Abstract

The invention discloses an integrated button light guide panel and a display device. The button light guide panel is in the shape of "back" with a cavity structure in the center, and the outer edge of the upper surface of the button light guide panel extends perpendicularly to the upper surface to form a Side wall; wherein, a receiving groove for accommodating the hidden end of the control component is formed between the cavity structure and the side wall of the key light guide panel; the display screen can be parallel to and close to the upper surface of the key light guide panel and arranged in the cavity structure. The invention greatly shortens the visual depth, reduces the risk of visual blind spots, makes the visual range wider, and is safer and more reliable.

Description

technical field [0001] The invention relates to the field of airborne display, in particular to an integrated button light guide panel and a display device. Background technique [0002] In the field of airborne display, almost all cockpit display front panels will be designed with button light guide panels, that is, displays equipped with button light guide panels in the cockpit to meet the needs of night flight or night mode operations. Most of the key light guide panels are designed with luminous icons such as marks and characters. At the same time, control components such as buttons, knobs or toggle switches are designed around the key light guide panel to ensure that the pilot can clearly see the operation of the display when flying at night. interface to ensure accurate operation. [0003] However, in the existing display device, when the pilot observes the display screen under a larger viewing angle, there will be a certain visual blind zone, which affects the interp...
