Problems solved by technology

The text part, scale line, and indication positions of the current car dashboard are light-transmitting areas, and the rest of the area is usually sprayed with black paint with good shading effect, and a light-emitting device is placed behind the dashboard to illuminate the entire dial after power-on. Part of it is opaque. Due to the large color difference between the shading part and the light-transmitting part, the displayed light atmosphere effect is not satisfactory. Drivers stare at the instrument panel for a long time, and their eyes are prone to fatigue

Abstract

The invention relates to an automobile instrument display device based on a segment code screen, in particular to a segment code screen and colored liquid crystal display screen combined display device, belongs to the technical field of automobile instrument display and aims to solve the problems that light shading and transmitting parts of existing automobile instruments have larger color difference and the displayed light atmosphere effect is not satisfied. The segment code screen and colored liquid crystal display screen combined display device comprises a light shading cover, a light shading cylinder, a screen ring, the segment code screen, a colored liquid crystal display screen, a light guiding cover, a PCB (printed circuit board) and a bottom casing, wherein the light shading coverand the screen ring are detachably arranged on the light shading cylinder, an inner groove is formed in the middle of the light guiding cover, the colored liquid crystal display screen is detachably mounted in the inner groove, the segment code screen is larger than the colored liquid crystal display screen and covers the outer side of the colored liquid crystal display screen, the PCB is fixedlymounted on the rear side of the light guiding cover, and the bottom casing is fixedly mounted on the rear side of the light guiding cover. The visual effect is very remarkable, so that an automobile instrument becomes high-end, and the effect of increasing the attractiveness of the automobile instrument with less input can be realized.

Description

technical field [0001] The invention relates to an automobile meter display device based on a segment code screen, which belongs to the technical field of automobile meter display. Background technique [0002] The name of the segment code LCD screen originated when the early liquid crystal display screen began to be used, mainly to replace the LED digital tube (composed of 7 pen segments, used to display numbers 0 to 9), such as calculators, clocks, etc., the display content is uniform For numbers, it is also simpler. Segment type LCD screen, or pen segment type LCD screen, is what LCD users call a certain type of LCD screen, but in the LCD industry, small LCD screen mold opening and small size LCD screen mold opening are generally called pattern type. LCD screens are different from dot-matrix LCD screens, so segment code LCDs are not a strict expression or classification. [0003] The car driver can know the driving speed of the car and the working condition of the engin...
