Abstract
The utility model discloses a novel liquid crystal display (LCD) screen, which comprises an LCD screen, a light guide bracket, a PCB and LED lamps. The novel LCD screen is characterized in that the LED lamps are arranged on the PCB inside the light guide bracket; rectangle light guide plates are arranged among the LED lamps. By adopting the structure, the display screen has the advantages of (1) guaranteeing the stability of LCD and the uniformity of the illumination of the LED lamps so that the display of the LCD screen is softer and clearer; (2) reducing the failure of the product caused by the nonuniform LCD luminescence by homogenizing the backlight of the LCD screen; (3) improving the beauty degree of the whole LCD screen by replacing the original point light source with the surface light source; and (4) reducing the amount of the used LED lamps and saving the production cost.
Description
Technical field
The utility model relates to the automobile instrument field, particularly a kind of novel LCD LCDs.
Background technology
Automobile combination meter is an important safety member in automobile, and it is the main parts that the driver obtains motoring condition information.At present, along with rapid development of automobile industry, the function of domestic automobile inside gadget and outward appearance are also in continuous innovation.The consumer also outward appearance of more concern automotive upholstery and function when purchasing car.And automobile main frame maker can not be ignored the moulded of combination instrument in research and development car load process, also show that by the LCD LCDs profile of LCD LCDs and content displayed will receive much attention so for some important informations on the combination instrument.Show for present existing LCD, because LCD bottom is made up of a plurality of LED lamps, and led light source is to spread to the outside from LED lamp center, formed light is the gradual change a little less than outside by force from the center, cause the LCD backlight illumination inhomogeneous, thereby cause the stability of product to be protected.
Realize the stability that LCD shows, guarantee the homogeneity of LED lamp brightness, improve the aesthetic measure of LCD LCDs, reduce because the product failure that the LCD non-uniform light causes is the problem that prior art need solve.
The utility model content
Technical problem to be solved in the utility model is, a kind of novel LCD LCDs is provided, comprise LCD display, leaded light support, pcb board, LED lamp, it is characterized in that: described LED lamp is arranged on and is positioned at leaded light support inboard on the pcb board, be provided with the light guide plate of rectangle between the LED lamp, thereby the total reflection by light guide plate of the light of LED lamp is delivered on the LCD display, reaches the backlight homogenising of LCD display, the purpose of flexibility.
Described leaded light support is " it " word structure, thereby make position between the LED lamp greater than the length of LCD display, can make the length of light guide plate consistent with the length of LCD display, reach the effect of better total reflection, and utilize the part in the middle of the light guide plate to block the LED lamp, avoid the light direct irradiation of LED lamp on LCD display, to cause the LCD display background light inhomogeneous.
Described leaded light support is welded on the pcb board, thereby makes that whole LCD LCDs is more firm.
Described light guide plate is a makrolon material.
A kind of novel LCD LCDs, owing to adopt said structure, this display screen has the following advantages: 1, guarantee the stability that LCD shows and the homogeneity of LED lamp brightness, make that the demonstration of LCD display is softer, clear; 2, by homogenising, reduced the product failure that causes because of the LCD non-uniform light to the LCD display backlight; 3, by replacing original pointolite, improve the aesthetics of whole LCD LCDs with area source; 4 reduce the number that the LED lamp uses, and save production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of a kind of novel LCD LCDs of the utility model;
In Fig. 1,1, LCD display; 2, leaded light support; 3, pcb board; 4, light guide plate; 5, LED lamp.
Embodiment
As shown in Figure 1, a kind of novel LCD LCDs, comprise LCD display 1, leaded light support 2, pcb board 3, LED lamp 5, it is characterized in that: described LED lamp 5 is arranged on and is positioned at leaded light support 2 inboards on the pcb board 3, be provided with the light guide plate 4 of rectangle between the LED lamp 5, thereby the total reflection by light guide plate 4 of the light of LED lamp 5 is delivered on the LCD display 1, reaches the backlight homogenising of LCD display 1, the purpose of flexibility.
Described leaded light support 2 is " it " word structure, thereby make position between the LED lamp 5 greater than the length of LCD display 1, can make the length of light guide plate 4 consistent with the length of LCD display 1, reach the effect of better total reflection, and utilize the part in the middle of the light guide plate 4 to block LED lamp 5, avoid the light direct irradiation of LED lamp 5 on LCD display 1, to cause LCD display 1 background light inhomogeneous.
Described leaded light support 2 is welded on the pcb board 3, thereby makes that whole LCD LCDs is more firm.
Described light guide plate 4 is a makrolon material.
Have the leaded light support to be used for supporting LCD under the LCD of common combination instrument and place the LCD backlight, the backlight of common LCD is placed under the LCD.But, for light guide plate LCD backing structure of the present utility model, at first it with LED lamp 5 than common lacking, secondly since its backlight be mapped to from the side on the light guide plate 4, be refracted on the LCD display 1 by light guide plate 4 again, make the backlight more even of LCD display 1.
Utilize total reflection principle that the light of LED lamp 5 is reflexed on the LCD display 1 by light guide plate 4, replace present pointolite, realize the flexibility and the homogenising of LCD display 1 background light with area source.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
