The invention can ensure that the wiring of the same printed circuit board corresponding to two low-voltage differential signal interfaces can be realized; the variety of the printed circuit board is reduced; and the sharing of the printed circuit board is enhanced.
Description
Technical field
The present invention relates to a kind of method that improves display quality, particularly a kind of method that improves the printed circuit boards of monitor sharing.
Background technology
Now the low-voltage differential signal interface of display pannel manufacturer mainly is divided into two kinds of single channel and binary channels, and the interface pattern is identical, just the definition difference of each pin.Therefore printed circuit board (PCB) need be thought of as the display pannel of these two kinds of different size interfaces when design, carries out wires design respectively, and printed circuit board (PCB) can not be shared like this, to having increased burden in the production management, also increased cost of development.
For example: produce 19 cun displays of a certain model, a kind of main circuit board design, but because two display pannel manufacturer supplies of material are arranged, their interface pattern specification difference, will change the circuit of display pannel interface on the mainboard like this, thereby with respectively corresponding these the two kinds of display pannels of two kinds of mainboards, increased the kind and the cost of printed circuit board (PCB), also made to become complicated in production management.
In order to improve the quality of display, make its packaging technology, more reasonable structural designization, continually develop the novel product of efficient energy-saving more, improve market share, become one of new problem that this field technology personnel are badly in need of solving.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of technology simple, the density height, dependable performance, improve product quality, improve the method for printed circuit boards of monitor sharing, to improve the utilization factor of printed circuit board (PCB), reduce system cost, reach the purpose of simplifying circuit design, enhancing productivity, reduce production costs.
The technical solution adopted in the present invention is for achieving the above object:
A kind of method that improves the printed circuit boards of monitor sharing, the concrete implementation step that it is characterized in that this method is as follows: the P.e.c. board chip makes single channel low-voltage differential signal interface and binary channels low-voltage differential signal interface be consistent at printed circuit board wiring under the prerequisite of the single channel/binary channels pin definitions of low-voltage differential signal interface; The gate that a part is provided with by chip internal is realized picture signal/clock signal/ground/unsettled carrying out four conversion; Can not then add Zero-ohm resistor and carry out gating by another part of chip internal gating realization by the outside; When using single channel, resistance R 2, R3, R4, R5, R6 welding, resistance R 1 is not welded, and is off state; When using binary channels, have only resistance R 1 welding, resistance R 2, R3, R4, R5, R6 do not weld, and are off state.
The present invention is provided with gate in each pin inside respectively, is single channel or binary channels according to the low-voltage differential signal that uses, and provides information by control signal, the corresponding signal of gate output.
The invention has the beneficial effects as follows: simplified structure of the present invention, simple to operate, realize that same printed circuit board wiring can corresponding two kinds of low-voltage differential signal interfaces, reduced the kind of printed circuit board (PCB), improved its sharing, helped management, efficient energy-saving reduces cost.Effectively enhance productivity, improve overall quality, simplify technology, guarantee the consistance of machine product assembling; And be applicable to large-scale production.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, details are as follows for feature:
At first, illustrate that the circuit chip concrete structure that existing display comprises forms and be connected, as shown in Figure 1 and Figure 2, single channel is connected with the binary channels circuit interface.
Existing display product circuit is divided into two ingredients, under the prerequisite of low-voltage differential signal interface (single channel/binary channels) pin definitions that does not change display pannel manufacturer, make single channel low-voltage differential signal interface on printed circuit board wiring, reach consistent with binary channels low-voltage differential signal interface, so just need chip internal design diversification.
As Fig. 3, shown in Figure 5, the gate that the present invention is provided with by chip internal is realized picture signal/clock signal/ground/unsettled, four conversion, a part can not only realize by the chip internal gating, also add Zero-ohm resistor and carry out gating by the outside, represent 0ohm resistance as the resistance that is provided with among Fig. 3, can select whether to weld according to the distinct interface that uses.
When using single channel, resistance R 2, R3, R4, R5, R6 welding, resistance R 1 is not welded, and is off state.
When using binary channels, have only resistance R 1 welding, resistance R 2, R3, R4, R5, R6 do not weld, and are off state.
Illustrate mainly below chip internal is how to realize the gating design:
During the design of IC at present is that each pin signal is directly exported (as Fig. 4), and design of the present invention is gate (as Fig. 5) to be set to each pin inside, low-voltage differential signal according to current use is single channel or binary channels, provide information by control signal, the corresponding signal of gate output.
Above-mentioned detailed description of the method for this raising printed circuit boards of monitor sharing being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
