Embodiment Construction

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

[0028] See also 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 dummy pixel 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 trace 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. A virtual OLED D2 is arranged in the virtual opening area P22. The virtual OLED D2 includes an anode 221 and an organic The light-emitting layer 222,...

Abstract

The present invention provides an OLED display panel, using the characteristics of forward conduction and reverse cut-off of OLED, the cathode (223) of the dummy OLED (D2) in the dummy pixel (P2) is connected to the power supply line (VDD), and the anode (221) Connect the cathode (123) of the normal OLED (D1) in the normal light-emitting pixel (P1), so that the dummy OLED (D2) becomes a reversely connected diode, which acts as an electrostatic protector for electrostatic protection, and can reduce the impact on the display panel. Electrostatic damage, and the dummy OLED (D2) is located in the opening area of ​​the dummy pixel (P2), which makes full use of the dummy pixel area and does not need to set up electronic components specially used for electrostatic protection, which contributes to narrowing the frame of the OLED display panel and improving Opening rate.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] Static electricity is a natural phenomenon that exists objectively, and it can be produced in many ways, such as contact, friction, and induction between electrical appliances. Static electricity has the characteristics of long-term accumulation, high voltage, low power, low current and short action time. The actions of the human body 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 to electronic and electrical products. [0003] The problem of electrostatic protection also exists in the display panel. The usual electrostatic protection methods in the prio...
