[0060] The data conversion unit 204 includes: a digital-to-analog converter, a first end of the digital-to-analog converter is connected to the second end of the operational amplifier 2024, and is used to obtain the initial consumption data of the display chip to be tested, perform digital-to-analog conversion on the initial consumption data, and obtain the operation consumption data of the display chip to be tested.

[0061] The second end of the digital-to-analog converter is connected to the control unit 104 for transmitting the operation consumption data to the control unit 104; the control unit 104 is used to calculate the power consumption of the display chip to be tested based on the operation consumption data.

[0062] Among them, the operational amplifier 2024 is a circuit unit with a very high amplification factor, and is provided with a non-inverting input terminal Vin (+) (also known as a non-inverting input terminal), an inverting input terminal Vin (-) and an output terminal Vout. Generally speaking, commonly used operational amplifiers include general-purpose operational amplifiers (such as μA741, LM358 and LM324, etc.), high-impedance operational amplifiers (such as LF355, CA3130 and CA3140, etc.), low-temperature drift operational amplifiers (such as OP07, OP27, AD508, etc.), high-speed operational amplifiers (such as LM318, μA715, etc.), low-power operational amplifiers (such as TL-022C, TL-060C, etc.), high-voltage and high-power operational amplifiers (such as D41) and programmable control types (such as PGA103A), etc. The operational amplifier used in the utility model can be any type of operational amplifier above, and is not specifically limited here.

[0063] Exemplarily, the control unit 104 outputs a control switching signal to the switching unit 102, controls the switching switch of the switching unit 102 to establish a connection with the power consumption detection module 200, switches the ground pin of the display chip to be tested to ground, and switches the power pin of the display chip to be tested to the sampling resistor 2022 of the power consumption detection module 200, and establishes a connection with the sampling resistor 2022. At this time, the display chip to be tested starts to work normally, the operational amplifier 2024 amplifies the voltage difference across the sampling resistor 2022, and transmits the amplified voltage difference to the data conversion unit 204, and the amplified voltage difference data is the initial consumption data of the display chip to be tested. The data conversion unit 204 includes a digital-to-analog converter, which performs digital-to-analog conversion on the initial consumption data of the display chip to be tested to obtain the operation consumption data of the display chip to be tested.

[0064] The digital-to-analog converter is also connected to the control unit 104, and is used to transmit the operation consumption data of the display chip to be tested to the control unit 104. Optionally, the sampling resistor 2022 uses a milliohm-level resistor, which will not cause a voltage drop to the power supply. That is, the control unit 104 can obtain the path current value of the display chip to be tested by calculating the voltage difference and the resistance value across the sampling resistor 2022. The path current value of the display chip to be tested is calculated multiple times, and the average value of the multiple path current values ​​of the display chip to be tested is taken, and the power consumption of the display chip to be tested is determined based on the average value.

[0065] The control unit 104 can also perform a power short circuit detection on the display chip to be tested according to the path current value of the display chip to be tested, that is, when the path current value of the display chip to be tested is too large and exceeds the preset current threshold, it is determined that the display chip to be tested has a power short circuit. At this time, the control unit 104 can automatically turn off the power circuit of the display chip to be tested and display the power circuit short circuit result on the host computer. Specifically, the control unit 104 can transmit the power consumption result or the power circuit short circuit result of the display chip to be tested to the host computer through the PC bus interface for display and storage.

[0066] In one exemplary embodiment, Figure 3 , which is a connection diagram of the binding detection module 300 .

[0068] The shift register 304 may be a parallel-to-serial shift register.

[0069] Specifically, the control unit 104 outputs a control switching signal to the switching unit 102, controls the switching switch of the switching unit 102 to establish a connection with the binding detection module 300, and controls the power pin of the display chip to be tested to be suspended, and the ground pin of the display chip to be tested is switched to the pull-up resistor. Figure 3As shown in the connection equivalent diagram on the left side of the connection schematic diagram of the binding detection module 300, since there is a diode protection circuit in the pin of the display chip to be tested, if the display chip to be tested is successfully bound, the pull-up signal generated by the pull-up resistor will be connected to the parallel input interface of the shift register through the diode of the above-mentioned diode protection circuit, the binding line and the connecting line 302. At this time, the binding detection and judgment of the display chip to be tested is performed according to the level signal of the parallel input interface connected to the shift register. Specifically, if the level signal of the parallel input interface is high, it means that the display chip to be tested is successfully bound, and if the level signal of the parallel input interface is low, it means that the display chip to be tested fails to bind. Optionally, due to the presence of a parallel-to-serial shift register in the display chip detection device, all detection results can be expressed as serial data, that is, the number of pins of the display chip that can be detected by the display chip detection device is not limited by the SOC and can be any number.
