Abstract: A mica water level gauge glass includes a steam tee fitting, a balance pipe, a water tee fitting, a steam connecting pipe, a water connecting pipe, a condensation tank, a longitudinal vertical gauge body, and a mica assembly. The gauge body includes a thermal compensation cavity, a steam-water cavity, an auxiliary heat confluence device, and a horizontal steam cavity. The exit points of the thermal compensation cavity arranged in the gauge body is lower than the point of the steam-water cavity exiting from the gauge body.

Abstract: The invention provides a display device. The display device including: a driving mechanism; a rolling mechanism; and a flexible display, the flexible display is supported by the rolling mechanism, and the driving mechanism drives the rolling mechanism to roll in cycles. The display device of the present invention can realize rotational display, thereby satisfying the diversified demand of users.

Abstract: A bending test device and system for a flexible display device is provided. The bending test device has a bending device. The bending device has a bending shaft, an upper bending plate, and a lower fixing plate. An upper clamping plate is disposed on a surface of the upper bending plate. The upper clamping plate is configured to slide along the surface of the upper bending plate. A lower clamping plate is disposed on a surface of the lower fixing plate. The lower clamping plate is configured to slide along the surface of the lower fixing plate. A first tension measuring element connects to an end of the upper clamping plate. A second tension measuring element connects to an end of the lower clamping plate.
