With the continuous development of display screen technology, the integration level of display screen is increasingly higher. In order to reduce the risk of supply chain to parts of display screens and the consideration of corresponding cost control, usually, manufacturers who assemble display screens choose multiple suppliers to supply some important parts, while the design and process of the parts from different suppliers may be different, which makes brand dichotomization a restrictive factor. For example, Drive ICs (DIC's) and Power Management ICs (PMIC's) in display screens may be in different sizes and software drivers due to the design, process and other factors of different manufacturers, which easily leads to incompatibility between the power management ICs and the drive ICs produced by different manufacturers.

Referring toFIG.1, in view of this, the present application provides a display module10that includes a drive IC11and a power management IC12, and the power management IC12includes a first identification pin121, and the first identification pin121is connected to the drive IC11.

In a case where the power management IC12is turned on, the power management IC12transmits identification information to the drive IC11through the first identification pin121so that the drive IC11identifies the power management IC12and is paired with the power management IC12.

In the display module10of the present application, the power management IC12is connected to the drive IC11through the first identification pin121, so that when the power management IC12is paired with the drive IC11, corresponding identification information can be transmitted to the drive IC11through the first identification pin121, and the drive IC11can be paired with the drive IC11according to the identification information. In this way, compatibility between the drive IC11and the power management IC12produced by different manufacturers is achieved, reducing the risk of the supply chain and saving the cost.

The display module10may be displayed using an Active-matrix Organic Light-emitting Diode (AMOLED) panel. The power management IC12is electrically connected to the active-matrix organic light-emitting diode panel through the drive IC11. The power management IC12is used to supply power to the active-matrix organic light-emitting diode panel, and the drive IC11is used to drive the active-matrix organic light emitting diode panel to display. Displaying of the active-matrix organic light emitting diode panel of the display module10can achieve autonomous light emitting, can achieve customized driving for pixel points, can achieve display function without backlight, and has the characteristics of low energy consumption, wide viewing angle, high refresh rate, thin size and the like.

It should be noted that both the drive IC11and the power management IC12may be Integrated Circuit (IC) ICs, and the drive IC11may be electrically connected to the power management IC12by bonding pin. The identification information refers to identity information used to characterize the type or brand of the power management IC. Each type of power management IC12or each brand of power management IC12includes corresponding identification information, and the drive IC11can identify the type, brand or the like of the power management IC12based on the identification information.

Specifically, the power management IC12includes a first identification pin121, and the drive IC11includes a second identification pin112. When the power management IC12is assembled with the drive IC11, the first identification pin121is connected to the second identification pin112. The power management IC12includes corresponding identification information. When the power management IC12is activated, the identification information is transmitted to the second identification pin112through the first identification pin121, so that the drive IC11can match the power management IC12according to the identification information. In this way, incompatibility of the drive IC11with the power management IC12is avoided.

It should be noted that the identification information may be recorded by the manufacturer when the power management IC12is designed or manufactured. Referring toFIG.2, the identification information may be a pulse signal, and a quantity of pulses or a width of pulses in the identification information of the drive IC11of different types or brands are different. The drive IC12can determine the type or brand of the power management IC12based on the quantity and the width of pulses in the pulse signal. In the present application, the drive IC11can determine the type or brand of the power management IC12connected thereto based on the quantity of pulses in the pulse signal. For example, in some examples, a power management IC A includes identification information1in which the quantity of pulses is 5, and a power management IC B includes identification information2in which the quantity of pulses is 3. If the power management IC A is connected to the drive IC11, the drive IC11can identify the power management IC A according to the quantity of pulses in the identification information.

In some implementations, the drive IC11includes an enable pin111connected to the power management IC12, the drive IC11transmits an enable signal to the power management IC12through the enable pin111to turn on the power management IC12.

Thus, the drive IC11can transmit the enable signal to the power management IC12through the enable pin111, and the power management IC12can be turned on when receiving the enable signal, so that the identification signal can be transmitted to the second identification pin112through the first identification pin121, so that the drive IC11can be matched with the power management IC12.

In some implementations, the drive IC11includes a plurality of storage registers113corresponding to a plurality of power management ICs12, respectively, each of the storage registers113stores a Look Up Table (LUT) paired with the corresponding power management IC12.

