Abstract
The utility model discloses an LCD automobile instrument, which comprises an LCD display screen, a PCB and an LED lamp. The LCD automobile instrument is characterized in that the LED lamp is arranged on the PCB, and an optical filter with the size identical to that of the LCD display screen is arranged above the LED lamp. By utilizing the above structure, the LCD automobile instrument has the following advantages of 1, guaranteeing stability of LCD display and brightness uniformity of LED lamp and leading the LCD display screen to be softer and clearer in display, and 2, reducing product failure caused by uneven lighting of LCD by uniformizing backlight lamps of the LCD display screen.
Description
Relate to the field
The utility model relates to the auto meter field, particularly a kind of LCD auto meter.
Background technology
Progress along with epoch and science and technology, people require more and more higher to the fashion and the class of automobile electronics, the use of LCD in automobile electronics such as modern combination instrument is more and more frequent, but show for present existing LCD, because LCD is made up of a plurality of LED lamps the bottom, and the light source of LCD is to spread to the outside from the center of LED lamp, formed light from the center by force to outside weak progressive formation, cause the LCD backlight illumination inhomogeneous, thereby cause the stability of product to be protected.
Guarantee the stability of LCD demonstration and the homogeneity of LED lamp brightness, 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 LCD auto meter is provided, and guarantees the stability that LCD shows and the homogeneity of LED lamp brightness to reach, and reduces because the purpose of the product failure that the LCD non-uniform light causes.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of LCD auto meter, comprise LCD display, pcb board, LED lamp, it is characterized in that: described LED lamp is arranged on the pcb board, the top of LED lamp is provided with and LCD display filter of the same size, thereby by the light uniformization of filter with the LED lamp, has guaranteed the homogeneity of LED lamp brightness.
It is the center that described filter is provided with the corresponding position of LED lamp, and diameter circle is from big to small dispersed solid object, thus by solid object for the blocking of LED lamp brightness, reach purpose to LED lamp light uniformization.
The material of described filter is 20% transparent PC material, and solid object is 50% transparent printing opacity white paint, thereby better makes light flexibility, the uniformization of LED lamp.
A kind of LCD auto meter, owing to adopt said structure, this device 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 uniformization, reduced the product failure that causes because of the LCD non-uniform light to the LCD display backlight.
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 LCD auto meter of the utility model;
Fig. 2 is the scheme drawing of the solid object of a kind of LCD auto meter of the utility model;
In Fig. 1-2,1, LCD display; 2, pcb board; 3, LED lamp, 4 filters; 5, solid object.
The specific embodiment
Shown in Fig. 1-2, a kind of LCD auto meter, comprise LCD display 1, pcb board 2, LED lamp 3, it is characterized in that: described LED lamp 3 is arranged on the pcb board 2, the top of LED lamp 3 is provided with and LCD display 1 filter 4 of the same size, thereby, guaranteed the homogeneity of LED lamp 3 brightness by the light uniformization of filter 4 with LED lamp 3.
It is the center that described filter 4 is provided with LED lamp 3 corresponding positions, and diameter circle is from big to small dispersed solid object 5, thus by solid object 5 for the blocking of LED lamp 3 brightness, reach purpose to LED lamp 3 light uniformization.
The material of described filter 4 is 20% transparent PC material, and solid object 5 is 50% transparent printing opacity white paint, thereby better makes light flexibility, the uniformization of LED lamp 3.
It is backlight inhomogeneous that the utility model solves LCD display 1, owing to form by a plurality of LED lamps 3 bottom the LCD, and led light source is to spread to the outside from LED lamp 3 centers, formed light by force to outside weak progressive formation, causes the LCD backlight illumination inhomogeneous from the center.
The center-point that filter 4 is provided with solid object 5 is solid, blocks the high light of LED lamp 3, makes LED high light and the light that does not have pattern produce balance.Center-point then blocks with the large circle point of the center-point pattern to the dot gradual change of external point to the light of outside diffusion, and the center-point that makes LED is to the light of external point diffusion and do not have the light generation balance of pattern.LCD display 1 integral body backlight that makes is even.
Filter 4 adopts 20% transparent PC material, adds the solid object 5 of the transparent printing opacity white paint pattern of one deck 50% on filter 4.And the center of LED lamp 3 is aimed in the center of circle of pattern.
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.
