Abstract
An electronic device may be provided with a display and a multi-layer printed circuit. Integrated circuits and other components may be mounted to the multi-layer printed circuit. The display and multi-layer printed circuit may share a common layer formed from a flexible substrate. The flexible substrate may have portions that are integrated into the display and portions that are integrated into the multi-layer printed circuit board. The flexible substrate may contain patterned conductive traces that are used to route signals from components in the multi-layer printed circuit to display circuitry such as a display driver integrated circuit. An array of thin-film transistors may be used to control the emission of light from the display and may be formed on portions of the flexible substrate that are integrated into the display. The display may be a flexible display that includes an array of organic light-emitting diodes.
