Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, Fig. 1 is the flow chart of television set illuminated by surface light source method in the first embodiment of the invention, and the television set illuminated by surface light source method that this embodiment mentions comprises:
Step S10, television set receives the light illumination mode start signal, gets into light illumination mode;
In the present embodiment, special-purpose light illumination mode can be set on remote controller open button, the remote signal of opening through remote controller output light illumination mode is to television set; Or special-purpose light illumination mode unlatching button is set on television receiver body, open light illumination mode through pushing button; Also the control that light illumination mode is opened can be set on the main menu that television screen shows, carry out control through the button on remote controller or the television receiver body and select, open light illumination mode.Wherein, light illumination mode comprises desk lamp pattern and/or night-light pattern, when the user need read books and periodicals or study, can select the desk lamp pattern; When user's rest at night, can select the night-light pattern.
Step S20, television set is opened the LED-backlit area source of display screen;
Present embodiment is after getting into light illumination mode, and the LED-backlit area source of television set control display screen is opened, and makes the screen of entire display screen luminous, as lighting source.Because television screen is LCDs, light is when passing liquid crystal molecule, and LCD screen can not refresh and light situation such as beat occurs with the signal frame screen; The LED-backlit that adopts television screen is as the illuminated area light source, and illumination is more even, even under the situation that increases light source power; Brightness is also very soft; Can not stimulate eyes, and can guarantee good lighting effect, satisfy the demand of user illumination brightness.
Step S30, television set receives the light illumination mode shutdown signal, withdraws from light illumination mode.
Present embodiment can be provided with special-purpose light illumination mode and close button on remote controller, the remote signal of closing through remote controller output light illumination mode is to television set; Or special-purpose light illumination mode is set on television receiver body closes button, close light illumination mode through pushing button; Control that also can the display lighting pattern is closed on television screen carries out control through the button on remote controller or the television receiver body and selects, and closes light illumination mode.
As shown in Figure 2, Fig. 2 is the flow chart of television set illuminated by surface light source method in the second embodiment of the invention, comprises before the step S20:
Step S40, television set display lighting parameter is provided with the interface, accepts the typing of lighting parameter.
Present embodiment can be when getting into light illumination mode first; Or when the user starts light illumination mode at every turn; Or the lighting parameter of selecting according to the user is provided with button or menu control; The display lighting parameter is provided with the interface, and the lighting parameter that the user is provided with is kept in the television memory LED-backlit area source of the lighting parameter adjusting display screen that confession television set basis is preset.Wherein, lighting parameter can comprise luminance parameter, and the user is big or small according to the preset brightness of comfort level of self eye.To the desk lamp pattern, lighting parameter also can comprise bright lamp duration, for example, continuous bright lamp is set withdraws from light illumination mode after 1 hour automatically, extinguishes the LED-backlit area source of display screen, to play the effect of reminding the user regularly to have a rest; Forget the wasting of resources of closing the desk lamp pattern and causing when simultaneously, the setting of bright lamp duration also can avoid the user to go out.In addition; If the preset lighting parameter of user, or do not design lighting parameter in the television set the relevant control in interface is set, television set can be regulated the LED-backlit area source of display screen according to the default parameters that dispatches from the factory; Default value can be designed to classical brightness; For example research and analyse the parameter value that the back is selected, can effectively protect study reader's eyesight, prevent the generation of myopia or ophthalmology disease according to the ophthalmologist, oculist.
As shown in Figure 3, Fig. 3 is the flow chart of steps of desk lamp pattern in the television set illuminated by surface light source method of third embodiment of the invention, and step S20 specifically comprises:
Step S211, television set according to the lighting parameter of preset desk lamp pattern, regulate the brightness of LED-backlit area source after getting into the desk lamp pattern.
Present embodiment is to the desk lamp pattern; After the user opened the desk lamp pattern, the LED-backlit area source brightened, and brightness reaches preset luminance parameter; This luminance parameter is preset according to the level of comfort of self eye for the user, and this design makes intelligent TV set hommization more.In addition; If the preset lighting parameter of user, or do not design lighting parameter in the television set the relevant control in interface is set, television set can be regulated the LED-backlit area source of display screen according to the default parameters that dispatches from the factory; Default value can be designed to classical brightness; For example research and analyse the parameter value that the back is selected, can effectively protect study reader's eyesight, prevent the generation of myopia or ophthalmology disease according to the ophthalmologist, oculist.
As shown in Figure 4, Fig. 4 is the flow chart of steps of night-light pattern in the television set illuminated by surface light source method of fourth embodiment of the invention first embodiment, and step S20 specifically comprises:
Step S221, television set are after getting into the night-light pattern, and control LED-backlit area source gets into the blank screen holding state;
In the present embodiment, the user for night WA can adopt television set LED-backlit area source to throw light on, can before sleeping prerequisite, open the night-light pattern, this moment, the LED-backlit area source was not directly lighted, but got into the blank screen holding state.
Step S222, television set receives the night-light triggering signal, and the brightness of control LED-backlit area source increases to acquiescence brightness gradually by blank screen.
In the present embodiment; When user's WA at night has been opened the night-light trigger switch, the triggering button on remote controller or the television receiver body for example, the LED-backlit area source does not brighten at once; But increase brightness by blank screen state gradual slow, with give one of eyes of user by dark to the bright procedure of adaptation.Wherein, navigation keys can be designed to specific keys or any key or certain specific keys mode, for example single depression button, or continuous several times pressing keys.In addition, in order not influence other people rest within doors, the eyes that also do not stimulate the user simultaneously, generally, the acquiescence brightness of night-light pattern is darker soft light.
