Abstract
The utility model discloses a novel picture and text shadow double-sided display stick, which is characterized in that: a light-emitting diode array passes through a circuit board to realize the double-sided display of picture and text contents; a control circuit is provided with a one-way sensor and a manual control switch; a stick body can be shaken freely without causing pattern disorder, and can emit light when not shaken; and the control circuit is provided with a universal serial bus (USB) interface, so that display contents can be updated at any time. The novel picture and text shadow double-sided display stick has a simple structure, low cost and high practicability.
Description
Technical field
The utility model belongs to technical field of electronic products, and definite saying relates to the shadow rod that one group of light emitting diode is realized the picture and text double-sided display.
Background technology
At present, along with the popularization and application of electronic product, people like coming create atmosphere by brandishing flash rod participating in large-scale party or site of activity, picture and text shadow display bar especially, and that both pictures and texts are excellent again is very popular because of its small volume and less weight.The present hand-held formula picture and text shadow display bar of brandishing generally comprises the clear tubular shell, is installed in light emitting diode (LED) array and driving circuit and control circuit in the barred body inner chamber.Driving circuit and control circuit are generally all formed with single-chip microcomputer and peripheral cell, comprise CPU (central processing unit), graph text information storage unit and timer, the graph text information that shows is stored in the graph text information storage unit with being waited branch, brandish display bar at every turn, under the effect of timer, CPU (central processing unit) is regularly intactly delivered to the graph text information segmentation in the graph text information storage unit demonstration of driving circuit rear drive light emitting diode (LED) array according to brandishing direction in batches successively, utilizes the persistence of vision principle to form complete graph text information.
The defective that existing picture and text shadow display bar exists: a kind of is directionless sensor, needs manually to control (gauge tap) provider when brandishing and shows to information graphic, uses very inconvenient; Though another kind is to be provided with sensor, to establish and have plenty of the bilateral transducer cost than higher and install extremely inconveniently, the components and parts that contain in the product circuit are more, and cost is higher in actual applications, and picture and text only limit to single face and show that the picture and text display effect is bad; Existing in addition picture and text shadow display bar is not rocking barred body without any light, makes display effect relatively more dull, has limited usable range.
The utility model content
The purpose of this utility model with regard to provide a kind of simple to operate, have direction sensor and manually control function can freely brandish and figure disorder, picture and text double-sided display can not occur, can be luminous when not brandishing barred body and the picture and text displaying contents can be with the formula of the brandishing picture and text shadow display bar that advances to upgrade.
The technical solution adopted in the utility model is for achieving the above object: the utility model provides a kind of novel picture and text shadow double-sided display rod, comprises transparent outer cover 1, is installed in power supply 2, light emitting diode matrix 3 and wiring board 4 in the transparent outer cover inner chamber; Described wiring board 4 is provided with driving circuit and control circuit, control circuit comprises CPU (central processing unit) and graph text information storage unit, it is characterized in that: light emitting diode matrix 3 runs through wiring board 4 and is fixedly connected on the two sides of wiring board 4, realizes that picture and text displaying contents two sides shows.
Be provided with unidirectional transducer 5, timing unit and adjustable timer in the control circuit; Interval time between the timing unit record sensor output signal, the timing value of adjustable timer was directly proportional with interval time between the timing unit record sensor output signal; Control circuit is provided with unidirectional transducer 5 and touch-switch 6, do not put in 6 three seconds to control and need unidirectional transducer 5 by pinning touch-switch, and display graphics can not got muddled, light emitting diode matrix 3 can be luminous when not brandishing barred body.
As further setting of the present utility model: also be provided with USB interface 7 in the control circuit, can be connected, upgrade the displaying contents of graph text information storage unit at any time with equipment such as external computer.
The beneficial effects of the utility model are: light emitting diode matrix 3 runs through wiring board 4 and is fixedly connected on the two sides of wiring board 4, and picture and text displaying contents two sides is shown; Owing in control circuit, be provided with unidirectional transducer 5, timing unit and adjustable timer, CPU (central processing unit) is by the interval time of timing unit record between sensor output signal and the timing value of the adjustable timer of corresponding adjustment, the speed of no matter brandishing is fast or slow, CPU (central processing unit) can both and be brandished direction and intactly the graph text information segmentation in the graph text information storage unit be delivered to successively driving circuit rear drive light emitting diode matrix in batches and shown at every turn according to the speed of brandishing of reality, and guarantees can not occur the display graphics disorder; Control circuit is provided with unidirectional transducer and touch-switch, do not put in 3 seconds to control and need unidirectional transducer by pinning touch-switch, and display graphics can not got muddled, light emitting diode matrix 3 can be luminous when not brandishing barred body.
When further in control circuit, being provided with USB interface, can be connected with equipment such as external computer, upgrade the displaying contents of graph text information storage unit at any time.
