Abstract

The invention discloses a display screen positioning detecting device and method. The display screen positioning detecting device comprises a base (1), a display screen storing mechanism (2) detachably arranged on the base (1) and a pressing block mechanism (4) arranged above the display screen storing mechanism (2). The display screen positioning detecting device further comprises a detecting mechanism which can conduct position collection on the display screen storing mechanism (2) and a display screen (3). Through the design, the parallelism and the center contact ratio of the display screen storing mechanism and the display screen which are finally well assembled are effectively monitored and determined, the product quality is greatly improved, and the reworking possibility is decreased; and the operation method is simple, reinforcing and detaching are convenient, and cost is low.

Description

technical field [0001] The invention relates to the detection field of military airborne flat display screens, in particular to a display screen positioning detection device and a display screen positioning detection method. Background technique [0002] In the field of military airborne flat-panel display screens, high-resolution, high-brightness, high-contrast, light-weight, and long-life display image sources are the focus of current armament needs. Traditional flat screens generally use CRT as the image source. Because it is a vacuum device, its anti-vibration performance and reliability are poor, and at the same time it requires high-voltage drive, which makes the system complex, susceptible to interference, single image, heavy weight, and lifespan during operation. Therefore, LCD digital image sources with reliable performance, stable performance and finer image processing are gradually replacing CRT image sources. Therefore, the liquid crystal module can be used as t...
