Description
Technical field
The utility model belongs to display technology field, more particularly, to a kind of colored filter and display panel.
Background technology
With the development of science and technology, flat-panel monitor has substituted bulky CRT monitor increasingly to go deep into the daily of people
In life.At present, conventional flat-panel monitor includes LCD (Liquid Crystal Display, liquid crystal display) and OLED
(Organic Light-Emitting Diode, Organic Light Emitting Diode) display.Especially LCD display have it is frivolous,
The advantages that energy-conservation, low-power consumption, it has been widely used in the electronic equipments such as TV, computer, mobile phone, digital camera.
Its operation principle is mainly that the ordered state of liquid crystal molecule, the light energy as caused by backlight are controlled using electric field
It is no by liquid crystal molecule to reach the display effect of light and shade on display screen.
Display panel is most important part in flat-panel screens.The display panel includes array base palte (TFT bases
Plate) and the array base palte be oppositely arranged colored filter (CF substrates), be filled between array base palte and colored filter
Liquid crystal, wherein, the electrode on the array base palte and colored filter adjusts the external world by controlling the rotation of liquid crystal molecule
The percent of pass of light, meanwhile, the purpose for reaching colored display is engaged with colored filter.The display panel also includes being used to glue
Close the sealant of array base palte and colored filter.During display panel is made, array is located at using sealant sealing
Liquid crystal between substrate and colored filter, form liquid crystal cell.
Fig. 1 shows the sectional view of display panel in the prior art, as shown in figure 1, display panel 1 includes what is be oppositely arranged
Colored filter 10 and array base palte 20, the liquid crystal layer 30 between colored filter 10 and array base palte 20, and seal
The firmly glue frame 40 of liquid crystal layer, the edge that array base palte extends colored filter are provided with pad 21, and pad 21 includes being used for point
The region of conductive silver glue 50, conductive silver glue 50 are used to connect the electrode on the electrode and array base palte 20 on colored filter 10.
Such as will be connected positioned at 10 outermost transparent conductive ITO layer of colored filter with the public electrode on array base palte 20,
So that colored filter to be grounded, for shielding influence of the external electrical field to liquid crystal, and remove what is accumulated on colored filter 10
Electrostatic.
Colored filter 10 includes glass substrate 11 and towards the black matrix (Black on the side of array base palte 20
Matrix, BM) 12 and the color blocking layer 13 that is arranged between the black matrix, in addition to transparent conductive ITO layer 14, it is arranged on glass
Glass substrate 11 is on a side surface of black matrix 12.
Fig. 2 shows the top view of display panel in the prior art, as shown in Fig. 2 shown display surface 1 includes viewing area

In the prior art, the distribution of black matrix includes edging design and non-edging designs two kinds.Designed for non-edging, it is black
The edge of matrix distance colored filter is 0.2~0.4um, and this design has the problem of dark-state periphery bad light-leaking, especially
It is the close quarters that a large amount of parallel metal cablings are equipped with close margin location, this problem is more serious.And designed for edging,
Black matrix flushes with the edge of colored filter, in the absence of the bad problem of dark-state periphery light leak.
The resistance value of traditional black matrix material is about 106~107Ω, not completely insulator, the resistance one of flat layer material
As it is big more, about 1015~1016Ω.The common electric voltage and pixel voltage of large size TFT-LCD are general higher, due to electric capacity
Device effect, it can sense in black matrix and produce certain electric charge, i.e., in the presence of certain induced voltage.After tested black matrix have+5~
+ 7V induced voltage, it is close with dark-state pixel voltage or public electrode voltages (Vcom about+8V).But for edging design
Black matrix, during a conductive silver glue, the black matrix in non-display area B can be caused conductive, and then cause entirely to show
The black matrix 12 of panel is conductive, i.e., is contacted with ground connection end in contact or other low-voltages, and electric charge export, induced voltage declines, its with
Dark-state pixel voltage or public electrode voltages difference increase, cause liquid crystal deflection, and pixel is shinny, because green pixel is shinny obvious,
Therefore dark-state greening phenomenon occurs, has a strong impact on the quality of product.
