Abstract: An electronic device may have display layers and other structures. A layer of liquid adhesive may be patterned onto a structure. The liquid adhesive may be pre-cured to increase the viscosity of the liquid adhesive and to partially shrink the liquid adhesive. The structure to which the liquid adhesive has been applied may be laminated to another structure. During lamination, the pre-cured liquid adhesive may be compressed between the structures that are being laminated. The adhesive may then be fully cured to bond the structures together. The thickening of the liquid adhesive during pre-curing helps control the spread of the adhesive. The shrinking of the liquid adhesive helps prevent stresses from developing that could lead to visible stress-induced artifacts following curing.

Abstract: A test device includes a transformer, a loop analyzer, and a protection circuit. The protection circuit includes a control unit, a signal acquisition and amplification unit, and an electronic switch. When the loop analyzer outputs a signal, the signal acquisition and amplification unit acquires the signal output from the loop analyzer, amplifies the acquired signal, and outputs the amplified signal to the control unit.

If the digital signal is greater than the reference value, the control unit outputs a control signal to the electronic switch, to turn off the electronic switch. The signal output from the loop analyzer cannot be transmitted to a buck circuit.
