Fig. 2 represents the light path schematic diagram one of the backlight of liquid crystal indicator in the utility model embodiment;
Fig. 3 represents the light path schematic diagram two of the backlight of liquid crystal indicator in the utility model embodiment;
Fig. 4 represents the light path schematic diagram three of the backlight of liquid crystal indicator in the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 2, the utility model provides a kind of liquid crystal indicator, and it comprises display panel 10, and display panel 10 comprises viewing area 11 and is positioned at the non-display area 12 of 11 peripheries, viewing area.Also being included as viewing area 11 provides the backlight of light.
Described backlight is LED-backlit source, and the LED lamp bar 20 of use comprises multiple LED unit 1 and 2.For an adjacent LED unit 1 and the 2nd LED unit 2, the intersection points B on the border, light area that the one LED unit 1 is adjacent with the 2nd LED unit 2 is positioned at the non-display area 12 of 11 peripheries, viewing area, and be not positioned at viewing area 11, thereby can effectively solve the problem that occurs firefly phenomenon in viewing area 11, improve display quality.
It should be noted that, the border, light area of a LED unit 1 and the 2nd LED unit 2 refers to: the light area 100 of a LED unit 1 and the 2nd LED unit 2 has certain subtended angle, and two rays that this subtended angle is corresponding are border, light area.
The intersection points B on the border, light area that the one LED unit 1 is adjacent with the 2nd LED unit 2 is positioned at non-display area 11 and comprises following two kinds of situations:
Intersection points B is positioned on the side (comprising the side adjacent with viewing area 11 and the side away from viewing area 11) of non-display area 12; With
Intersection points B is positioned at the region of the side encirclement of non-display area 12.
In order to meet the requirement of liquid crystal indicator 10 to brightness, design LED lamp bar 20 comprises the LED unit of at least two kinds of package dimensions, and an adjacent LED unit 1 is different with the package dimension of the 2nd LED unit 2, as the package dimension of a LED unit 1 is greater than the package dimension of the 2nd LED unit 2, shown in Figure 2.In the case of the size of LED lamp bar 20 and total lumen certain, by adopting the LED unit of at least two kinds of package dimensions, can increase the number of LED unit, reduce the spacing between LED unit, make the more close LED of intersection points B unit, away from viewing area 11, in the time that intersection points B is positioned at non-display area 12, can effectively solve the problem that occurs firefly phenomenon in viewing area 11.Because the package dimension of a LED unit 1 is greater than the package dimension of the 2nd LED unit 2, compared to all adopting a large-sized LED unit 1, improve radiating effect.Meanwhile, for adopting the producer of LED product, the use of different kinds material, the slow-witted material of avoidable stock, reduces the cost that demand material is purchased, and is conducive to improve the market competitiveness of enterprise.
In a concrete embodiment, LED lamp articles 20 comprises a LED unit 1 and the 2nd LED unit 2 of two kinds of package dimensions, and a LED unit 1 and 2 intervals, the 2nd LED unit arrange, as shown in Figure 2, and to simplify the piece technique of LED lamp bar 20.
Further, the intersection points B that the border, light area that the one LED unit 1 is adjacent with the 2nd LED unit 2 can also be set is positioned on the side that non-display area 12 is adjacent with viewing area 11, make that the light of a LED unit 1 and the 2nd LED unit 2 is more abundant must offer viewing area 11, increase the utilization factor to light.
Certainly, LED lamp bar 20 also can comprise more than three kinds or three kinds package dimension LED unit.Concrete, as shown in Figure 3 and Figure 4, when LED lamp bar 20 comprises the LED unit 1,2 and 3 of three kinds of package dimensions, and when the package dimension of adjacent LED unit is different, in the case of the size of LED lamp bar 20 and total lumen certain, further increased the number of LED unit, reduced the spacing between LED unit, make intersection points B be positioned at non-display area 12, also can effectively solve the problem that occurs firefly phenomenon in viewing area 11.
In the utility model embodiment, the brightness that designs all LED unit is identical, and LED number of unit is more, and the brightness of whole LED lamp bar 20 is also higher, increases display brightness.
Preferably, an adjacent LED unit and the 2nd LED unit spaced set can also be set, make the heat radiation equalization more of LED lamp bar 20, improve radiating effect.
In technique scheme, the lamp bar that the backlight of liquid crystal indicator uses comprises multiple LED unit, by being set, the intersection point on the close border, light area in an adjacent LED unit and the 2nd LED unit is positioned at the non-display area of periphery, viewing area, and be not positioned at viewing area, thereby can effectively solve the problem that occurs firefly phenomenon in viewing area, improve display quality.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
