Embodiment Construction

[0027] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0028] Please also see Figure 1 to Figure 4 , The present invention provides an OLED display panel.

[0029] Such as figure 1 and figure 2 As shown, the OLED display panel of the present invention includes a plurality of normal light-emitting pixels P1 arranged in an array, at least one circle of dummy pixels P2 surrounding the plurality of normal light-emitting pixels P1 arranged in an array, and The dummy pixel P2 is far away from the power supply line VDD on the side of the normal light-emitting pixel P1.

[0030] Such as figure 2 As shown, the virtual pixel P2 is divided into a virtual TFT area P21 and a virtual opening area P22, and a virtual OLED D2 is set in the virtual opening area P22, and the virtual OLED D2 includes an anode ...

Abstract

The invention provides an OLED (organic light emitting diode) display panel. By utilizing the characteristics of positive onset and reverse cut-off of an OLED, a cathode (223) of a virtual OLED (D2) in virtual pixel (P2) is connected with a power routing (VDD), and an anode (221) is connected with a cathode (123) of a normal OLED (D1) in normal light-emitting pixel (P1) so as to enable the virtual OLED (D2) to become the diode which is reversely connected and serves as an electrostatic protector with the electrostatic protection function, so that the electrostatic damage to the display panel can be reduced; and in addition, as the virtual OLED (D2) is arranged in an opening region of the virtual pixel (P2), the virtual pixel region is fully utilized, an electronic element specially for electrostatic protection is not needed, frame narrowing of the OLED display panel is facilitated, and the opening rate is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] Static electricity is an objectively existing natural phenomenon, which can be produced in many ways, such as contact, friction, induction between electrical appliances, etc. Static electricity has the characteristics of long-term accumulation, high voltage, low power, low current and short action time. The action of the human body itself or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. Friction electrification and human body static electricity are two major hazards in the electronics industry, which often cause unstable operation or even damage of electronic and electrical products. [0003] The problem of electrostatic protection also exists in the display panel. The usual ESD protection method in the prior art is...
