Segment code screen for automobile instrument panel, automobile instrument panel and automobile instrument desk

Abstract

The invention provides a segment code screen for an automobile instrument panel, the automobile instrument panel and an automobile instrument desk. The segment code screen comprises a screen body anda circuit unit. The screen body comprises a first polaroid, a first glass substrate, a first driving ITO layer, a liquid crystal layer, a second driving ITO layer, a second glass substrate, a second polaroid and a static electricity leading-out ITO layer arranged between the first polaroid and the first glass substrate, wherein the first polaroid, the first glass substrate, the first driving ITO layer, the liquid crystal layer, the second driving ITO layer, the second glass substrate and the second polaroid are sequentially stacked. A notch is formed at the edge of the first polaroid; a firstelectrical connection structure is arranged in an area, corresponding to the notch, of the electrostatic export ITO layer; the circuit unit comprises a static electricity leading-out circuit board connected with the grounding terminal of the control circuit board, and the static electricity leading-out circuit board is connected with a first electrical connection structure of the static electricity leading-out ITO layer through a binding process. According to the invention, the electrostatic discharge efficiency on the segment code screen can be improved, and the influence on the display effect in the electrostatic discharge process is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to a segment code screen for an automobile instrument panel, an automobile instrument panel and an automobile instrument panel. Background technique [0002] With the improvement of people's quality of life, the car is no longer a simple means of transportation. The instrument panel on it usually includes a segment code screen. The screen body of the segment code screen includes the first polarizer, the first glass The substrate, the first driving ITO layer (that is, the nano-indium tin metal oxide layer), the liquid crystal layer, the second driving ITO layer, the second glass substrate, and the second polarizer, and the segment code screen often produces Static electricity, in the existing segment code screen, static electricity needs to pass through the first polarizer, the first glass substrate, the first driving ITO layer, the liquid crystal layer, and the second...
