Abstract
The invention relates to a backlit liquid crystal displayer for a computer refueling machine. The backlit liquid crystal displayer comprises a shell and liquid crystal display boards and liquid crystal display wiring boards which are both fixed on the shell, and light-emitting elements are particularly and fixedly arranged on the shell, wherein light emitted by the light-emitting elements can irradiate the backs of sub liquid crystal display boards. Compared with existing similar products, according to the liquid crystal displayer for the computer refueling machine, the defects that a reading is unclear due to the fact that the light on the front portions of the liquid crystal display boards is too strong is overcome, and therefore the backlit liquid crystal displayer achieving clear display for the computer refueling machine is formed.
Description
Technical field
The present invention relates to a kind of liquid crystal display, especially a kind of Unexposured liquid crystal displayer of computer oil pump.
Background technology
At present, the use of computer fuel charger is the most quite varied.The liquid crystal display used on existing computer fuel charger is mainly made up of housing, LCD panel and liquid crystal display patch panel, and LCD panel and liquid crystal display patch panel are fixed on housing.During use, being connected with the liquid crystal display patch panel of display by the holding wire of computer, the display signal of computer output can make LCD panel demonstrate the data recorded.It addition, for the ease of watching the reading on LCD panel when dark, existing computer fuel charger liquid crystal display is provided with illuminating lamp in the front of LCD panel.But, the illuminating effect of the above-mentioned illuminating lamp being positioned at LCD panel front is unsatisfactory, and user often reflects that tired display panel front light is difficult to the reading seeing clearly on display panel too by force.Therefore, this existing computer fuel charger specialized LCD also exists defect.
Summary of the invention
It is an object of the invention to the light structures of above-mentioned existing computer fuel charger liquid crystal display is improved, it is provided that one shows computer fuel charger liquid crystal display clearly.
The purpose of the present invention is accomplished by: cancel LCD panel front, seat in existing computer fuel charger liquid crystal display, LCD panel antetheca imposes bright illuminating lamp, and arrange the light-emitting component that light can irradiate sub-LCD panel back in display.In the present invention, the above-mentioned light-emitting component that light can irradiate sub-LCD panel back can be the like such as electric filament lamp or high brightness LED.By choosing arranging position or setting up reflecting part of this light-emitting component, the light that light-emitting component can be made to be sent illuminates the back of LCD panel directly or by reflection.When the bright direct irradiation that light-emitting component need to be made to send is in the back of LCD panel, light-emitting component can be arranged rear or the rear flank side of sub-LCD panel, make light-emitting component the most relative with the back of LCD panel.And when between the reflecting part (such as illuminator) by setting up according to the back of bright LCD panel time, then light-emitting component can be made the most relative with the back of LCD panel.When using the liquid crystal display of the present invention, due to the back of the light LCD panel of irradiation that light-emitting component sends, while increasing LCD panel brightness, the front that will not make LCD panel is the brightest, so that display keeps clear.
It addition, in order to adapt to the different user requirement to display color, the color filter blocked at display panel back also can be set up near the back of LCD panel, makes the light being radiated at display panel back become colored light.Meanwhile, reflector can also be set up at light-emitting component, to strengthen the directivity of light.
The computer fuel charger liquid crystal display of the present invention is compared with the aforementioned existing similar products, back due to the light LCD panel of irradiation that light-emitting component sends, overcome and cause the unsharp disadvantage of reading because LCD panel front portion light is too strong, thus constitute one and show Unexposured liquid crystal displayer of computer oil pump clearly.

Detailed description of the invention
Present disclosure is further described with the following Examples, but present disclosure is not limited only in embodiment involved content.
As shown in Fig. 1 ~ 2, the Unexposured liquid crystal displayer of computer oil pump in the present embodiment has housing 1, LCD panel 2 and liquid crystal display patch panel 3, LCD panel 2 and liquid crystal display patch panel 3 and is both secured on housing 1.In the present invention, on housing, it is fixedly installed luminance especially can irradiate the light-emitting component 4 at sub-LCD panel back.Above-mentioned light-emitting component 4 in the present embodiment is positioned at the rear of LCD panel 2, and is oppositely arranged with the back of LCD panel 2, and this light-emitting component 4 is served as by electric filament lamp.It addition, the present embodiment also has additional between LCD panel 2 and light-emitting component 4 color filter 7, to change the color of LCD panel back light.Meanwhile, at light-emitting component 4, also it is provided with lamplight reflecting cover 6, is provided with cover plate 7 in LCD panel front.The purpose arranging lamplight reflecting cover 6 is to increase the directivity of light, further ensures that illuminating effect.The purpose arranging cover plate 7 is then to protect display interior structure.
In the present embodiment, for making light structures more sophisticated, in housing, also it is provided with bulb power interface board 8.The circuit of above-mentioned power interface plate is as drawn shown in 3, i.e. there is solid-state relay U 1 and hand switch K 1, when computer is mentioned in differentiation to oil gun or operated keyboard, the S end of power interface plate the control signal inputted makes light-emitting component L 1, L 2 obtain electric lighting；When putting down oil gun, the signal that computer is given will make lamp extinguish.To long-term luminous, hand switch K 1 can be opened, directly power supply is connected with light-emitting component, it addition, according to actual needs, it is possible to the power interface plate 8 being not provided with in the present embodiment, and the most directly make light-emitting component connect with power supply.
The present embodiment two sides before and after display is provided with the identical LCD panel of structure 2, liquid crystal display patch panel 3, light-emitting component 4, color filter 5, reflection shield 6, cover plate 7 and bulb power interface board 8, in order to all can watch reading in the forward and backward side of display.
