Description

Display panel

Technical field

The present invention relates to OLED fields, more particularly to a kind of display panel.

Background technology

With need of the consumer to the gradual growth of the interest of information display device and to portable (movement) massaging device Gradual increase is asked, frivolous flat-panel monitor (FPD's) of the display device for substituting cathode-ray tube (CRT) and routine grinds Study carefully and be commercialized and energetically carry out.

So far, become prominent in FPD fields, lighter and more power saving liquid crystal display (LCD).Connect however, LCD is light Receiving apparatus rather than light emitting devices, its in brightness, contrast, visual angle etc. Shortcomings, so can overcome it is this not During the novel display device of foot is actively developing.

Organic Light Emitting Diode (OLED) display device (a kind of novel display device) is self luminous, and it has excellent Visual angle and contrast because it is not required to backlight, OLED display is more frivolous, and in terms of power consumption have it is excellent Gesture.In addition, the advantages of OLED display, is that its available DC low-voltage drives and has faster response speed, and Also there is advantage in manufacturing cost.

Different from LCD or plasma display panel (PDP), the manufacturing process of OLED display only includes deposition and envelope Dress technique, therefore be simple.Moreover, when basis has thin film transistor (TFT) (TFT) as the switch element in each pixel When active matrix scheme drives OLED display, although applying low current, same brightness can be obtained, so LED The advantages of display device, is that it can consume less power and obtain high accuracy and resolution ratio, and can be dimensionally Increase.

Embodiment

Technical scheme is described further below according to specific embodiment.Protection scope of the present invention is unlimited In following examples, these examples are enumerated merely for exemplary purpose without limiting the invention in any way.

Fig. 4 shows the structural representation of the power line of the display panel of one embodiment of the present invention, as shown in figure 4, First power line includes：

A plurality of first conductor wire 301~308 and a plurality of first connecting line 401~407, wherein every first connecting line 401~407 and the connection of at least adjacent two the first conductor wires 301~308.

Each first connecting line can only connect two adjacent the first conductor wires, i.e. the first connecting line 401 only connects first and led The conductor wire 302 of electric wire 301 and first, the first connecting line 402 only connect the first conductor wire 302 and the first conductor wire 303, and first connects Wiring 403 only connects the first conductor wire 303 and the first conductor wire 304, and the first connecting line 404 only connects the He of the first conductor wire 304 First conductor wire 305, the first connecting line 405 only connect the first conductor wire 305 and the first conductor wire 306, and the first connecting line 406 is only The first conductor wire 306 and the first conductor wire 307 are connected, the first connecting line 407 only connects the first conductor wire 307 and the first conductor wire 308, smaller metallic area is obtained with this.

A plurality of first conductor wire 301~308 and a plurality of first connecting line 401~407 are conductive material, such as Copper, silver etc., but not limited to this.

A plurality of first connecting line 401~407 and a plurality of first conductor wire 301~308 can vertical connection, preferably to reduce The length of first connecting line 401~407.

What the spacing of adjacent two the first conductor wires was usually fixed, and the spacing of adjacent two the first connecting lines can be more than Twice of the spacing of adjacent two the first conductor wires, such as the spacing of the first connecting line 401 and the first connecting line 402 are more than first Twice of spacing between the conductor wire 302 of conductor wire 301 and first, relatively large spacing can be reduced more in power line Metallic area, so as to reduce short circuit probability.

The first connecting line no less than two, such as the first conductor wire 301 can be set between adjacent two the first conductor wires And first the connecting line of many places first can be set between conductor wire 302, however it is not limited at the first connecting line 401 1, so as to avoid Because of somewhere first, connecting line causes the problem of being not turned between each first conductor wire being not turned on.

First power line can connect any one in negative electrode and anode, such as the first power line can be VDD or VSS.
