Description
Technical field
The utility model relates to a kind of foreign language teaching device, in particular a kind of foreign language teaching display screen.
Background technology
At present, foreign language teaching is more and more subject to the attention of the head of a family, in school, conventional foreign language teaching mode sets up multi-media classroom, and teacher completes the teaching to student's listening, speaking, reading and writing ability in multi-media classroom, but, the construction cost of multi-media classroom is high, and equipment is fixed.In addition, foreign language teaching focuses on interchange, and therefore, increasing foreign language learner walks out door, holds foreign language exchanging meeting in outdoor, therefore, is badly in need of a kind of teaching demonstration tool being applicable to large-scale outdoor foreign language teaching and teaching of exploitation.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of foreign language teaching display screen being suitable for large-scale outdoor foreign language teaching and teaching.
The utility model is achieved through the following technical solutions:
A kind of foreign language teaching display screen, comprises support 1, LED screen 2, screen protecting film 3 and light adjusting device, wherein:
Described LED screen 2 is P5LED screen 2, adopts 3535 packaged chips;
Described screen protecting film 3 is pasted in LED screen 2, comprise adhesive-layer 31, supporting layer 32 and tempered glass layer 33, described tempered glass layer 33 is in the same size with whole LED screen 2, described supporting layer 32 is interrupted the periphery being located at tempered glass layer 33, and described adhesive-layer 31 covers supporting layer 32 surface;
Described light adjusting device comprises monolithic microcomputer kernel control module and light sensor 4, the output terminal of described light sensor 4 is connected to the signal input part of single-chip microcomputer, and the signal output part of described single-chip microcomputer is connected with the brightness regulation port of LED screen 2 by an adjustable impedance.
Described support 1 is the movable supporting frame 1 supporting LED screen 2.
The utility model has the following advantages compared to existing technology: the utility model provides a kind of foreign language teaching display screen, this foreign language teaching display screen have employed the P5LED screen of high definition, and with light sensor with the use of, can, according to the light intensity automatic regulating lightness of outdoor, foreign language learner be enable more clearly to see screen clearly; Tempered glass layer diaphragm is set simultaneously, makes display screen not cracky in moving process, protection LED screen, the serviceable life of extension device.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of foreign language teaching display screen;
Fig. 2 is the cross-sectional view of screen protecting film;
Fig. 3 is the circuit structure block diagram of light adjusting device.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
A kind of foreign language teaching display screen of the present embodiment, has structure as shown in Figures 1 to 3, comprises LED screen 2, supports the movable supporting frame 1 of LED screen 2, screen protecting film 3 and light adjusting device, wherein:
Described LED screen 2 is P5LED screen 2, adopts 3535 packaged chips;
Described screen protecting film 3 is pasted in LED screen 2, comprise the adhesive-layer 31 set gradually from inside to outside, supporting layer 32 and tempered glass layer 33, described tempered glass layer 33 is in the same size with whole LED screen 2, described supporting layer 32 is interrupted the periphery being located at tempered glass layer 33, and described adhesive-layer 31 covers supporting layer 32 surface; Because supporting layer 32 has thickness, therefore between tempered glass layer 33 and LED screen 2, an air layer is formed, again because supporting layer 32 is for being interrupted arrangement, its discontinuities forms two-way air duct, when this screen protecting film 3 is collided extruding, the air of the air layer between tempered glass layer 33 and LED screen 2 can flow to space outerpace through two-way air duct, then, when collision or extruding force disappear, the air of space outerpace flows back to air layer through two-way air duct again, form cushion space, protection LED screen escapes injury;
Described light adjusting device comprises monolithic microcomputer kernel control module and light sensor 4, described single-chip microcomputer is for be made up of STM32F103 chip and peripheral oscillatory circuit thereof, the output terminal of described light sensor 4 is connected to the signal input part of STM32F103 chip, and the signal output part of described STM32F103 chip is connected with the brightness regulation port of LED screen 2 by an adjustable impedance; The light of described light sensor Real-Time Monitoring external environment condition, and by signal feedback to STM32F103 chip, STM32F103 chip, according to the brightness of the Signal Regulation LED screen of feedback, to adapt to various light environment, reaches best bandwagon effect.
Claims (2)
1. a foreign language teaching display screen, is characterized in that, comprises support (1), LED screen (2), screen protecting film (3) and light adjusting device, wherein:
Described LED screen (2) is P5LED screen (2), adopts 3535 packaged chips;
