Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In the related art, the power consumption of each control signal in the display module cannot be measured, so that the optimization of the power consumption is difficult to be improved in a targeted manner.
Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.
Example (b):
referring to fig. 1, the control signal power measuring apparatus 100 includes a signal generating unit 101, a parameter collecting unit 102, and a power calculating unit 103. The signal generating unit 101 is configured to generate a control signal according to a control timing sequence, and the signal generating unit 101 includes a plurality of signal output ports for outputting the control signal, where each signal output port is configured to output a control signal to drive the display module under test. The parameter collecting unit 102 is connected to the signal generating unit 101, and the parameter collecting unit 102 is configured to collect power-related parameters of each control signal. The power calculating unit 103 is connected to the parameter collecting unit 102, and is configured to obtain the power-related parameter collected by the parameter collecting unit 102 and determine the power of each control signal according to the power-related parameter and the voltage of the control signal.
The signal generating unit 101 may be a device including, but not limited to, a chip, a controller, etc. capable of generating and outputting a control signal according to a control timing or a circuit capable of implementing a corresponding function. It can be understood that, when the power measurement of the control signal is performed, the signal generating unit 101 on the control signal power measuring apparatus 100 generates the control signal to drive the display module under test, instead of the display module under test or a driving chip dedicated to driving the display module under test on a screen on which the display module under test is disposed. However, in practical applications, the display module under test may also be driven under the cooperation of the driving chip and the signal generating unit 101, for example, the signal generating unit 101 generates a part of the control signals, and the rest of the control signals are still generated by the driving chip (or other units providing the control signals).
As explained before, the signal generating unit 101 may be implemented using a controller, for example, in some embodiments, the control signal power measuring apparatus 100 includes a Field Programmable Gate Array controller 110 (FPGA), and the Field Programmable Gate Array controller 110 is configured as at least one of the signal generating unit 101 and the power calculating unit 103. It is understood that, for the fpga controller 110, it can be configured with more than one function through programming, for example, as shown in fig. 2, the signal generating unit 101 and the power calculating unit 103 are both implemented by one fpga controller 110, and the parameter collecting unit 102 collects the power-related parameter of the control signal output by the fpga controller 110 and transmits the collected result back to the fpga controller 110. Of course, it is understood that the pins of the fpga controller 110 outputting the control signal and the pins connected to the parameter collecting unit 102 to receive the collected power-related parameter may be different, and in this example, the corresponding ports of the pins correspond to the signal output port of the signal generating unit 101 and the port of the power calculating unit 103 obtaining the power-related parameter, respectively. In some embodiments, the signal generating unit 101 further includes a voltage converting unit, which is configured to convert the voltage of the control signal into a predetermined voltage capable of driving the display module under test, so as to ensure that the signal generating unit 101 can generate the control signal enough to normally drive the display module under test, and the predetermined voltage may be, for example, 3V, 5V, or the like.
As shown in fig. 3, the signal generation unit includes a line scanning drive signal generation unit 1011 and a light emission control signal generation unit 1012;

the light emission control signal generation unit 1012 generates respective control signals for driving the light emission control circuit 202 in the display module under test 200 according to the control timing of the light emission control signals.
As a more specific example, the line scan driving signal includes, but is not limited to, three control signals of GSTV (Gate start signal), GCK (Gate Clock, which is a first Gate Clock signal), and GCB (which is a second Gate Clock signal), and the line scan driving signal generating unit 1011 generates the GSTV, GCK, and GCB control signals according to control timings of the three control signals of GSTV, GCK, and GCB, respectively; similarly, the light Emission control signal includes, but is not limited to, three control signals, namely, an Emission Start signal (ESTV), an Emission Clock (ECK) and an Emission Clock (ECB), and the light Emission control signal generation unit 1012 generates the three control signals, namely, the ESTV, the ECK and the ECB according to the control timings of the three control signals, namely, the ESTV, the ECK and the ECB. As shown in fig. 4, a line driving scanning circuit adapted to the line driving signal is illustrated, wherein VH and VL represent the accessed reference high and low voltages respectively, and GO represents the output of the line driving scanning circuit; referring to fig. 5, a control sequence is illustrated. It should be understood that the specific structural design of the line driving scanning circuit, the light emitting control circuit, and other circuits in the tested display module is arbitrary, and this embodiment is not limited thereto, and for circuits with different designs, only the signal generating unit needs to generate the control signal correspondingly; meanwhile, the control timing of each signal may be designed according to actual control requirements, and is not limited to the above example. Actually, when the power measurement is performed by using the control signal power measurement apparatus of this embodiment, the control sequence according to which the signal generation unit is based may be a preset standard control sequence dedicated to power measurement, or may be a control sequence generated according to actual display.

