Embodiment
In order to further illustrate, the embodiment of the present invention provides, and is described in detail below in conjunction with Figure of description.
Refer to Fig. 1, the array base palte that the embodiment of the present invention provides comprises the first transparent electrode layer 1 and the second transparent electrode layer 3 be oppositely arranged; Electrochomeric films layer 2 is provided with between first transparent electrode layer 1 and the second transparent electrode layer 3; Wherein, when showing non-L0 picture, electrochomeric films layer 2 presents through backlight state; When showing L0 picture, electrochomeric films layer 2 presents and blocks backlight state.
Refer to Fig. 2-4, during work, first transparent electrode layer 1 and the second transparent electrode layer 3 apply voltage, when needs show non-L0 picture, first transparent electrode layer 1 and the second transparent electrode layer 3 apply voltage to trigger electrochomeric films layer 2, make electrochomeric films layer 2 present through backlight state, do not affect the image display of liquid crystal panel; When needs display L0 picture, the first transparent electrode layer 1 and the second transparent electrode layer 3 applying voltage to trigger electrochomeric films layer 2, making electrochomeric films layer 2 block backlight state by switching to through backlight state.
From the above-mentioned course of work, whether the electrochomeric films layer 2 in the array base palte that the present embodiment provides can according to showing L0 picture, repeatedly, reversible block backlight state and through backlight state between switch; And, when needs display L0 picture, because electrochomeric films layer 2 presents the state of blocking backlight, this has just fundamentally stopped the generation of L0 light leak, even if liquid crystal molecule state changes or liquid crystal molecule external environment changes, also can not produce L0 light leak, significantly reduce the dark-state brightness of liquid crystal panel, thus improve contrast.In addition, close the display of backlight compared to traditional dark-state, the array base palte that the present embodiment provides can realize the dark-state of each pixel in liquid crystal panel and block backlight control, dark-state is controlled more accurate.In addition, in the array base palte that the present embodiment provides, electrochomeric films layer 2 except can repeatedly, reversible block backlight state and through backlight state between switch, can also use as passivation layer, reduce the cost of manufacture of array base palte.
It should be noted that, in the array base palte provided in above-described embodiment, when electrochomeric films layer 2 presents through backlight state, electrochomeric films layer 2 presents Transparent color under being in non-ater GTG, and therefore the transmitance of electrochomeric films layer 2 is higher; When blocking backlight state, under electrochomeric films layer 2 is in ater GTG, in dark state or black state, therefore relative to presenting through electrochomeric films layer during backlight state, when blocking backlight state, electrochomeric films layer transmitance is lower.It should be noted that, dark state is that all meet electrochomeric films layer 2 and present when blocking backlight state, and the general designation of the color of electrochomeric films layer 2 is not certain particular color concrete.
By above-mentioned analysis, through backlight state and block backlight state time, according to color, the transmitance of electrochomeric films layer 2 and whether present ater gray scale states, the electrochomeric films layer 2 in the present embodiment can also be described from any one following three aspects:
1) from the angle that whether transparent electrochomeric films layer 2 is, the electrochomeric films layer 2 in above-described embodiment can need to make it in clear state and dark state according to display frame, or send out repeatedly between clear state and black state, reversible switching.
2) from the transmitance angle of electrochomeric films layer 2, the electrochomeric films layer 2 in above-described embodiment be can according to display frame need to make its transmitance repeatedly, reversible changing.
3) whether present ater gray scale states from electrochomeric films layer 2, the electrochomeric films layer 2 in above-described embodiment be can need to send out repeatedly between non-ater GTG and ater GTG according to display frame, reversible switching.
Wherein, the transmitance size of electrochomeric films layer 2 can control by the first transparent electrode layer 1 and the second transparent electrode layer 3 apply voltage, when the transmitance of electrochomeric films layer 2 changes, whether the color of electrochomeric films layer 2 and display frame present ater gray scale states also all can there is respective change.Such as, when on first transparent electrode layer 1 and the second transparent electrode layer 3, alive voltage difference of executing is high voltage, electrochomeric films layer 2 is clear state, and transmitance is high, present through backlight state, corresponding display frame shows non-L0 picture under non-ater GTG; When on first transparent electrode layer 1 and the second transparent electrode layer 3, alive voltage difference of executing is low-voltage, electrochomeric films layer 2 is dark state or black state, transmitance is low, presents and blocks backlight state, and corresponding display frame shows L0 picture under ater GTG.
In order to control the transmitance of electrochomeric films layer 2 more accurately, electrochomeric films layer 2 is had under corresponding transmitance and blocks backlight or the function through backlight, need to carry out considered critical to alive voltage difference of executing on the first transparent electrode layer 1 and the second transparent electrode layer 3.Preferably, on the first transparent electrode layer 1 and the second transparent electrode layer 3, alive voltage difference of executing is greater than 0.7V, and namely high voltage is greater than 0.7V; On first transparent electrode layer 1 and the second transparent electrode layer 3, alive voltage difference of executing is greater than 0V and is less than or equal to 0.7V, and namely low-voltage is greater than 0V and is less than or equal to 0.7V; And in the array base palte that above-described embodiment provides, the voltage source mode be applied on the first transparent electrode layer 1 and the second transparent electrode layer 3 is a lot, preferably provided by driving circuit, avoid owing to adopting driving circuit increasing additional circuit, therefore, control circui is simple and convenient.