Specifically, each power management IC12includes an LUT. It will be understood that LUTs in power management ICs12of different manufacturers may differ. In order for the drive IC11to be compatible with the power management ICs12, an LUT of the drive IC11must be able to match an LUT of any power management IC12. Thus the drive IC11is provided with a plurality of storage registers,113each of which stores an LUT paired with an LUT of a corresponding power management IC12. Therefore, in a process of pairing the drive IC11with the power management IC12, the drive IC11can select the LUT in the corresponding storage register113to pair with the LUT of the power management IC12after identifying the power management IC12according to the identification information, thereby ensuring compatibility between the drive IC11and different power management ICs12.

In some implementations, the drive IC11further includes a control signal transmitting pin114connected to the power management IC12, and the drive IC11generates a control signal (Swire signal) according to the identification information of the power management IC12and transmits the control signal to the power management IC12through the control signal transmitting pin114.

Specifically the power management IC12further includes a corresponding control signal receiving pin122connected to the control signal transmitting pin114. After the drive IC11receives the identification signal of the power management IC12and is paired with the power management IC12, the LUT of the drive IC11can generate a control signal according to the identification signal, and the control signal transmitting pin114transmits the control signal to the control signal receiving pin122, so that the power management IC12can execute corresponding operations according to the control signal.

In some implementations, the power management IC12further includes a plurality of power supply pins123, and the power management IC12determines a voltage of each power supply pin123according to the control signal and supplies power to the drive IC11through the plurality of power supply pins123.

Referring toFIG.3, it should be noted that the control signal includes a plurality of successive pulse signals, each of which includes a predetermined quantity of pulses. The plurality of pulse signals corresponds to a plurality of power supply pins123, respectively, and each pulse signal controls an output voltage of a corresponding power supply pin123. For example, in some examples, the control signal includes three successive pulse signals, namely a pulse signal A, a pulse signal B, and a pulse signal C. The power management IC12includes a power supply pin a, a power supply pin b and a power supply pin c, wherein, the pulse signal A corresponds to the power supply pin a for controlling an output voltage of the power supply pin a, the pulse signal B corresponds to the power supply pin b for controlling an output voltage of the power supply pin b, and the pulse signal C corresponds to the power supply pin c for controlling an output voltage of the power supply pin c. It can be understood that the power management IC12includes a plurality of power supply pins123which are connected to the drive IC11since type, quantity and magnitude of voltages required by different active-matrix organic light emitting diode panels may differ. The specific quantity of the power supply pins123is not restrictive. For example, the quantity of the power supply pins123may be 2, 3, 5, 6 or even more.

Referring toFIG.4, specifically, the LUT in each power management IC12includes a mapping relationship between the quantity of pulses and the output voltage of the power supply pin123. For example, refer toFIGS.3and4together. In some examples, if the quantity of pulses of three successive pulse signals in the control signal is 5, 6 and 7, respectively, the output voltages of three power supply pins123in the LUT of the voltage management IC are −5.0 V, −4.9 V and −4.8 V, respectively. When the power management IC12receives the control signal, the power management IC12can adjust the voltage of the corresponding power supply pin123to match the voltage corresponding to the quantity of pulses in the LUT according to the quantity of pulses in each pulse signal, so that the power supply pin123supplies power to the drive IC11with the adjusted output voltage.

Referring toFIG.5, the present application also provides a control method for controlling the pairing of the drive IC11and the power management IC12. The control method includes acts S12to S16.

In the control method, the control apparatus200, the electronic device100and the computer readable storage medium40in these implementations, the power management IC12is activated by controlling the drive IC11to transmit an enable signal to the power management IC12, the power management IC12can transmit an identification signal to the drive IC11after activated, so that the drive IC11is paired with the power management IC12according to the identification signal, and controls the drive IC11to transmit a corresponding control signal according to the identification signal, so that the power management IC12supplies power to the drive IC11. In this way, the drive IC11and the power management IC12are paired, so that the drive IC11and the power management IC12work normally, the incompatibility between the power management IC12and the drive IC11produced by different manufacturers is avoided, the risk of the supply chain is reduced, and the cost is saved.
