Embodiment Construction

[0016] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0017] Such as figure 1 , figure 2 and image 3 As shown, in some demonstrative embodiments, a low-emission display is disclosed, including: a front panel, a shielding glass, a glass bead, a liquid crystal display, a main control circuit board, a key device, and a rear case.

[0018] Wherein, the four sides of the shielding glass are respectively fixed by a glass bead, and the shielding glass is fixed at the center of the rear end face of the front panel; part of the front face of each glass bead is bonded to the front panel, and the...

Abstract

The invention provides a low-leakage display. The low-leakage display comprises a front panel, shielding glass and a glass compression bar for fixing the shielding glass on the rear end face of the front panel, wherein one part of the front end face of the glass compression bar is fitted with the front panel, while the other part of the front end face of the glass compression bar is fitted with the shielding glass; a first conductive gasket is arranged between the fitted surfaces of the glass compression bar and the front panel and used for reducing a gap between the two fitted surfaces. The low-leakage display has the advantages that the connection gap between the components associated with the display is sealed by the conductive gasket so that electromagnetic information emitted by a liquid crystal display screen cannot be transmitted to the outside via the gap and the electromagnetic information is shielded, and therefore, the problem of electromagnetic information leakage is effectively solved, the risk that the information is intercepted and captured is reduced and the information of the display is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of low emission, in particular to a low emission display. Background technique [0002] The vast majority of monitors in the country’s secret-related fields are ordinary computer monitors. This type of monitor not only has poor reliability, but also emits strong electromagnetic radiation. Its electromagnetic radiation emissions are easy to be detected and intercepted, and confidential information can be obtained through signal analysis. National security poses a great threat. [0003] Low emission performance (to prevent electromagnetic leakage), according to the national information security standards, it is divided into three levels: A, B, and C, of ​​which level C is the highest level. At present, the low emission displays on the market generally only reach level A and level B And low-emission displays above B level are still in key research projects; the low-emission performance of current low-emission ...
