seeing Chu's displaying contents.
Description of drawings
Fig. 1 is the vertical view of the utility model;
Fig. 2 is the front elevation of the utility model;
Among the figure, 1-LCDs; 2-backlight.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of intelligent gas meter that has back-light liquid crystal display screen of the utility model is provided with backlight 2 in the bottom surface of the LCDs 1 of intelligent gas meter, is provided with luminotron in the backlight 2.
During work, backlight connects single-chip microcomputer control port and ground wire, need check the liquid crystal display content, Single-chip Controlling port output high level, and luminotron is lighted in the backlight, and the liquid crystal display displaying contents is more clear under setting off backlight; Check to finish, Single-chip Controlling port output low level, luminotron extinguishes in the backlight.Backlight also can Chang Liang, but power consumption is bigger like this.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
