specific Embodiment approach 1

[0021] Specific implementation mode one: the following combination Figure 1 to Figure 6 Describe this embodiment mode. The signal plate progressively integrated black liquid crystal car combination instrument in this embodiment mode includes a screen ring 1, a pointer 2, a signal plate 3, a bracket 4, a liquid crystal 5, a printed board 6 and a bottom case 7, and the screws 8 The components are assembled together, and the main structure is the same as that of the traditional instrument cluster. The innovation of the present invention lies in the design of the visual transition scheme for the signal sheet and the liquid crystal junction area: on the signal sheet, the edge position of the liquid crystal area is printed with a gradient transition pattern, and the gradient The transition pattern is: print n layers of dots on the edge of the liquid crystal area, from the inside to the outside, the first layer, the second layer...the nth layer, n≥3; the dots on the same layer are eq...

Abstract

The invention discloses a signal sheet progressive integrated black liquid crystal automobile combination instrument, belongs to the field of automobile electronic combination instruments, and aims tosolve the problems of large color contrast difference between a liquid crystal region and two sides and poor full liquid crystal simulation effect of the combination instrument in a power-off and screen-off state. A gradual transition pattern is printed at the edge position of a liquid crystal area on a signal sheet. According to the gradual transition pattern, n layers of dots are printed at theedge of the liquid crystal area, namely a first layer, a second layer... an nth layer from inside to outside, and n is larger than or equal to 3; the dots on the same layer are equal in size and equal in distance; the diameters of the dots from the first layer to the nth layer are gradually increased, and the dots of the adjacent layers are arranged in a crossed mode. The combination instrument is used for color transition between the signal sheet and the liquid crystal, so that colors of the combination instrument tend to be consistent.

Description

technical field [0001] The invention relates to the improvement of a liquid crystal structure sheet of an instrument panel, and belongs to the field of automobile electronic combination instruments. Background technique [0002] There are only three states for the existing car combination instrument, one is a full LCD instrument, which is displayed on a single LCD screen, and the screen is black when the power is off; the second is a traditional combination instrument with a relatively simple layout; the third is It is a trend meter combined with a signal plate and a liquid crystal. At this stage, the development of instruments in the automotive electronics industry is gradually developing towards large screens. Compared with the development of automotive instruments this year and looking forward to the next few years, the future will be the era of full LCD instruments. At present, the main problem encountered in the full LCD instrument project is that the cost of the full ...
