Abstract
Description

随着智能移动终端的普及,显示面板技术得到广泛应用,其发展越来越迅速。With the popularity of smart mobile terminals, display panel technology has been widely used, and its development is getting faster and faster.
如图1所示,显示面板1包括阵列基板11、彩膜基板12、第一配向膜13、第二配向膜14、第一支撑柱15以及第二支撑柱16。其中,阵列基板11和彩膜基板12相对设置,第一配向膜13设置在阵列基板11靠近彩膜基板12的一侧,第二配向膜14设置在彩膜基板12靠近阵列基板11的一侧。第一支撑柱15和第二支撑柱16设置在第一配向膜13和第二配向膜14之间,并固定在第二配向膜14上。As shown in FIG. 1, the display panel 1 includes an array substrate 11, a color filter substrate 12, a first alignment film 13, a second alignment film 14, a first support pillar 15 and a second support pillar 16. The array substrate 11 and the color filter substrate 12 are oppositely arranged, the first alignment film 13 is arranged on the side of the array substrate 11 close to the color filter substrate 12, and the second alignment film 14 is arranged on the side of the color filter substrate 12 close to the array substrate 11 . The first support column 15 and the second support column 16 are disposed between the first alignment film 13 and the second alignment film 14 and fixed on the second alignment film 14.
其中,在显示面板1未受到外力作用时,第一支撑柱15可以起支撑作用。当显示面板1受到外力作用时,第二支撑柱16可以起辅助支撑作用。然而,当外力较大时,第一支撑柱15和第二支撑柱16会发生滑动,划伤第一配向膜134,造成显示面板1液晶配向紊乱。并且第一支撑柱15和第二支撑柱16高度较高,滑动范围较大,造成第一配向膜13被划伤范围过大。Wherein, when the display panel 1 is not subjected to an external force, the first support pillar 15 may play a supporting role. When the display panel 1 is subjected to an external force, the second support column 16 may play an auxiliary supporting role. However, when the external force is large, the first support pillar 15 and the second support pillar 16 may slide, scratching the first alignment film 134, causing the liquid crystal alignment disorder of the display panel 1. In addition, the height of the first support column 15 and the second support column 16 are relatively high, and the sliding range is large, which causes the scratched range of the first alignment film 13 to be too large.
