The following are multiple implementation examples to illustrate the technical features of this invention, but the technical features of this novel invention are not limited to the multiple implementation examples listed.

FIG1 is a schematic diagram of a three-dimensional structure of a resistance measuring device with an enlarged display according to an embodiment of the present invention. Referring to FIG1, the resistance measuring device with an enlarged display according to an embodiment of the present invention includes a housing 20. The housing 20 is, for example, a six-sided box-shaped structure having an upper surface 30 and a lower surface 32. In fact, the shape of the housing 20 is not limited to the six-sided box structure. The upper surface 30 is on the outside of the housing 20, and the circuit module 16 is disposed inside the housing 20, for example, on the lower surface 32 of the housing 20. The upper surface 30 of the housing 20 is, for example, provided with a keyboard 14, a test port 18, and a support column 12.

The test port 18 can be electrically connected to an electronic component to be tested, such as the resistor 17 to be tested. The analog resistor 10 is arranged on the support column 12, and the support column 12 can mechanically support the analog resistor 10. The support column 12 is, for example, a tubular structure. In addition to supporting the analog resistor 10, it can also allow the connection wire set 34 to pass through, so that the analog resistor 10 is electrically connected to the circuit module 16, so that the circuit module 16 controls the analog resistor 10. The analog resistor 10 includes, for example, a screen 22 and a plurality of light-emitting elements 10a~10d. These plurality of light-emitting elements 10a~10d constitute a light-emitting pattern.

FIG3 is a schematic diagram of the structure of an analog resistor of a resistance measuring device according to an embodiment of the present invention. Please also refer to FIG3 for the portion of the analog resistor 10. According to an embodiment of the present invention, the analog resistor 10 includes a plurality of light-emitting elements 10a~10d, and four light-emitting elements 10a~10d are activated to emit light, and the actual number of light-emitting elements 10a~10d is determined according to actual manufacturing needs. The shape structure of the analog resistor 10 simulates the geometric structure of the resistor to be measured 17, such as a column. The resistor to be measured 17 is, for example, a resistor with four color rings, and these four color rings are traditionally used to indicate its resistance value. However, the light-emitting elements 10a~10d are not limited to being ring-shaped. Thus, in the embodiment corresponding to the resistor 17 to be tested, four light-emitting elements 10a~10d among the multiple light-emitting elements are activated to emit corresponding colored lights, and in combination with the resistance value measured by the resistor 17 to be tested, multiple light-emitting rings are formed to form a light-emitting pattern in combination with the resistance value.

That is, the multiple light-emitting elements 10a~10d of the analog resistor 10 are controlled by the circuit module 16 to emit variable light patterns to display the resistance value. Here, the circuit module 16 also measures the resistance value of the resistor to be tested 17 through the test port 18. It can be understood that different resistors to be tested 17 may have different resistance values, so the multiple light-emitting elements 10a~10d will also cooperate to form different corresponding light-emitting patterns.

The analog resistor 10 may also include a screen 22. As for the connection circuit, the screen 22 and the analog resistor 10 line are electrically connected to the circuit module 16 through the supporting pillar 12 and the connecting wire set 34. Here, the screen 22 can display the resistance value measured by the resistor 17 to be tested, that is, the resistance value of the luminous pattern, in digital form. However, it is explained here that the screen 22 can also display the data input by the keyboard 14.

According to one embodiment, a keyboard 14 and a test port 18 may be provided on the upper surface 30 of the housing 20, which are connected to the circuit module 16 by, for example, a connection line set 34, to perform control operations and corresponding operations of data input by the keyboard 14. Here, for example, when there is no measurement of the resistor 17 to be measured, for example, based on the need for learning, the user may input a resistance value through the keyboard 14, so that the light-emitting elements 10a~10d of the analog resistor 10 may emit light accordingly. That is, the screen 22 may display the resistance value measured by the test port 18, and may also display the content input by the keyboard 14.

The following describes the circuit architecture of the novel resistance measuring device according to an embodiment. FIG. 2 is a schematic diagram of the circuit architecture of the resistance measuring device with an enlarged display corresponding to FIG. 1 according to an embodiment of the novel invention. Referring to FIG. 2 , the communication between the circuit module 16 and the keyboard 14, the test port 18, the screen 22, and the multiple light-emitting elements 10a, 10b, 10c, 10d of the analog resistor 10 is respectively connected through multiple connection lines 34 for two-way communication. The value input from the keyboard 14 is judged by the circuit module 16 and a signal is sent to the analog resistor 10 to control the light-emitting elements 10a~10d to emit light, and a signal is also sent to the screen 22 to display the input value. During the measurement operation, the test port 18 can be connected to an electronic component, such as the resistor 17 to be tested, and the resistance value read is sent to the screen 22 through the circuit module 16, and a portion of the light-emitting elements 10a~10d of the multiple light-emitting elements of the analog resistor 10 is controlled to emit corresponding color light, such as red light, blue light, green light or black light. The individual light-emitting elements 10a~10d are composed of red (R), green (G) and blue (B) light-emitting diodes (LEDs), and the color is controlled by the RGB three-color color adjustment value.

As for the control mechanism of the circuit module 16, as can be understood by conventional techniques in the art, for example, it can be composed of at least one chip, including a chip that can be programmed. The circuit module 16 performs two-way signal communication with the connected components via a plurality of connection lines 34, thereby achieving the required control. Under conventional techniques in the art, the control architecture mechanism of the circuit module 16 can be achieved as needed, and will not be described in detail here.
