Abstract
The utility model relates to a backlit liquid crystal displayer of a computer oil pump, comprising a shell body, a liquid crystal display panel and a liquid crystal display connecting plate. The liquid-crystal display panel and the liquid-crystal display connecting plate are fixed to the shell body, the shell body is specifically and fixedly provided with a luminous element, and the light sent from the luminous element can be irradiated on the back part of the liquid-crystal display panel. Compared with the same kind of products, the liquid crystal displayer of a computer oil pump overcomes the defect that the reading number is indistinct because of the too strong light of the front part of the liquid-crystal display panel. Thereby, the backlit liquid crystal displayer of a computer oil pump with clear display is formed.
Description
The utility model relates to a kind of LCD, especially a kind of LCD of computer fuel charger special use.
At present, the use of computer fuel charger is very extensive.The LCD that is adopted on the existing computer fuel charger mainly is made of housing, LCD panel and liquid crystal display terminal block, and LCD panel and liquid crystal display terminal block are fixed on the housing.During use, the signal wire of computer is linked to each other with the liquid crystal display terminal block of display, the shows signal of computer output can make LCD panel demonstrate the data that record.In addition, for the ease of watch the reading on the LCD panel when light is dark, existing computer fuel charger LCD is provided with illuminating lamp in the place ahead of LCD panel.But the illuminating effect of the above-mentioned illuminating lamp that is positioned at LCD panel the place ahead is unsatisfactory, and the user is often reflected because of the display board front light and is difficult to see clearly reading on the display board too by force.Therefore, this existing computer fuel charger special liquid crystal display exists defective.
The purpose of this utility model is that the light structures to above-mentioned existing computer fuel charger LCD improves, and a kind of computer fuel charger LCD of clear display is provided.
The purpose of this utility model realizes in the following manner: be positioned at LCD panel the place ahead in the existing computer fuel charger LCD of cancellation, the LCD panel antetheca is imposed bright illuminating lamp, light can be shone in the light-emitting component at LCD panel back and be provided with in display.In the utility model, above-mentioned light can the irradiation in the light-emitting component at LCD panel back can be from likes such as vehement lamp or high brightness LEDs.By choosing the position being set or setting up reflecting part of this light-emitting component, can make light that light-emitting component sends directly or illuminate the back of LCD panel by reflection.When need make bright direct irradiation that light-emitting component sends in the back of LCD panel, light-emitting component can be arranged at the rear or the proceeds posterolateral of LCD panel, make light-emitting component directly relative with the back of LCD panel.And when illuminating the back of LCD panel indirectly, then can make light-emitting component directly relative with the back of LCD panel by the reflecting part of setting up (as reflective mirror).When using LCD of the present utility model, because the light that light-emitting component sends shines the back in LCD panel, when increasing LCD panel brightness, can not make the place ahead of LCD panel too bright, show that maintenance is clear thereby make.In addition, in order to adapt to the requirement of different user to display color, also can set up the color filter that the display board back is blocked near the back of LCD panel, the light that is radiated at the display board back is become coloured light.Simultaneously, also can set up reflex housing, to strengthen the directivity of light at the light-emitting component place.
Computer fuel charger LCD of the present utility model compared with the aforementioned existing similar products, because the light that light-emitting component sends shines the back in LCD panel, overcome because of liquid crystal display prelaminar part light causes the unsharp disadvantage of reading too by force, thereby constituted a kind of computer fuel charger backlight liquid crystal display of clear display.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of computer fuel charger backlight liquid crystal display among the embodiment.
Fig. 2 is the A-A cut-open view.
Fig. 3 is a B portion enlarged drawing.
Fig. 4 is a bulb power interface board circuit diagram.
Shown in Fig. 1～3, the computer fuel charger backlight liquid crystal display in the present embodiment has housing 1, LCD panel 2 and liquid crystal display terminal block 3, and LCD panel 2 and liquid crystal display terminal block 3 all are fixed on the housing 1.In the utility model, on housing, fixedly install luminance to some extent especially and can shine light-emitting component 4 in the 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 incandescent lamp.In addition, also between LCD panel 2 and light-emitting component 4, have additional color filter 7 in the present embodiment, to change the color of LCD panel back light.Simultaneously, also be provided with light reflex housing 6 at light-emitting component 4 places,
Be provided with cover plate 7 in LCD panel the place ahead.The purpose that light reflex housing 6 is set is the directivity that increases light, further guarantees illuminating effect.The purpose that cover plate 7 is set then is that the display interior structure is protected.
In the present embodiment, more perfect for making light structures, also in housing, be provided with bulb power interface board 8.The circuit of above-mentioned power interface plate promptly has solid-state relay U1 and hand switch K1 as shown in Figure 4, when computer is differentiating that oil gun is mentioned or during operation keyboard, makes light-emitting component L1, L2 get electric lighting by the control signal of the S end input of power interface plate; When putting down oil gun, the signal that computer provides will make lamp extinguish.If luminous for a long time, can open hand switch K1, directly power supply and light-emitting component are connected.
In addition, according to actual needs, the power interface plate 8 in the present embodiment also can be set, and light-emitting component and power supply are joined.
Present embodiment all is provided with the identical LCD panel of structure 2, liquid crystal display terminal block 3, light-emitting component 4, color filter 5, reflection shield 6, cover plate 7 and bulb power interface board 8 on the two sides, front and back of display, so that all can watch reading in the forward and backward side of display.
Claims (3)
1, a kind of computer fuel charger backlight liquid crystal display, have housing, LCD panel and liquid crystal display terminal block, LCD panel and liquid crystal display terminal block all are fixed on the housing, and it is characterized in that fixedly installing on housing to some extent, luminance can shine in the light-emitting component at LCD panel back.
2, LCD as claimed in claim 1 is characterized in that described light-emitting component is positioned at the rear of LCD panel, and is oppositely arranged with the back of LCD panel.
