Problems solved by technology
[0005] On the one hand, due to the height H of the pillar 14 from the substrate 15 1 and in-plane height H 2 , that is, the height of the display area 16 is the same, if the filling amount of the filling glue 13 exceeds, then during the pressing process of the cover plate 17, the excess filling glue 13 will overflow the range delineated by the cylinder 14, and the width of the overflowing glue is difficult to control; If the filling glue 13 overflows into the display area 16, it will cause abnormal display
[0006] On the other hand, if the filling amount of the filling glue 13 is insufficient, air bubbles will appear in the area of the blind hole 12 during the pressing process of the cover plate 17, which will affect the packaging performance of the OLED display.

The invention relates to the technical field of display equipment, and provides an OLED panel and a dispensing method thereof. The OLED panel comprises a display area arranged on an array substrate and a blind hole area arranged in the display area, and the blind hole area comprises a hole area, a hole area and a hole area, the wiring area surrounds the hole area; the blocking piece is arranged on the wiring area, the blocking piece comprises a first annular blocking piece and a second blocking piece, the first annular blocking piece surrounds the hole area and is provided with an overflow glue outlet, the second blocking piece at least surrounds the overflow glue outlet, and the height of the second blocking piece is at least equal to that of the display area. And a glue overflowing space is formed between the first annular stopper and the second stopper. Through the structural design of the blocking piece, the overflowing glue outlet and the overflowing glue space are formed, filling glue overflows from the overflowing glue outlet to the overflowing glue space when glue is dispensed on the OLED panel, the glue filling amount is ensured, overflowing glue is controlled within a controllable range, and the failure risk in the glue dispensing process of the OLED panel is avoided.
Description
technical field [0001] The invention relates to the technical field of display devices, in particular to an OLED panel and a dispensing method thereof. Background technique [0002] The camera installation method of the OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen is usually to open a blind hole in the display area, and the camera is arranged under the blind hole. [0003] figure 1 Show the main structure of the existing OLED display, refer to figure 1 As shown, the camera 11 is arranged corresponding to the blind hole 12, and the area of the blind hole 12 is filled with a filler 13 to realize packaging. On the periphery of the area of the blind hole 12, a circle of cylinders 14 is arranged to prevent the filling glue 13 from overflowing. [0004] The existing structure of blocking the overflow of the filling glue 13 through a circle of cylinders 14 has the following problems: [0005] On the one hand, due to the height H of the pi...
