Embodiment Construction

[0028] Next, components of the present invention will be described.

[0029] (touch screen)

[0030] Since the resistive film driving method targeted by the present invention is roughly divided into touch screens, it has been proposed to be divided into a 4-wire resistive film method (hereinafter referred to as "4-wire type") and a 5-wire resistive film method (hereinafter referred to as "5-wire type"). Mode"). The characteristic of the 4-wire resistive film method is accurate positional accuracy. On the other hand, the characteristic of the 5-wire resistive film method is high durability. Therefore, the user can arbitrarily select a driving method in consideration of this characteristic. An 8-wire resistive film method is also known as a method using the same operating principle as the 4-wire method. The 8-wire resistive film system is also treated in the same manner as the 4-wire system in this specification.

Abstract

A control unit for a touch screen, which controls a first touch screen driven by a first driving method and a second touch screen driven by a second driving method, comprising: a first control circuit part corresponding to the first driving method; a second a control circuit section corresponding to the second driving method; a connector capable of connecting the first touch panel and the second touch panel; a driving method determination section determining a driving method of the touch panel connected to the connector; and a first selection section , which selects the control circuit unit based on the driving method determined by the driving method determining unit. In this way, touch screens with different driving modes can be driven by one control unit.

Description

technical field [0001] The invention relates to a control unit for a touch screen. Specifically, it relates to a control unit for a touch panel that can be used for different drive methods in a touch panel using a resistive film method. Background technique [0002] As a human interface of a computer system represented by a POS system, a touch panel is used. As a driving method for this touch panel, there is a resistive film method. In this method, there are a 4-wire resistive film method and a 5-wire resistive film method. According to the usage purpose and usage style of the touch panel, etc., the driving method is selected so as to reflect its characteristics. [0003] In the prior art, a dedicated control unit is prepared corresponding to the selected touch screen driving method. [0004] Please refer to Patent Document 1 and the like as the technology related to this case. [0005] If a dedicated control unit is prepared corresponding to the conventional touch pane...
