    摘要： A wafer test equipment system includes a performance board connected to a tester head of a tester. A universal block printed circuit board is positioned on the performance board, directly connecting a plurality of normal signal lines to a probe card and dividing each of a plurality of power signal lines into multiple paths and connecting them to the probe card. A cable assembly transfers the normal signal lines and the power signal lines between the universal block printed circuit board and the tester head. The cable assembly is soldered directly to the universal block printed circuit board in a perpendicular direction through a center portion of the performance board. A probe card is removably secured to the performance board including the universal block printed circuit board. The probe card includes an interposer on an upper surface thereof, a ceramic multi-layer substrate positioned below the interposer, and a plurality of needles positioned below the ceramic multi-layer substrate on a lower surface thereof opposite the upper surface.

    摘要： The present invention relates to a display apparatus comprising a light emitting element supplying light, and a switch to switch on and off power, which is supplied to the light emitting element. A comparing unit compares a predetermined first reference voltage and an output voltage which is proportional to a current applied to the light emitting element. A controller compares a comparison voltage output, which is a comparison result of the comparing unit and a predetermined second reference voltage, in order to control the switch to be switched on and off. Accordingly, the present invention provides a display apparatus and control method which precisely controls a size of a current applied to a light emitting element.
