Abstract

The invention discloses an alarm display device of a liquid crystal display (LCD) screen, and the device consists of an LCD display module, a processor module and a discrete magnitude acquisition module; the discrete magnitude acquisition module is used for acquiring discrete signals and bus signals from an airplane; the processor module is used for outputting a control signal to the LCD display module according to the discrete signal of the discrete magnitude acquisition module and a bus signal; and the LCD display module is used for displaying corresponding prompt level, attention level or warning level information and displaying corresponding colors according to the signal level. The invention has the advantages that the defect of the light-emitting block is overcome, the brightness consistency effect of the alarm display device is better, the contrast ratio is improved, and the technical change efficiency of the alarm display device is greatly improved.

Description

technical field [0001] The present invention relates to an airborne warning, in particular, a warning display device of an LCD display screen. Background technique [0002] The alarm display device is a product with alarm signal display function. [0003] In the past, the common display method of the alarm display device was to embed the signal board on the aluminum panel, and to etch the corresponding signal name on the signal board, using the light-emitting block behind the signal board to provide a light source, and the light through the signal board to display the corresponding signal. The shortcomings of the existing light-emitting block's own characteristics restrict product development, and there are mainly the following deficiencies: 1. In terms of light performance: due to the difference in the light-emitting curves of light-emitting blocks of different colors, the brightness consistency effect is not good, and when the light is emitted When the block voltage is ne...
