Problems solved by technology

In this case, it is easy for the operator to make a wrong judgment or make a wrong setting.
In addition, when the connection method of the 4-wire or 5-wire resistive touch screen is not compatible with the connection method of the default four-pin connector, the design needs to be changed, causing inconvenience in manufacture and use
[0005] It can be seen that the above-mentioned existing controllers are applicable to 4-wire or 5-wire resistive touch screens at the same time. Obviously, there are still inconveniences and defects in the structure and use, and it is urgent to be further improved.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The invention relates to a device and a method for detecting the connection mode of a 4-wire or 5-wire resistive touch screen. The device comprises five pins and a detector, wherein the detector provides a high potential and a low potential for the two of the five pins at two ends so as to judge whether the 4-wire or 5-wire resistive touch screen is connected in a way of judging whether the pins at the two ends are on or not.

Description

technical field [0001] The present invention relates to a device and method for detecting a 4-wire or 5-wire resistive touch screen, in particular to a device and method for detecting a wiring mode in which a 4-wire or 5-wire resistive touch screen shares the same connector. Background technique [0002] Figure 1A It is a schematic diagram of a traditional resistive touch screen 10, which includes an upper panel 102 and a lower panel 104, and some insulators 106 are scattered between the two panels. When the resistive touch screen 10 is pressed by an external force, the pressured part of the upper panel 102 will contact the lower panel 104 due to the pressure. Therefore, the touch position can be identified by detecting the electrical signal between the two panels. [0003] Figure 1B It is a schematic diagram of a traditional 4-wire resistive touch screen, in which 4 wires are respectively connected to two sides on different sides of the upper panel 102 and the lower pan...
