Description
Technical field
The present invention relates to a kind of display panels, especially can effectively prevent static discharge (Electrostatic Discharge, ESD) display panels of Po Huaiing about a kind of.
Background technology
Liquid crystal indicator has that volume is little, power consumption is low and characteristics such as radiation is few, is widely used in fields such as display, LCD TV, mobile phone and notebook computer, and becomes the main flow in market gradually.Liquid crystal indicator comprises a display panels and a module backlight.This display panels comprises the non-display area of a viewing area and adjacent this viewing area.This viewing area comprises many drive wires.This drive wire is used for transmitting this display panels and shows required driving voltage, and it generally includes turntable driving line and data-driven line.This non-display area comprises many short bars (Shorting Bars).This short bar is electrically connected the corresponding driving line respectively.This short bar is electrically connected with outside line, is used for acceptance test voltage, and cooperates external instrument to test the short circuit and the open loop state of this drive wire.
This display panels make and assembling process in, no matter be that various machinery and equipment move, phenomenon that human body contact or display panels itself all may cause static discharge because of accumulating electrostatic charge.Because the circuit and the element of this display panels are very fine, if there is the phenomenon of static discharge to produce the consequence that causes this display panels to be scrapped easily.For solving the low excessively problem of yield that the static discharge phenomenon causes this display panels, industry proposes a kind of electrostatic defending measure, promptly the end of this turntable driving line and this data-driven line is made into tip shape, and makes one first metal tape and one second metal tape in non-display area.This first metal tape and the second metal tape ground connection.This first metal tape comprises first main part and many vertical minor faces that are connected this first main part that is parallel to each other with this turntable driving line.The end that the minor face of this first metal tape does not connect this first main part is made into tip shape, and the end of itself and this data-driven line is oppositely arranged one by one.Equally, this second metal tape comprises second main part and many vertical minor faces that are connected this second main part that is parallel to each other with this data-driven line.The end that the minor face of this second metal tape does not connect this second main part is made into tip shape, and the end of itself and this turntable driving line is oppositely arranged one by one.
When the exterior static electric charge is invaded this display panels, because of the outer path that provides the exterior static electric charge to enter this drive wire is provided for short bar and outside line electrical connections, the end of the end of this turntable driving line and this data-driven line can be accumulated the partial electrostatic electric charge.By the point discharge effect, the electrostatic charge of the end of the end of this turntable driving line and this data-driven line is transferred to this first metal tape and this second metal tape, thereby discharges by the ground connection of this first metal tape and second metal tape.
Yet, the electrostatic charge of the end of this turntable driving line and this data-driven line is accumulated in this electrostatic defending measure only release portion, still have the partial electrostatic electric charge to enter this viewing area interior zone, and be accumulated in this viewing area interior zone, as the intersection of this turntable driving line and this data-driven line.And the intersection of this turntable driving line and this data-driven line is a static discharge probability of damage larger part usually, and the adverse consequences that static discharge causes this turntable driving line and this data-driven line short circuit or disconnection so takes place.So adopt the display panels of above-mentioned electrostatic defending measure to fail discharge electrostatic charges more all sidedly, promptly itself and the static discharge that prevents not yet in effect destroy this display panels.
Summary of the invention
Fail the problem of discharge electrostatic charges more all sidedly in order to solve display panels, be necessary to provide a kind of display panels of discharge electrostatic charges more all sidedly.
A kind of display panels, it comprises the non-display area of a viewing area and adjacent this viewing area.This viewing area comprises many drive wires, and these many drive wires define pixel region.This non-display area comprises many short bars and many vacant lines, this short bar is used for acceptance test signal and be transferred to this drive wire, each this vacant line one end is electrically connected with a short bar, and has at least two other ends that are connected to the vacant line of different short bars to be oppositely arranged.
A kind of display panels, it comprises the non-display area of a viewing area and adjacent this viewing area.This viewing area comprises many drive wires.This non-display area comprises many short bars and many vacant lines, and this short bar is connected to this drive wire, and each this vacant line one end is electrically connected with a short bar, and the other end of at least two vacant lines is oppositely arranged, and is used for release electrostatic.
With respect to prior art, the electrostatic charge that this display panels is invaded by this vacant line transmit outer also makes this static charge buildup at the other end of this vacant line, thereby this electrostatic charge fails to invade this viewing area.And, being oppositely arranged by at least two these vacant line other ends, the discharge of the place of being oppositely arranged of this vacant line of this electrostatic charge outside this viewing area, thereby discharge electrostatic charges more all sidedly prevent that effectively static discharge from destroying this display panels.
