Abstract
A LCD variable information board adopts a display editing communication PC which transmits display data to a communication control unit. After receiving the transmitted display data, the single-chip microcomputer 8051 of the communication control unit transmits the display data address to a shift register in the format of lattice site and transmits the display data to a data latch. After receiving the display data and the gating address, the display controller on the LCD display board then opens designated LCD display points to display stated content. Big lattice LCD display matrix ignores in-between gaps in presentation graphics context, the 8051 single-chip microcomputer controls the LCD display module to display lattice graphics context in a high-speed serial static mode, and the display screen of 10 square meters can complete picture switching within 1 minute. The utility model solves the problem that: a prior outdoor LCD LED big Chinese character display screen can not display clearly under impact of sunlight in the daytime with big power consumption.
Description
Technical field:
The utility model relates to the improvement of road sign, and a kind of liquid crystal display variable information board especially is provided, and belongs to highway mark direction board technical field.
Background technology:
Existing motorway guide planks adopts the LED display mode more, the electric power system complexity, and power consumption is big, the production cost height, and need on-the-spot modulation displaying contents, serviceable life is shorter.
Summary of the invention:
The utility model provides a kind of liquid crystal display variable information board, and it is big and be subjected to daytime sunlight to influence the unclear problem of demonstration out of doors to have solved the power consumption of existing LCD light emitting diode large-size screen monitors Chinese characters display screen.
Technical solution of the present utility model is as follows: seize demonstration communication PC by volume, communication controller, LCD liquid crystal display systems and power pack cost device that lcd controller and LCD liquid crystal board display matrix are formed, wherein: power supply can adopt solar panel and wind-driven generator to charge a battery, it is automatically controlled by accumulator again and the display system power supply, be connected by input end with the letter of communication controller by the PC data bus, send video data to communication controller, data transmit and can finish by RS-232 interface or wireless communication interface mode, single-chip microcomputer 8051 in the communication controller is after receiving the video data that sends, send the video data address to shift register by the I/O interface with the lattice site form again, send video data to data latches simultaneously, display controller on the LCD display board is after receiving video data and gating address, again the LCD display dot of specific bit is opened, shown the content of regulation.
Large tracts of land LCD display matrix has adopted a little bigger liquid crystal display mode, and a plurality of 8*8 LCD panel combine.
Adopt EL luminescent paper technology to do the backlight of LCD, can make the display screen body structure very thin, every square metre of display driver power consumption is less than 100W, and display brightness can be adjusted automatically with the brightness of environment.
Good effect of the present utility model is: the LCD display matrix of a little bigger liquid crystal display mode, its intermediate gap can be ignored in showing picture and text and not remember, Gu many plates display screen of being made up of this liquid crystal display plate just can be made various sizes, not be subjected to general point liquid crystal display size can not break through one square metre restriction.Show that control adopts 8051 Single-chip Controlling LCD MODULE with high speed serialization static mode display dot system of battle formations literary composition, 10 square metres display screen only needs can to finish the picture conversion in about 1 second and shows.It is big and be subjected to daytime sunlight to influence the unclear problem of demonstration out of doors to have solved the power consumption of present LCD light emitting diode large-size screen monitors Chinese characters display screen.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
Embodiment:
According to shown in Figure 1, compile by solar panel and wind-driven generator 4, display screen picture and text and to seize and LCD liquid crystal display systems that Communication Control PC 5, communication controller 3, lcd controller 2 and large tracts of land LCD display matrix 1 are formed constitutes the utility model.Wherein: the power output end of solar panel and wind-driven generator 4 connects accumulator and charges to it, it is automatically controlled by accumulator again and the display system power supply, transmit and to finish by RS-232 interface or wireless communication interface mode by on-the-spot Industrial PC Computer 5 data, send video data to the single-chip microcomputer in the communication controller 3 8051, the DO-D7 of single-chip microcomputer 8051 and AO port connect data latches 6 and address latch 7 respectively, the display data signal that sends, send video data to data latches 6 with the lattice site form, send the video data address to displacement latch 7, the FPDP of address latch 7 is in parallel with the LCD liquid crystal board of each array of lcd controller 2 (adopting the SPLC063A integrated circuit) and LCD display matrix 1 by displacement gate 8, the signal output port of data latches 6 is connected with the LCD liquid crystal board of LCD display matrix 1 respectively by lcd controller 2, lcd controller 2 on the LCD display board is after receiving video data and gating address, again the LCD liquid crystal board of specific bit is opened, shown the content of regulation.
The LCD display board has adopted a little bigger liquid crystal display mode, the liquid crystal board of a plurality of 200mm*200mm is combined to constitute with the form of matrix and is shown giant-screen, the intermediate gap of each liquid crystal board can be ignored in showing picture and text and not remember, therefore, many plates display screen of being made up of this liquid crystal display plate just can be made various sizes, not be subjected to general point liquid crystal display size can not break through one square metre restriction.This device shows that control adopts 8051 Single-chip Controlling LCD MODULE with high speed serialization static mode display dot system of battle formations literary composition, and 10 square metres display screen only needs can to finish the picture conversion in about 1 second and shows.Show that simultaneously graph-text content finishes by the drawing board software design among the WINDOWS of PC, and image, text and data is changed into the serial display structure of LCD display, reach the LCD display module by 8051 Single-chip Controlling then through the converse routine of LCD display controller.Adopt EL luminescent paper technology to do the backlight of LCD, can make the display screen body structure very thin, every square metre of display driver power consumption is less than 100W, and display brightness can be adjusted automatically with the brightness of environment.
