[0003] like figure 1 As shown, when using the polarizer attaching equipment to attach the polarizer to the display screen, it is necessary to use the automatic roller 03 on the console 02 to press the aligned polarizer and the display 04, and the distance that the automatic roller 03 rolls It is generally set by the operator. If this distance is not set properly, the automatic roller 03 will crush the components on the integrated circuit board 05, causing damage to the components, and the damaged components or photoresist may be damaged. Adsorbed on the automatic scroll wheel 03, when the automatic scroll wheel 03 rolls back to the display screen 04, it will cause the display screen 04 to be scratched or even broken

The embodiments of the invention provide an alarm circuit, an integrated circuit board and an alarm system and relates to the technical field of electronics. The alarm circuit, the integrated circuit board and the alarm system can reduce damage of polarizer attachment devices to components on integrated circuits and increase qualification rate of display screens. The alarm circuit is composed of a power supply, a buzzer and a switch in a series loop. The switch is arranged inside the integrated circuit board and on a first boundary which connects a display screen, or the switch is arranged in the area between the extending line of the first boundary and the extending line of a second boundary. The second boundary is inside the display screen and connects the integrated circuit board. The alarm circuit is applied to the press-fit of the polarizer attachment devices to a polarizer and the display screen.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an alarm circuit, an integrated circuit board and an alarm system. Background technique [0002] Generally, the display device that can realize the display function is mainly composed of a display screen and an integrated circuit board that controls the work of the display screen. The integrated circuit board can be PCB (Printed Circuit Board, printed circuit board) or FPC (Flexible Printed Circuit board, flexible printed circuit board) board), the integrated circuit board is generally provided with IC (Integrated Circuit, integrated circuit) chips and other components. [0003] Such as figure 1 As shown, when using the polarizer attaching equipment to attach the polarizer to the display screen, it is necessary to use the automatic roller 03 on the console 02 to press the aligned polarizer and the display 04, and the distance that the automatic roller 03 rolls It is general...