As a more specific example, the parameter acquisition unit includes a current sampling unit configured to sample a current value of the control signal as the power-related parameter, for example, the current sampling unit acquires a current value of at least one control signal among the respective control signals of the row scanning drive signal or the light emission control signal as the power-related parameter of the control signal. For example, the current sampling unit may be, but is not limited to, a current measurement chip, an ammeter, and other components, and when the display module under test is driven, the control signal generated by the signal generation unit is transmitted to the display module under test through the current sampling unit.
In another example, as shown in fig. 6, the parameter collecting unit 102 includes a resistor 1021 and a voltage sampling unit 1022 parallel to the resistor 1021, where one end of each resistor 1021 is connected to one signal output port, and the other end is used for connecting to a corresponding signal receiving port on the display module under test, and the voltage sampling unit 1022 is configured to sample a voltage value at two ends of the resistor 1021 as the power-related parameter. For example, a resistor 1021 may be connected to each signal output port of the signal generating unit 101, and the voltage values at two ends of the resistor 1021 are acquired by one or more voltage sampling units 1022 respectively. The resistance of the resistor 1021 should be known, and for more precise measurement of the power of each control signal, the resistor 1021 may also select a precise resistor with higher precision, and the resistance may be, but is not limited to, 5 Ω, 10 Ω, 15 Ω, 20 Ω, 25 Ω, etc., as long as it is ensured that the voltage value across the resistor 1021 can be accurately obtained.
It is to be understood that the parameter acquisition unit may be at least one including, but not limited to, the above examples.
In some embodiments, the parameter collecting unit includes an analog to digital quantity module, the analog to digital quantity module is configured to convert a value of the power-related parameter into a digital signal, and the power calculating unit is connected to the analog to digital quantity module to obtain the digital signal. For example, the analog-to-digital conversion module may be a 10-bit analog-to-digital conversion module, the value of the power related parameter may be converted into a 10-bit digital signal, and the power calculation unit obtains the digital signal and then obtains the value of the power related parameter according to the digital signal.
In practical applications, the control signal power measuring apparatus may further include a result output unit, where the result output unit may include, but is not limited to, a display or a unit for transmitting data to other devices, and the result output unit displays the measured power of the control signal through the display or sends the measured power to other devices (e.g., an upper computer) for presentation.

The embodiment further provides a control signal power measuring system, as shown in fig. 7, which includes the control signal power measuring apparatus 100 and the display module 200 to be tested of the above example, and a signal receiving port of the display module 200 to be tested is connected to a corresponding signal output port on the signal generating unit 101 through the parameter collecting unit 102.
Another alternative embodiment of the invention:
referring to fig. 8, the control signal power measurement method includes, but is not limited to:

the signal generation unit acquires the control timing of each control signal, for example, directly reads the stored control timing, or receives the control timing from another device or unit.
And S1012, generating a control signal according to a control sequence and a preset voltage.
The predetermined voltage in this embodiment is a voltage actually required by the control signal, and the predetermined voltage may be a range or an accurate value according to the actual circuit of the display module to be tested, and the control signal is generated according to the actual circuit and the voltage required when measuring the power. Each signal output port of the signal generating unit is connected with a corresponding signal receiving port on the display module to be tested, and the control signals are input into a corresponding circuit on the display module to be tested to drive the display module to be tested.
S102, acquiring power related parameters of each control signal when the control signal drives the display module to be detected through a parameter acquisition unit;
for example, the parameter acquiring unit may acquire the power-related parameter continuously according to a predetermined frequency, and may calculate the power of the corresponding control signal in real time. Or collecting the average value of the power-related parameters within a certain time to calculate the average power of the corresponding control signal.

