Abstract
The utility model discloses a circuit structure for transparent display screen, including the ITO conductive film, the conducting wire has been carved to the ITO conductive film, the conducting wire includes a plurality of tree-like circuits, the trunk portion of tree-like circuit is the straight line, trunk portion is connected with a plurality of branches portion, the circuit of branches portion is "return" shape circuit, and each branch portion all is connected with the LED luminotron; this line structure adopts "the shape circuit to adjust the numerical value that the circuit was adjusted to the degree that the circuit was changed voltage and current to realize the requirement of luminotron constant current constant voltage through the design of arborescent circuit according to the different resistance that is in different positions luminotron through calculating, can guarantee like this that the LED luminotron of different positions can both realize the requirement of constant current constant voltage on same display plane to guarantee the normal use of luminotron.
Description
Technical Field
The utility model relates to a transparent display screen technical field, in particular to circuit structure that transparent display screen all used.
Background
In the modern information society, a display screen transmits information and displays videos and advertisements, which become an essential part of our lives and become necessities of our life and work.
An existing transparent display screen is widely used, and the display screen is transparent when not displaying, and light ray incidence is not influenced. The transparent display screen integrated with the original building is installed, a large part of external wall brightening lamps can be saved, and meanwhile, the transparent display screen is attractive, so that the cost can be saved and the advertising benefit can be achieved.
The conventional transparent display screen generally adopts an ITO conductive film as a conductive material, however, because the ITO conductive film is in a form of a square resistor, namely, the resistance values of a square unit are the same, the voltage and the current of LEDs at different positions are different due to different circuit structures, all LEDs cannot achieve constant voltage and constant current, the display effect of the display screen is poor, and the normal service life of the LEDs is influenced.
SUMMERY OF THE UTILITY MODEL
The problem of the line structure influence display screen display effect in order to solve current transparent display screen, the utility model provides a can provide the line structure of constant voltage constant current.
In order to realize the purpose, the utility model provides a technical scheme is: a circuit structure for a transparent display screen comprises an ITO conductive film, conductive circuits are carved on the ITO conductive film and comprise a plurality of tree-shaped circuits, tree parts of the tree-shaped circuits are straight lines and are connected with a plurality of branch parts, and the circuits of the branch parts are 'return'
And each branch part of the shaped circuit is connected with an LED.
In the above technical solution, the "loop" shaped lines include flat lines and strip lines.
Furthermore, the 'return' shaped lines of the lower half branch parts of the trunk parts are in a long strip shape and are formed by combining two or three 'return' shaped lines together.
On the basis of the technical scheme, the 'loop' shaped line of the branch part of the upper half part of the tree part is flat and consists of two or one 'loop' shaped line which are combined together.
In the technical scheme, each branch is connected with an LED.
In addition, the bottom of the tree line is connected with a controller.
The utility model discloses beneficial effect for prior art is: this line structure adopts "the shape circuit to adjust the numerical value that the circuit was adjusted to the degree that the circuit was changed voltage and current to realize the requirement of luminotron constant current constant voltage through the design of arborescent circuit according to the different resistance that is in different positions luminotron through calculating, can guarantee like this that the LED luminotron of different positions can both realize the requirement of constant current constant voltage on same display plane to guarantee the normal use of luminotron.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and 2: a circuit structure for a transparent display screen comprises an ITO conductive film 1, a circuit is carved on the ITO film 1, the circuit comprises a plurality of tree-shaped circuits 2 and 3, the tree-shaped circuits 2 and 4 are used for illustrating in the embodiment, trunk parts 21 and 31 of the tree-shaped circuits 2 and 3 are straight lines, the trunk parts 21 and 31 are connected with a plurality of branch parts 22 and 32, the circuits of the branch parts 22 and 32 are in a 'loop' shape, specifically, the 'loop' shape comprises a flat strip shape, the 'loop' shape of the lower half part is in a strip shape and consists of two or three 'loop' shapes which are combined together, and the 'loop' shape of the upper half part is in a flat shape and consists of two or one 'loop' shape which are combined together. And each branch part is connected with an LED luminous tube. The bottom of the tree line is connected with a controller.
Since the ITO conductive film is in the form of a sheet resistance, the resistance value in one square unit is the same. The requirements of constant current and constant voltage of the light emitting tubes are met by changing the numerical values of voltage and current according to different resistance values of the light emitting tubes at different positions through calculating the degree of adjusting the circuit by the return-shaped circuit, so that the requirements of constant current and constant voltage of the light emitting tubes can be met by the LED light emitting tubes at different positions on the same display plane, and normal use of the light emitting tubes is guaranteed.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
