Abstract:
In a capacitance sensing analog circuit of a touch panel sensing circuit, by raising a magnitude of a current flowing through a sensing capacitor to form an amplified sensing capacitance, while sensing the amplified sensing capacitance with the aid of pulse width modulation signals, higher resolution of the original sensing capacitance may thus be achieved. Besides, by using a self-calibrating capacitance sensing circuit on the touch panel sensing circuit, linear errors and DC errors of an output signal of the capacitance sensing analog circuit may be filtered off, and thereby resolution of a capacitance amplifying ratio may be effectively raised so as to relieve errors within the capacitance amplifying ratio caused by noises.

Abstract:
A capacitance sensing circuit for a touch panel includes an analog capacitance-detecting circuit, a PWM-to-digital circuit and a self-calibration circuit. The analog capacitance-detecting circuit detects the capacitance of the touch panel based on a charging current, and converts the detected capacitance into a PWM control signal. The PWM-to-digital circuit converts the PWM control signal into a sensing count value based on a clock signal. The self-calibration circuit adjusts the value of the charging current or the frequency of the clock signal according to the difference between the range of the sensing count value and a predetermined detecting range. The predetermined detecting range can thus be adjusted for matching the range of the sensing count value.

Then, a second substrate is bonded on the functional switches or conducting lines, and the first substrate is thinned to a predetermined thickness subsequently. Afterwards, a flexible third substrate is adhered on the first substrate, wherein the first substrate is sandwiched between the second substrate and the third substrate. Finally, the second substrate is removed.

A method of forming poly-silicon thin film transistors is described. An amorphous silicon thin film transistor is formed on a substrate, and then the Infrared (IR) heating process is used. A gate metal and source/drain metal are heated rapidly, and conduct heat energy to an amorphous silicon layer. Next, crystallization occurs in the amorphous silicon layer to form poly-silicon. Therefore a poly-silicon thin film transistor is produced.