the power calculating unit obtains the power related parameters, which includes actively reading data from the parameter collecting unit, or the parameter collecting unit actively sends the power related parameters to the power calculating unit after collecting the power related parameters.
In this embodiment, the voltage of each control signal is known and set, and in practice, the power of the control signal can be calculated by determining the current of the control signal. For example, the determining, by the power calculating unit, the power of each control signal according to the power-related parameter and the voltage of the control signal may include any one of the following manners:
the parameter acquisition unit comprises a current sampling unit, the power related parameter comprises a current value of the control signal, and the product of the current value and the voltage of the control signal is determined to be the power of the control signal. That is, if the current value of the control signal is obtained by direct sampling, the power of the control signal can be directly calculated;
the parameter acquisition unit comprises a resistor and a voltage sampling unit connected with the resistor in parallel, the power related parameter comprises voltage values at two ends of the resistor, a current value of the control signal is determined according to the voltage values at the two ends of the resistor, and the product of the current value and the voltage of the control signal is determined to be the power of the control signal. That is, the current value of the control signal can be sampled by the resistor and the voltage sampling unit connected in parallel to the resistor, in this way, the current value needs to be calculated by the power calculation unit according to the resistance value of the resistor (the resistance value of the resistor can be written into the power calculation unit in advance before power measurement) and the voltage difference between the two ends of the resistor, and it can be understood that the current value of the control signal is equal to the voltage difference between the two ends of the resistor through which the control signal passes divided by the resistance value of the resistor.
As a specific example, in the present embodiment, a system composed of the control signal power measuring apparatus 100 and the display module 200 to be measured illustrated in fig. 10 is taken as an example to describe the process of measuring the control signal power more specifically.
As above fig. 10, the control signal power measuring apparatus 100 includes the field programmable gate array controller 110, and the field programmable gate array controller 110 includes the row scan driving signal generating unit 1011 and the light emitting control signal generating unit 1012, that is, the field programmable gate array controller 110 can generate the row scan driving signal and the light emitting control signal. As shown in fig. 11, the process of controlling signal power measurement includes:
s201, based on a control sequence, a field programmable gate array controller generates a line scanning driving signal and a light-emitting control signal;
as shown in fig. 10, the line scanning driving signal generating unit 1011 generates three control signals GSTV, GCK and GCB, the signal output ports corresponding to the GSTV, GCK and GCB control signals are connected to the corresponding signal receiving ports on the display module 200 to be tested through the precision resistors R1, R2 and R3, respectively, so as to drive and control the line driving scanning circuit 201 on the display module 200 to be tested, the light emitting control signal generating unit 1012 generates three control signals escv, ECK and ECB, respectively, and the signal output ports corresponding to the control signals escv, ECK and ECB are connected to the corresponding signal receiving ports on the display module 200 to be tested through the precision resistors R4, R5 and R6, respectively, so as to drive and control the light emitting control circuit 202 on the display module 200 to be tested.
S202, a voltage sampling unit collects voltage values at two ends of each precision resistor;
the voltage sampling unit 1022 is connected in parallel with each precision resistor, and samples a voltage value at both ends of each precision resistor, in this example, the sampled voltage value is an analog signal voltage. In this example, the voltage sampling units 1022 include two units, and respectively sample each of the row scanning driving signal and the light emitting control signal, in other examples, sampling of all the control signals may be performed by one voltage sampling unit, or one voltage sampling unit may be separately provided for each control signal.
S203, converting the sampled analog signal voltage into a digital signal by an analog-to-digital conversion module;
for example, the analog-to-digital module 1023 converts the analog signal voltage into a 10-bit digital signal (e.g., 0101010101). As a specific example, the 10-bit digital signal may represent 1024 specific voltage values, the values of the 10-bit digital signal correspond to the voltage values one by one, and the corresponding voltage values may be determined according to the digital signal; for other nbit digital signals, it can represent the voltage value of power n of 2 correspondingly. The conversion of the digital signal can of course also be realized by other rules. In some examples, the voltage sampling unit 1022 and the analog-to-digital conversion module 1023 of the present embodiment may be integrated together, i.e., as one analog-to-digital sampling unit.
S204, the field programmable gate array controller acquires a digital signal which is converted after the sampling of the voltage sampling unit, and performs subtraction processing on the voltage at the two ends of the precision resistor to obtain the voltage difference at the two ends of the precision resistor;
that is, the field programmable gate array controller 110 in this example also implements the functionality of the power computation unit. Taking the ESTV control signal as an example, the voltages at two ends of the precision resistor R1 are respectively V1And V2The voltage difference across the precision resistor R1 is V2-V1
S205, the field programmable gate array controller calculates the current value of a control signal passing through the precision resistor according to the voltage difference between two ends of the precision resistor and the resistance value of the precision resistor;
illustratively, the current value of the ESTV control signal is (V)2-V1)/R1Wherein R is1The resistance of the precision resistor R1 through which the escv control signal passes.
S206, the field programmable gate array controller determines the product of the current value of the control signal and the voltage of the control signal to obtain the power of the control signal.
For example, the power P of the ESTV control signal1Equal to the current value (V) of the ESTV control signal2-V1)/R1Multiplied by the difference V of the high and low levels of the ESTV control signal itselfESTV. That is to say P1=(V2-V1)/R1*VESTV
Similarly, the power of each control signal in the row scanning driving signal and the light emitting control signal can be calculated. In other embodiments, the power of other types of control signals may also be calculated. Therefore, by the control signal power measuring method, the power of each control signal can be calculated, the proportion of the power consumption of each part in the display module to be measured can be accurately determined in some implementation processes, and the targeted improvement of the power consumption in the display module is facilitated.
