In the voltage for adjusting the marginal portion, make the color of the marginal portion consistent with adjacent pixel color.
Used as one of which implementation method, the marginal portion is in black when the switch element does not work.
Used as one of which implementation method, the electrochromic material shows red, green, blueness successively with voltage increase
With it is transparent.
Used as one of which implementation method, the electrochromic material filling rate of the marginal portion is more than 50%.
Used as one of which implementation method, described Frame-free liquid crystal display device also includes being filled in the switch element
And the photic zone between the marginal portion of the black matrix unit.
Used as one of which implementation method, the switch element is TFT (thin film transistor (TFT)) substrate.
Used as one of which implementation method, the switch element is switching tube.
Another object of the present invention is to provide a kind of display methods of described Frame-free liquid crystal display device, including：
Light back light unit；
The voltage of the marginal portion for being applied to corresponding black matrix unit is adjusted by switch element, makes the marginal portion
Color it is consistent with adjacent pixel color.
The present invention is filled with electrochromic material by by the marginal portion of black matrix unit, can be applied to by control
The display situation of voltage and back light unit on electrochromic material controls the light face of the marginal portion of black matrix unit
Color pixel region adjacent thereto is identical, not only can guarantee that shaded effect but also can realize that Rimless shows.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
Refering to Fig. 1, the Frame-free liquid crystal display device of the embodiment of the present invention is including switch element 10, located at switch element 10
On black matrix unit 20 and located at the lower section back light unit 40 of switch element 10, black matrix unit 20 includes being disposed on adjacent
Center section and the marginal portion for being arranged on periphery between two pixels, are filled with electrochromic material in marginal portion.Its
In, switch element 10 is used to adjust the voltage of marginal portion, makes the color of marginal portion consistent with adjacent pixel color.This
In, preferably the electrochromic material filling rate of marginal portion is more than 50%, makes its electrochriomism better performances.
Meanwhile, one layer of photic zone can be also also filled between the marginal portion of switch element 10 and black matrix unit 20
30, the photic zone 30 is made up of materials such as epoxy resin, curing agent, coupling agents, printing opacity effect can be played, while can also realize
Black matrix unit 20 is relatively fixed with the position of switch element 10.
Switch element 10 is overlap up and down with the marginal portion of black matrix unit 20, and the electrochromic material of marginal portion can
Think inorganic material, such as color quantum point, or organic material, marginal portion when switch element 10 does not work darkly
It is in black when color, i.e. applied voltage are 0.For inorganic material, red band energy gap is minimum, and light radiation transition most easily occurs, green
Color takes second place, and blue required voltage is maximum.In the display device course of work, the color of each several part in display picture can become in real time
Change, i.e., in the course of the work, the voltage for being applied to the marginal portion of black matrix unit 20 is become in real time according to display drive signals
Change, make the color of electrochromic material all the time with the solid colour of adjacent pixel region, so, you can realize visually without
Frame.
As one of which preferred embodiment, electrochromic material shows red (R), green successively with voltage increase
(G) it is, blue (B) and transparent.I.e. when switch element 10 does not work, the display black of black matrix unit 20 of marginal portion, when logical
When crossing switch element 10 and gradually heightening the voltage being applied on electrochromic material, the color of electrochromic material successively R, G,
Change between B, W (white, i.e., transparent).
As shown in Fig. 2 switch element 10 can be TFT substrate.TFT substrate is provided with black matrix unit 20, black matrix list
The opening of densification is formed in unit 20, R, G, B pixel are regularly formed in the respective openings of the black matrix unit 20, are filled with
