Abstract: The invention relates to a touch panel correcting apparatus includes a control module, a processing module, a detecting module, a judging module and a correcting module. The control module is used for generating a controlling signal. The processing module is used for executing a pointing action under a first predetermined manner after receiving the controlling signal. The detecting module is used for detecting the touch panel according to the pointing action under a second predetermined manner and generating at least one detecting result. The judging module is used for executing a predetermined operation according to the at least one detecting result and a predetermined information and generating at least one correcting value. The correcting module is used for correcting the touch panel according to the at least one correcting value.

Abstract: The invention relates to a frequency adjusting apparatus and the method therefor comprising an adjusting module, a comparing module, a processing module and an operating module. The adjusting module generates a frequency signal according to a predetermined signal after receiving a trigger signal and generates N adjusting signal according to N processing signal. The comparing module compares the N adjusting signal with the predetermined signal according to a predetermined manner and generates N comparing result. The processing module generates N processing signal according to the N comparing result. The operating module executes a specific operation with M adjusting signal of the N adjusting signal matching the predetermined rule and generates a operation signal, wherein the frequency of the operation signal is approximately equal to which of the predetermined signal. Wherein N and M are natural numbers and N?M?1, the adjusting module adjusts the operation frequency according to the operation signal.

Abstract: The invention relates to a cursor controlling apparatus for controlling a cursor according to an input information comprising an input module, a processing module and a controlling module. The input module is used for generating the input information. The processing module coupled to the input module is used for generating processing data according to the input information. The controlling module is coupled to the processing module for comparing the processing data with a predetermined value to generate a comparing result and further generating a first control signal or a second control signal corresponding to the processing data and the compared result to control the cursor respectively.

Abstract: The present invention provides A control device for determining 4-wire or 5-wire resistive touch screen, comprising: detecting means for respectively sending 4-wire control instruction and 5-wire control instruction in the period before sending control instructions of fetching X-axis and Y-axis coordinate position, so as to detect whether a 4-wire resistive touch screen or 5-wire resistive touch screen are being attached; control means, in accordance with the detected result of the detecting means, the control device is switched to 4-wire or 5-wire resistive touch screen so as to fetch the coordinate position.
