Abstract:
This invention discloses a display device mother substrate, a display device substrate and a manufacture method of display device substrate thereof. The display device mother substrate includes a first substrate, a second substrate, a first active area circuit and a first transmission line, wherein a first cutting line is defined between the first substrate and the second substrate. The first active area circuit is disposed on the first substrate and is electrically connected to the first transmission line. The first transmission line includes a display line portion, an end line portion and a middle line portion, wherein the display line portion is electrically connected to the first active area circuit. The middle line portion is disposed on the second substrate, wherein two ends of the middle line portion are electrically connected to the display line portion and the end line portion respectively at the first cutting line. The display device mother substrate is cut along the first cutting line to be separated into the first substrate and the second substrate, wherein the middle line portion is also separated from the display line portion and the end line portion.
Abstract:
This invention relates to a drill structure having cutting blade, comprises a drill tip, a cone top part, head part, cutting part, scrap-guiding slot and drill body. The drill tip forms a top end tip of a cone point, the cone top part is installed underneath the drill tip, its head part is a columnar body takes the cone top part, a pair of blade parts is installed at two halves of the cone top part respectively, the blade parts extend a cutting angle from the cone top part, the scrap-guiding slot is a slope surface extends from the drill tip through the cone top part to the head part, the drill body comprises at least one scrap-release screw line; a scrap-release slope is installed in between the scrape surface and drill tips to enhance the hole-drilling precision, drilling capability and scrap-release capability.
