Abstract

The utility model relates to a luminous structure for a liquid crystal display, comprising an LCD liquid crystal display panel. A light-conducting panel and a diffusion panel are arranged below the liquid crystal display panel, and the side of the light-conducting panel is provided with the light source of a lighting diode. A luminous slice is arranged on the bottom surface of the liquid crystal display panel and has the lighting effect. Under the condition without light of a night, etc., the utility model is convenient to for a user to see clearly the liquid crystal display panel. Because of the luminous slice, the utility model provides other selection for the user except the light source to reduce the power which is consumed by the light source of the lighting diode, etc. So the utility model can save electrical source, and the battery can be often not replaced.

Description

LCD noctilucence structure

The utility model relates to a kind of LCD (LCD) noctilucence structure, is meant a kind of energy of saving especially, does not need often to change the LCD noctilucence structure of battery.

LCD (LCD) has been widely used on the products such as pager, mobile phone, generally when using night, need be combined with light sources such as light emitting diode, so that see content shown on the LCD panel of LCD clearly, but the use of light sources such as light emitting diode rather consumes electric power, as frequent use, cause the waste of the energy unavoidably.

Order of the present utility model provides a kind ofly both can see LCD panel clearly under the light unfavorable condition at night, can save the LCD noctilucence structure of the energy again.

The utility model is achieved in that the LCD panel that includes a LCD, this LCD panel is connected with a circuit board with line row, the LCD panel below is provided with light guide plate, diffusion sheet, the light guide plate side is provided with the light source of light emitting diode, it is characterized in that: the LCD panel bottom surface is provided with a luminous plate, and this luminous plate has luminous effect.

This LCD noctilucence structure can be installed on pager or the mobile phone.

The utility model includes the LCD panel of a LCD, this LCD panel is connected with a circuit board with line row, the LCD panel below is provided with light guide plate, diffusion sheet, the light guide plate side is provided with the light source of light emitting diode, the LCD panel bottom surface is provided with a luminous plate, and this luminous plate has luminous effect.Under light unfavorable conditions such as night, can be convenient to the user and see LCD panel clearly, nationality is by the setting of luminous plate, can provide the user to use the outer another kind of light source luminescent to select, with electric power that light source was consumed such as minimizing light emitting diodes,, need often to change battery to save power supply.

Fig. 1 is the three-dimensional combination figure of embodiment of the present utility model;

Fig. 2 is the three-dimensional exploded view of embodiment of the present utility model;

Fig. 3 is the partial sectional view of embodiment of the present utility model;

Fig. 4 is the stereographic map that is applied to pager of embodiment of the present utility model.

Consult Fig. 1～Fig. 3, the utility model includes the LCD panel 10 of a LCD, this LCD panel 10 is connected with a circuit board 12 with line row 11, LCD panel 10 belows are provided with the light guide plate 13 of suitable thickness, this light guide plate 13 is fixed on the circuit board 12, light guide plate 13 end faces are combined with a diffusion sheet 14, light guide plate 13 both sides are provided with light sources 15 such as light emitting diode, when light source 15 is luminous, light can be via the scattering principle of light guide plate 13, and make whole zone luminous by diffusion sheet 14, so that the user under night light unfavorable condition, still can see shown content on the LCD panel 10 of LCD clearly.Same as the prior art because of above-mentioned LCD structure, non-the utility model patent protection category is so no longer given unnecessary details.

The utility model mainly is by LCD panel 10 bottom surfaces, be to be provided with a luminous plate 16 between LCD panel 10 and the diffusion sheet 14, this luminous plate 16 of being located at LCD panel 10 bottom surfaces can have luminous effect, therefore, under light unfavorable conditions such as night, can be convenient to the user and see content shown on the LCD panel 10 clearly.Because the setting of luminous plate 16, can provide the user to use the luminous outer another kinds of light source 15 to select, so nationality is by the use of luminous plate 16, can reduces the electric power that light source 15 such as light emitting diode is consumed, reaching the function of saving the energy, and need often to change battery.

Consult Fig. 4, the utility model can be installed on the products such as pager 20, mobile phone.
