Abstract
The utility model relates to the technical field of computer peripherals, in particular to a backlight module of a liquid crystal display (LCD) with brightness adjustable. The backlight module of the LCD with brightness adjustable comprises a light-emitting module, a ray sensor and a brightness controller. The brightness controller is connected with the light-emitting module and the ray sensor. According to the backlight module of the LCD with brightness adjustable, the light-emitting module and the ray sensor are arranged so as to enable the light-emitting brightness of an LCD to be adjusted to the best brightness according to environmental light and be beneficial for protecting eyes.
Description
Technical field
The utility model relates to computer peripheral equipment technical field, specifically, relates to the adjustable LCD screen backlight module of a kind of brightness.
Background technology
Fast development along with electronic product, the technology of LCDs is more and more higher, display screen changes liquid crystal into from traditional CRT gradually, because LCDs itself is not luminous, but passive luminous, so need backlight that light source is provided, manual transfer is mostly adopted in the brightness of present LCDs, generally all keeping dispatches from the factory regulates the brightness of setting, and can not change because of the brightness of environment for use; Therefore a lot of users have ignored the adjusting to the brightness of LCDs, think that the screen of knowing of seeing gets final product, and is unfavorable for the health of eyes very much.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of brightness adjustable LCD screen backlight module, this LCD screen backlight module can come by the perception ambient brightness luminosity of adjustable liquid crystal display display screen, thereby reach better visual effect, be conducive to eye health.
For achieving the above object, the technical solution adopted in the utility model is:
The LCD screen backlight module that a kind of brightness is adjustable comprises illuminating module, light sensor and brightness controller, and described brightness controller is connected with light sensor with illuminating module respectively.
Further, described illuminating module is the LED module, and described LED module comprises the LED luminescence unit.
Further, described LED luminescence unit comprises red LED, blue led and green LED, and described LED module also comprises the light modulator, and the light adjuster is connected with the LED luminescence unit.
Again further, the number ratio of the red LED of each LED unit, blue led, green LED is: 1:1:1.
Further, described backlight module is the side-light backlight module.
The beneficial effects of the utility model are: the utility model so that the luminosity of LCDs can be adjusted to better brightness according to the light of environment, is conducive to protect eyes by light sensor and brightness controller are set.
Description of drawings
Fig. 1 is composition schematic diagram of the present utility model.
Reference numeral is:
1---LED module 2---LED luminescence unit
3---light modulator 4---light sensor
5---brightness controller.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Embodiment: referring to accompanying drawing 1.
The LCD screen backlight module that a kind of brightness is adjustable comprises illuminating module, light sensor 4 and brightness controller 5, and described brightness controller 5 is connected with light sensor with illuminating module respectively and is connected.
The utility model comes the light luminance of induced environment by light sensor 4 is set in backlight module, brightness controller 5 is set simultaneously according to the luminous intensity of the light intensity control illuminating module of environment, thereby so that LCDs reaches one good illumination effect, so that LCDs has a preferably visual effect, be conducive to human eye health.
Further, described illuminating module is LED module 1, and described LED module 1 comprises LED luminescence unit 2.
Illuminating module is arranged to LED module 1, and LED lamp source has can be energy-conservation, and therefore the characteristics that the life-span is long are saved the use energy of display screen and increased the service life.
Further, described LED luminescence unit 2 comprises red LED, blue led and green LED, and described LED module 1 also comprises light modulator 3, and light modulator 3 is connected with LED luminescence unit 2.
By light modulator 3 and three-color LED light are set, so that LED luminescence unit 2 can come the glow color of adjustable liquid crystal display display screen as required, to satisfy the requirement of different human eyes.
Again further, the number ratio of the red LED of each LED unit, blue led, green LED is: 1:1:1.
Be that 1:1:1 is the simplest with red LED, blue led, green LED Set scale, and realize easily the allotment of light.
Further, described backlight module is the side-light backlight module.
Adopt the side-light backlight module, can be conducive to reduce the thickness of display screen, help with display screen do thinner, occupy little space.
The utility model has been done to explain, and those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from essence and the scope of technical solutions of the utility model.
