Problems solved by technology

At present, the tools provided by the capacitive screen driver IC solution provider cannot meet the above requirements. In order to improve the test efficiency, the manufacturer usually uses one tester to operate two computers to test, and this method can only improve a little efficiency. The skill requirements of personnel are relatively high, which cannot well meet the requirements of capacitive screen manufacturers

Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] like figure 1 As shown, the test system is composed of four parts: host computer, multi-serial port card, bus transfer board, and signal interface unit. Among them, the host, the multi-serial port card, and the bus transfer base are serially connected in series, and eight signal interface units are connected to the bus transfer base through slots. In the figure, the host can be an industrial host or an ordinary personal host. The host is equipped with a WINDOWS XP operating system and an upper computer application program; the multi-serial card has eight serial ports, and the multi-serial card 20 is connected to the host through a PCI interface. In the example, the eight-way serial port is an eight-way RS232 signal interface, and obviously it can also be an eight-way RS485 signal interface; the bus...

Abstract

The invention discloses a capacitance touch screen burn test system, comprising a host; the host is connected with a multi-serial port card comprising multiple paths of serial ports; and the multiple paths of serial ports are correspondingly connected with multiple signal interface units. The functions of parallel data communication, program burn and test of the host for the multi-capacitance touch screen are realized by the processing and transmission on the test signal by the host, the multi-serial port card and the signal interface unit, and the capacitance touch screen test system is compatible with the burn and test protocols of various different capacitance screen-driven integrated circuits (IC), a test clamp and the test procedures are simplified, the management is convenient, the efficiency is improved, and the cost is saved. The capacitance touch screen burn test system can be widely applied to the burn test of the capacitance touch screens.

Description

technical field [0001] The invention relates to the field of test circuits or test equipment, in particular to a capacitive touch screen programming test system. Background technique [0002] FPCBA: Flexible Printed Circuit Board + Assembly, a flexible circuit board after the SMT production process, referred to as FPCBA. [0003] CMOS: refers to a complementary MOS integrated circuit composed of complementary metal oxides (PMOS transistors and NMOS transistors). [0004] SCSI: Small Computer System Interface, a small host system interface, an independent processor standard for system-level interfaces between hosts and smart devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). [0005] PCI: A bus standard for connecting electronic host motherboards and external devices. [0006] RS232: A serial transmission interface standard, mainly used for short-distance communication between two points. [0007] RS485: RS485 serial bus standard, using balanced...
