Description

Technical Field

[0001] The utility model relates to the technical field of rail transit passenger information display terminal systems, in particular to a subway display terminal with a full-lamination process. Background Art

[0002] Subway display terminals are generally bonded using frame-sticking technology. However, due to the temperature difference between the inside and outside of the subway car, water vapor in the air may condense on the display screen, forming fog, especially in humid weather or when the air conditioning temperature is not set properly. This situation is more likely to occur; due to the poor sealing performance of the display screen using frame-sticking technology, water and moisture may penetrate into the interior of the display screen, or in a high humidity environment, water molecules in the air are prone to condense on the cooled display screen surface to form fog. Fog will reduce the clarity of the display screen, making it difficult for passengers to clearly see the displayed information, such as route maps, train arrival times, etc. At the same time, the fog layer may enhance the reflection of ambient light, further affecting the visual effect.

[0003] Therefore, we need to provide a subway display terminal with full lamination process. Ensuring that the subway display terminal has good sealing performance and prevents moisture penetration can minimize the impact of fog on the subway display screen and ensure the normal operation of the subway and the safety and comfort of passengers.
