Abstract: A display device includes a pixel array substrate and a circuit board. The pixel array substrate has a first surface, a second surface opposite to the first surface, and a first side surface connecting the first surface and the second surface. Multiple bonding pads are located on the first surface. The circuit board is bent from above the first surface of the pixel array substrate to below the second surface. The circuit board is electrically connected to the bonding pads and includes a thermoplastic substrate. The thermoplastic substrate includes a third surface facing the pixel array substrate and a fourth surface opposite to the third surface. The thermoplastic substrate includes a first bend formed by thermoplastics.

Abstract: The present invention provides a control circuit for speed and rotational direction of a fan, including a signal conversion unit, a processing unit, and a drive unit. The signal conversion unit converts the received input signal into a DC level signal. The processing unit determines to generate a plurality of control signals for the fan based on the received DC level signal and at least one preset voltage therein to drive the drive unit, further controlling the rotational speed or clockwise/counter-clockwise rotation of the fan, whereby to reduce the cost and increase the layout space.
