Abstract
The invention relates to a method for realizing the light emission of a base and the color synchronization of displayed pictures, comprising a base of a display device and a light emission control circuit. The method is characterized by comprising the following steps that: (1) an LED (Light Emitting Diode) lamp controlled by the light emission control circuit is arranged on the base; (2) RGB (Red Green Blue) data information of a pre-displayed picture is acquired, and a group of RGB data closest to the color of the area is obtained by means of an optimization algorithm; and (3) the closest RGB data are sent to the light emission control circuit, and the light emission control circuit controls the LED lamp to emit light according to the RGB data in order to exhibit certain light halo or pattern effect. With the method, the light halo is formed by reflecting the light emitted by the base onto desktop so that a light, dreamlike and decorative effect is brought to the display area, competitive power of a product is enhanced, and a great market value is achieved.
Description
Technical field
The present invention relates to a kind of display base synchronous light-emitting technology, particularly a kind of luminous and synchronous method of display frame color of base that realizes.
Background technology
Along with the variation of market product, now the product pursued of people not only requires good product quality, and to the profile of product also very attention, if can give the special impression of people on product appearance, that certainly will improve competitiveness of product.At present the base major part of display or TV is only as a kind of additional accessory of support function, it is the secondary element in the entire product shape-designing, so major part does not have lighting function, even it is main having indivedual light-emitting bases also to be bill coloured light, and focus mostly on a certain regional area in the visual range of front of light-emitting zone.Therefore, if can provide a bright spot for display device, will bring huge marketable value to display device at base.
Summary of the invention
In view of this, the invention provides a kind of luminous and synchronous method of display frame color of base that realizes, can realize that reflexing to desktop by the light that base sends forms the effect that halation sets off the slim and graceful, dreamlike of viewing area by contrast and decorates.
For achieving the above object, the present invention adopts following scheme to realize: a kind of luminous and synchronous method of display frame color of base that realizes, the base and the emission control circuit that comprise display device, it is characterized in that, comprise the steps: (1), at the LED lamp of base setting by emission control circuit control; (2), gather the RGB data message of pre-display frame, by optimized Algorithm will obtain one group with the immediate RGB data of this field color; (3), should immediate RGB data send to emission control circuit, described emission control circuit is luminous according to this RGB Data Control LED lamp, to present certain halation or pattern effect.
The display device of design according to the present invention, its base can send according to the main body color of display frame and set off halation accordingly, reaches the effect of decoration, and the present invention does not need the main body circuit of display device is done significant improvement, cost is low, can effectively improve competitiveness of product.

Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the invention provides a kind of luminous and synchronous method of display frame color of base that realizes, comprise the base and the emission control circuit of display device, it is characterized in that, comprise the steps:
(1) at the LED lamp of base setting by emission control circuit control;
(2) the RGB data message of the pre-display frame of collection will obtain one group and the immediate RGB data of this field color by optimized Algorithm;
(3) should immediate RGB data send to emission control circuit, described emission control circuit is luminous according to this RGB Data Control LED lamp, to present certain halation or pattern effect.
The display picture displayed is made up of pixel, and each pixel comprises the data message of R, G, B, reads the register address of master controller storage pixel point RGB data message by software, can get access to any pixel of screen (R, G, B) data.Master controller of the present invention obtains the RGB data message of pre-display frame in real time, pass through optimized Algorithm, here, we can be by analyzing the RGB data of gathering picture area, dim spot (RGB numerical value is all near 0) is judged, the data of giving up dim spot are weighted the calculating of mean value with the data of remaining pixel, can obtain one group with the immediate RGB data of this field color; By helping controller GPIO mouth level, immediate data are sent then.This sending method can be: the 16 system data step-by-steps that will send send, try to achieve the value (1 or 0) that desire sends the position by bit arithmetic, remove to control the level (draw high or drag down) of GPIO then with software, and these data are sent by the sequential of LED drive IC.
In present embodiment, the LED drive IC that described emission control circuit is selected for use is TLS3002, and this chip provides 3 constant current output channels, built-in 256 grades GTG control PWM modulation function.What adopt is Manchester's cde mode single line transmission data, and data transmission range is in the 100KHZ-1MHZ scope.As shown in Figure 2, control flow is as follows: by the GPIO mouth of master controller, the RGB data that collect are sent to TLS3002 according to the form of Frame, first chip is for receiving the chip of data at first, the data layout of chip is: bit 0 (flag)+8 ' bit xxxxxxxx(output port 2 data 1 ' bit0 (flag)+8 ' bit xxxxxxxx(output port, 1 data)+1 ')+1 ' bit 0 (flag)+8 ' bit xxxxxxxx(output port, 3 data), or x is 10.Every LED lamp is connected with corresponding TLS chip, and every TLS chip receives the corresponding region RGB data that master controller sends.
LED light fixture of the present invention has several, here we are example with three, those LED lamps can be located at susceptor surface, also can be as shown in Figure 3, under the base luminescent lamp strip is set, the light that each lamp band sends and the screen color realtime uniform in corresponding zone, the light part that the lamp band sends is transmitted into the base lower surface back reflection to desktop, a part is transmitted directly to desktop, please continue with reference to Fig. 3, LED lamp 3 is located in the light belt 2 of base 1 lower surface among the figure, the information of the picture area pixel of each LED lamp correspondence of system acquisition will comprise the data of color in the RGB three after the optimization process, every kind of color data size is 0-0XFF, 0 this color of expression does not exist, and 0XFF represents this colour brightness maximum.The color relation of each pixel of display picture is made up of three kinds of colors of RGB, and its RGB size of data of different colors is also different.
Here what deserves to be mentioned is, display of the present invention comprises that televisor, LCD etc. are used to show the equipment of watching, here be noted that base of the present invention and not merely refer to discoidal supporting seat, it can also be other shapes, also can be integrated, have the chassis of supporting role with display device.Present embodiment is in order better to reach reflection, to set off effect, and the lower cover of described base is a transparent or semitransparent light guide plate, and this light guide plate surface or inside can be provided with some patterns, under the shining upon of LED lamp, present pattern effect.The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
