[0002] With the development of instrument intelligence, human-computer interaction has become an important function of the instrument. The display screen is the bridge of human-computer interaction, and it is indispensable in the use of the detector. In order to improve the anti electromagnetic interference performance of the detector when using the display screen, a smaller display screen is usually used to reduce the area of electromagnetic radiation and electromagnetic acceptance, and a shielding net is used to cover the display screen to reduce the electromagnetic influencing factors of the display screen. However, the user experience is not good when the display screen is small, and the anti electromagnetic interference characteristics are also limited.

[0003] When reducing electromagnetic interference, the area of the display screen is reduced and the electromagnetic shielding net is installed. The defect is that the anti electromagnetic interference performance is limited. Moreover, due to the need of anti electromagnetic interference, the shielding layer is added, the thickness of the display screen is increased, the space is occupied, and after the display screen is reduced, only small size pictures can be displayed, and even only text can be displayed, which affects the user experience and human-computer interaction function.

[0021] Figure 1 The left upper layer is the shielded glass 3, and the lower layer is the display screen body 5. The right side detector panel 1, the conductive sealant 2, the shielded glass 3, the conductive cloth 4, and the display screen body 5 represent the processing of the gap between the detector panel 1 and the display screen body 5. The conductive cloth 4 and the conductive sealant 2 are sequentially covered at the gap between the display screen body 5 and the shielded glass 3. The conductive sealant 2 is coated at the gap between the shielded glass 3 and the detector panel 1, so that the display screen body 5 and the detector panel 1 form a complete shielding structure to reduce the influence of electromagnetic interference.

[0022] The detector panel 1 belongs to the detector shell and is used for fixing the display screen body 5. The conductive sealant 2 is tightly connected with the shielded glass 3 and the conductive cloth 4 to form a conductive whole.

[0024] The shielded glass 3 covers the upper surface of the display screen body 5 and forms a conductive whole with the detector panel 1 to play a shielding role.

[0025] The conductive sealant 2 and the conductive cloth 4 are sequentially filled between the shielded glass 3 and the display screen body 5. The conductive cloth is beneficial to the fixation of the display screen body 5. Under the joint action of the conductive sealant 2 and the conductive cloth 4, the conductive sealant 2, the shielded glass 3, the conductive cloth 4, and the display screen body 5 become a tightly connected conductive whole to play a shielding role to prevent electromagnetic leakage.

[0026] Working principle

[0027] When external electromagnetic interference exists, electromagnetic waves act on the surface of the tightly connected display screen. The electromagnetic waves only act on the surface of the detector shell and cannot enter the internal part of the instrument. The detector can work normally. At the same time, the electromagnetic waves in the internal part of the detector only act on the internal part of the detector and do not produce electromagnetic interference to the external environment.
