Abstract: An apparatus of testing a stick includes a tension unit that applies tension to a stick having openings formed therein and fixes the stick in place, a first testing unit that is spaced apart from the stick and tests a surface of the stick, a light dispersion unit that reflects light emitted from the first testing unit, a distance measurement unit that measures a third distance from a bottom surface of the stick to the light dispersion unit, and a control unit that calculates a second distance from a starting point of a protrusion of the stick tested by the first testing unit to the light dispersion unit, calculates a difference between the second distance and the third distance so as to calculate a height of the protrusion and determines whether the stick is defective or not, based on the height of the protrusion.
Abstract translation: 测试棒的装置包括张力单元,其向具有形成在其中的开口的棒施加张力,并将棒固定在适当位置;第一测试单元,与棒间隔开并测试棒的表面;光分散单元 其反射从第一测试单元发射的光;距离测量单元,其测量从所述棒的底表面到所述光分散单元的第三距离;以及控制单元,其计算从所述第一测试单元的突起的起始点开始的第二距离 通过第一测试单元测试到光散射单元的棒,计算第二距离和第三距离之间的差,以便计算突起的高度,并且基于突起的高度来确定棒是否有缺陷 。

Abstract: An organic light-emitting display apparatus includes a substrate; thin film transistors; a protective layer that includes a plurality of concave-convex units disposed in a pixel area; an organic light-emitting device disposed on the protective layer; and an encapsulation unit that covers the organic light-emitting device. Each of the concave-convex units protrudes from a surface of the protective layer. The organic light-emitting device includes a pixel electrode, an emission layer, and an opposite layer sequentially stacked on the concave-convex unit, and a distance between the pixel electrode and the opposite electrode is determined by 5%≤(a/b)≤18%, wherein ‘a’ is a vertical distance with respect to the surface of the protective layer between the pixel electrode and the opposite electrode and ‘b’ is a minimum distance between the pixel electrode and the opposite electrode.
