Patent number: 11223020Abstract: A display may have an array of organic light-emitting diodes that form an active area on a flexible substrate. Metal traces may extend between the active area and an inactive area of the flexible substrate. Display driver circuitry such as a display driver integrated circuit may be coupled to the inactive area. The metal traces may extend across a bend region in the flexible substrate. The flexible substrate may be bent in the bend region. The flexible substrate may be made of a thin flexible material to reduce metal trace bending stress. A coating layer in the bend region may be provided with an enhanced elasticity to allow its thickness to be reduced. The flexible substrate may be bent on itself and secured within an electronic device without using a mandrel.Type: GrantFiled: March 31, 2017Date of Patent: January 11, 2022Assignee: Apple Inc.Inventors: Zhen Zhang, Yi Tao, Paul S.

Publication number: 20180088728Abstract: This relates to a force-sensitive touch screen including a metallization layer for force sensing. In some examples, the force-sensing metallization layer can be deposited between a color filter layer and a thin film transistor (TFT) layer (including an array of TFTs) of the touch screen. In some examples, the metallization layer can be electrically coupled to a patterned conductive layer. Together, a force-sensing metallization trace of the metallization layer and a patterned conductor of the patterned conductive layer can act as a force sensor. Additionally or alternatively, the device can include a force-sensing metallization layer and a conductive layer (patterned or not) located beneath the TFT layer (i.e., rather than between a color filter layer and the TFT layer).Type: ApplicationFiled: September 14, 2017Publication date: March 29, 2018Inventors: Joshua G.
