Problems solved by technology

[0005] The invention provides an OLED display panel, which can solve the problem that in the prior art, when the metal wiring and pixels of the OLED panel are repaired, because the black matrix covers the circuit area, the repair can only be performed from the backlight surface, and the OLED needs to be turned over after the repair is completed. Confirm the repair effect of the display panel, especially for the repair of bright and dark pixels, constantly flipping the OLED display panel, the precise alignment of the front and back of the repair position is difficult, time-consuming and laborious, and increases the probability of OLED display panel fragmentation.

Embodiment Construction

[0024] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figure, units with similar structures are indicated by the same reference numerals, and the dotted lines in the figure indicate that they do not exist in the structure, and only illustrate the shape and position of the structure.

[0025] The present invention aims at repairing the metal wiring and pixels of the OLED panel in the prior art. Since the black matrix covers the circuit area, the repair can only be performed from the backlight surface. After...

Abstract

The invention provides an OLED display panel. The pixel definition layer in the OLED display panel is provided with an opening area and a non-opening area; the opening area and the pixel unit are oppositely arranged, and the non-opening area is provided with a lightproof layer surrounding the pixel unit. The non-opening area is provided with a transparent layer corresponding to a circuit layer, thereby ensuring that the light-emitting surface of the OLED display panel can directly see the repairing effect of the metal wiring in the circuit layer without turning over, reducing the repairing difficulty and reducing the fragment risk caused by turning over the OLED display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] Organic light emitting diode (Organic Light Emitting Display, OLED) display panel has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, near 180° viewing angle, wide operating temperature range, etc. Widely used in smartphones, tablets, full-color TVs, etc. [0003] The driving methods of OLED display panels are divided into two categories: passive matrix type and active matrix type. Among them, OLED has pixels arranged in an array, is driven by a thin film transistor, and belongs to an active matrix type, has high luminous efficiency, and is usually used in a large-sized display panel with high definition. In the active matrix type display panel, according to the light emission direction, it is divided into bottom emission type and to...
