Embodiment Construction

[0034] Embodiments of a display device for a construction machine according to the present invention will be described below with reference to the drawings.

[0035] As shown in FIG. 2 , the monitor panel 10 of the present embodiment is installed in a cab 40 of a construction machine. In addition control room 40 such as image 3 A light switch 45 is shown provided. When the indicator 45a of the lighting switch 45 indicates the first switch position 46, the lighting of the display device, the headlights of the construction machine, and the working lights are all turned on. When the indication part 45a of the illumination switch 45 indicates the second switch position 47, the illumination lamp of the display device is turned on and the display device is illuminated. In addition, the headlights and work lights of the construction machine are turned on at this time. When the indicator 45a of the lighting switch 45 instructs the third switch 48, the headlights and work lights of ...

Abstract

To prevent a display screen from being reflected on glass shields, without lowering the visibility of a display portion. The brightness of the display color of either the background portion 31 on a display screen 30 or the background portion 31 of such one of display portions 32 and 33 as occupies the larger area of the lit portion of the display screen 30 is changed according to the control of a control switch 23. If the brightness of the display color of the background portion 31 is lowered (from the 'thin light blue' to the 'thick light blue', for example) at the nighttime, therefore, its reflection on the less around a cabin 40 can be reduced without lowering the luminance of the display screen 30. Alternatively, the saturation or hue of the display color is likewise changed.

Description

technical field [0001] The present invention relates to a device for changing brightness difference, chromaticity difference and hue difference on the screen of a display device installed in a control room of a construction machine. Background technique [0002] A display device is provided in the operating room of the construction machine. The display screen of the display device has a background portion and a display portion. The display part is a bar graph showing the remaining fuel, water temperature, oil temperature, oil pressure, battery voltage, etc., and warning signs indicating abnormalities. Also referred to as a "warning sign" in the narrow sense of the abnormal representation. However, the term "warning sign" here has a broad meaning including manipulation indications such as parking brake indications and warm-up indications, text indications, and the like. The operator can know the internal state of the construction machine and know the abnormality of the con...
