Description

The colored graph and paper display rod of portable type

The utility model relates to the colored graph and paper display rod of a kind of ight portable type of using in the environment that does not have other artificial light source.

It is 97234927 image-text display that Patent Office of the People's Republic of China discloses a kind of patent No. on January 20th, 1999, this display is made up of barred body, display window, the operating circuit that has single-chip microcomputer and semiconductor laser etc., aforementioned display device is because volume is bigger, need external power supply, be not easy to carry, this display can only be used on fixed buildings or the body of wall, and can only show monochrome facsimile.

The purpose of this utility model provides the colored graph and paper display rod of the portable type ight that is applicable to indoor and outdoor work or recreation that a kind of volume is little, cost is low, easy to use.

For achieving the above object, on barred body, be provided with display window and demonstration synchronously and picture and text and select the dual-purpose hand switch, luminophor in the display window for be arranged in one row, by operating circuit by monolithic processor controlled dichromatic LED group, the negative electrode of this group dichromatic LED is connected with the corresponding I/O mouth of single-chip microcomputer, its anode is by the color grouping, be connected with the color control circuit of forming by transistor respectively, this control circuit links to each other with two I/O mouths in addition of single-chip microcomputer, and demonstration and picture and text select the dual-purpose hand switch to be connected to the INT0 mouth of single-chip microcomputer.

After adopting such scheme,, make that this display bar volume is little, be easy to carry because single-chip microcomputer, operating circuit and the power supply etc. of luminophor and its work of control are all placed in the barred body that has display window; Luminophor adopts two-color diode, and with two transistors as the color gauge tap, control two kinds of colors separately, alternately or the while luminous, can obtain the colored picture and text that three kinds of different colours make up; The data that can have several picture and text in the single-chip microcomputer only need be pressed the hand switch on the barred body continuously, just can arbitrarily carry out picture and text and select conversion, and are easy to use.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be Fig. 1 along A-A to diagrammatic cross-section

Fig. 3 is the utility model working circuit diagram.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model by barred body 1, be positioned at display window 2 on the barred body 1, power switch K, show synchronously and picture and text are selected the dual-purpose hand switch S ₁And place single-chip microcomputer 5 on barred body 1 interior circuit board 7, by forming by the luminophor 4 and the operating circuit of single-chip microcomputer 5 controls, the dichromatic LED group of this luminophor 4 for forming a line, negative electrode of this group dichromatic LED links to each other with the I/O mouth of single-chip microcomputer 5, its anode draw afterwards by color be divided into two groups respectively with the color control circuit in transistor T ₁, T ₂Collector be connected transistor T ₁, T ₂Base stage and in addition two I/O mouths of single-chip microcomputer 5 join, this transistor according to the instruction of single-chip microcomputer 5 can be separately, alternately or conducting simultaneously be redness, green, red green replacing or yellow with the color of controlling shown pattern; Show synchronously and picture and text selection dual-purpose hand switch S ₁Interrupt control mouth INT0 with single-chip microcomputer 5 links to each other, and button once will send external interrupt signal one time, and single-chip microcomputer is waken up from power down mode, enters the picture and text show state, begins to carry out display routine; Preset the data of several picture and text in the described single-chip microcomputer 5, according to the setting of program, button repeatedly will enter corresponding picture and text option program continuously, and this selection has memory and keeps function, until reselect next time.One end of barred body 1 is equipped with movable end cover 3, is built-in with the power supply 6 that two joint 1.5V batteries are formed.

Deposit the pictorial data that weaves in the single-chip microcomputer internal memory, as the synchro switch S that presses on the barred body 1 ₁The time, external interrupt signal wakes single-chip microcomputer up from power down mode, and master routine will start procedure for displaying one time, and pictorial data is sent to each I/O mouth by row successively, until images data have been sent; Unclamp synchro switch S ₁, this moment, the INT0 mouth was rendered as high level, and this high level start-up routine carries graph data until finishing in the other direction.Therefore, brandish barred body about only with hand arm or other motion during use, and alternately press or unclamp synchro switch S ₁, selected picture and text will display by row in display window from left to right or from right to left, because human eye has visual persistence effect, thereby can see a complete reflection.Like this, the utility model can carry out picture and text and show in not having the environment of artificial light sources night, as eye-catching commander such as " parking checking " night traffic of etc.ing and advertisement demonstration, make various toys etc.

Claims (3)

1, the colored graph and paper display rod of a kind of portable type, by barred body, be positioned at display window and switch on the barred body, and place luminophor, single-chip microcomputer and operating circuit in the barred body to form, it is characterized in that luminophor (4) in this display window (2) is for forming a line and by the dichromatic LED group of operating circuit by single-chip microcomputer (5) control, the negative electrode of this group dichromatic LED is connected with the corresponding I/O mouth of single-chip microcomputer (5), its anode is connected with the color control circuit respectively by homochromy grouping; This control circuit links to each other described switch (S with two I/O mouths of single-chip microcomputer (5) ₁) be connected to the INT0 mouth of single-chip microcomputer.
