Description

Needle cleaning dispensing system {Dispensing system capable of needle cleaning}

The present invention relates to a needle cleaning application system.

Portable electronic devices such as smart phones and tablet PCs are being released in various sizes according to their functions and user preferences. Recently, a large screen display is preferred for securing wide visibility and convenience of operation. In addition, in an environment where taking pictures and taking videos has become commonplace, a camera device with improved performance and a technology capable of securing high-quality images are required.

In accordance with this trend, a full-screen display is being applied to the latest portable electronic devices. A full-screen display increases the front display area by minimizing bezels, increasing screen immersion and minimizing unnecessary areas to enhance the aesthetics of the product.

In a full-screen display, in order to maximize the screen, only the camera hole is left in the front display area (see FIG. 1), or only the camera hole and the peripheral portion are left in the edge notch and filled with the display.

However, in order to implement a full-screen display, when a camera hole (CH) is created in the display device 10 of the portable electronic device and the camera device 30 is mounted therein, as shown in FIG. 2, the display A light leak phenomenon occurs in which light emitted from the device 10 leaks through the inner wall of the camera hole CH. In FIG. 2 , reference numeral 11 denotes a display panel and reference numeral 12 denotes a cover glass.

When the light emitted from the display device 10 flows into the camera lens, the image quality of the camera is distorted and the picture quality is affected. In particular, when the camera is used in a dark night, the effect of light emitted from the display device 10 is greater.

In order to prevent such a light leakage phenomenon, a method for black processing the inner wall of the camera hole CH of the display device 10 has been devised.

However, it is very difficult for a small-diameter needle to enter the camera hole CH and spray the light blocking agent onto the inner wall of the camera hole CH without clogging.
