CROSS-REFERENCE TO RELATED APPLICATION

The disclosure claims the priority benefit of Taiwan disclosure Ser. No. 111125025, filed on Jul. 4, 2022. The entirety of the above-mentioned patent disclosure is hereby incorporated by reference herein and made a part of the specification.

BACKGROUND OF THE INVENTION

Field of the Invention

The disclosure relates to an electronic device which has a universal motherboard and selects a panel power management module according to a type of a display panel.

Description of the Related Art

There are various existing notebook computer screens. At present, in-plane-switching (IPS) panels and organic light-emitting diode (OLED) panels are commonly used, and have their own advantages. In order to adapt to different usage scenarios, these two types of panels are used as the notebook computer screens. However, such a design usually requires different motherboards corresponding to different types of panels, because IPS panel and OLED panel are completely different display screens.

The IPS panel is made of an inorganic material and includes two parallel glass substrates, with transistors placed below. The IPS generates colors through the interaction between backlighting and filters of the glass substrates. The OLED panel is made of an organic material and includes organic light-emitting diodes, to emit light through a voltage action of an organic coating and a glass substrate. The two types of panels have completely different structures. The biggest difference is that the OLED panel requires a power management circuit and a peripheral signal. Therefore, the motherboard suitable for the OLED panel has a built-in power management integrated circuit (PMIC) design, and the motherboard suitable for the IPS panel does not need this design. Therefore, different types of panels need to have respective motherboard designs.

BRIEF SUMMARY OF THE INVENTION

According to an aspect of this disclosure, an electronic device is provided. The electronic device includes a display panel, a transmission line, and a universal motherboard. The display panel is a first type display panel or a second type display panel. The transmission line is a first transmission line or a second transmission line. The universal motherboard is connected to the first type display panel through the first transmission line, or connected to the second type display panel through the second transmission line. The electronic device further includes a panel power management module, and when the display panel is the first type display panel, the panel power management module is connected to the universal motherboard and the first type display panel through the first transmission line, so that the panel power management module provides power management required for the first type display panel according to the universal motherboard.

To sum up, the electronic device in the disclosure uses a universal motherboard to match different transmission lines without replacing the motherboard, so that the same motherboard is compatible with display panels of two different architectures. In this way, an area of the motherboard is optimized. In addition, with an independent design of the panel power management module, the motherboard is applicable to a wider range. Therefore, the area of the motherboard has higher utilization, and subsequently designed models are also allowed to share the panel power management module, so that different models have better commonality.

However, the preferred embodiments are only described as examples and are not intended to limit the protection scope of the disclosure. In addition, some elements or structures may be omitted in the drawings in the embodiments, to clearly show technical features of the disclosure. Throughout the drawings, the same reference numbers will be used to represent the same or similar elements. It needs be understood that although the terms “first”, “second”, and the like are used herein to describe various elements, components, circuits, or functions, these elements, components, circuits, and/or functions should not be limited by these terms. The terms are only used to distinguish one element, component, circuit or function from another element, component, circuit or function.

Referring toFIG.1andFIG.2together, an electronic device10includes a display panel12, a transmission line14, a universal motherboard16, a lens module18, and an optional panel power management module (that is, PMIC)20. In the electronic device10, the display panel12is one of a first type display panel121or a second type display panel122. The transmission line14is one of a first transmission line141or a second transmission line142. The universal motherboard16is connected to the first type display panel121through the first transmission line141, or connected to the second type display panel122through the second transmission line142. The lens module18is connected to the universal motherboard16through the first transmission line141or the second transmission line142. When the display panel12is the first type display panel121, the electronic device10uses the panel power management module20. The panel power management module20is connected to the universal motherboard16and the first type display panel121through the first transmission line141, so that the panel power management module20provides power management required for the first type display panel121according to the universal motherboard16.

In an embodiment, the electronic device10is a notebook computer, or other electronic devices having a display panel, but the disclosure is not limited thereto.

Because the first type display panel121is a display panel12that requires power management provided by the panel power management module20, in an embodiment, the first type display panel121is an organic light-emitting diode (OLED) panel. As shown inFIG.1andFIG.3, the electronic device10includes the first type display panel121, the first transmission line141, the universal motherboard16, the lens module18, and the panel power management module20. The universal motherboard16is connected to the first type display panel121, the lens module18, and the panel power management module20through the first transmission line141, and the panel power management module20is also connected to the first type display panel121through the first transmission line141. The first transmission line141is an embedded display port (EDP) transmission line, and the universal motherboard16is provided with an embedded display port connector161correspondingly, so that the first transmission line141is connected to the embedded display port connector161, and then electrically connected to the universal motherboard16through the embedded display port connector161. Based on this, the panel power management module20provides power management required for the first type display panel121according to the universal motherboard16, so that the first type display panel121(the organic light-emitting diode panel) runs normally.

In an embodiment, since the panel power management module20is an independent module and a non-fixed mobile device, the panel power management module is mounted at any vacant position in the electronic device10. In an embodiment, the panel power management module20is mounted in a frame of the first type display panel121.

Since the second type display panel122is a display panel12that does not require the panel power management module20, in an embodiment, the second type display panel122is an in-plane-switching (IPS) liquid crystal panel. As shown inFIG.2andFIG.4, the electronic device10includes the second type display panel122, the second transmission line142, the universal motherboard16, and the lens module18. The universal motherboard16is connected to the second type display panel122and the lens module18through the second transmission line142. The second transmission line142is an embedded display port (EDP) transmission line, and the universal motherboard16is provided with an embedded display port connector161correspondingly, so that the second transmission line142is connected to the embedded display port connector161, and then electrically connected to the universal motherboard16through the embedded display port connector161. Based on this, in order to make the second type display panel122(the in-plane-switching liquid crystal panel) run normally, it is only necessary to connect the universal motherboard16to the second type display panel122.

In an embodiment, referring toFIG.1andFIG.3together, the first transmission line141is the embedded display port transmission line, and further includes a power cable and a signal cable, so that the first transmission line141should allow a corresponding current and signal speed. Therefore, the universal motherboard16transmits power and signals to the first type display panel121, the lens module18, and the panel power management module20through the first transmission line141, and the panel power management module20transmits power and signals to the first type display panel121through the first transmission line141. Similarly, referring toFIG.2andFIG.4together, the second transmission line142is an embedded display port transmission line, and further includes a power cable and a signal cable, so that the second transmission line142allows a corresponding current and signal speed. Therefore, the universal motherboard16transmits power and signals to the second type display panel122and the lens module18through the second transmission line142. The power cable usually uses American Wire Gauge (AWG) Teflon wire (Teflon wire), and the signal cable usually uses American Wire Gauge (AWG) coaxial wire (Coaxial wire).

Furthermore, as shown inFIG.1andFIG.2, in order to make the same universal motherboard16compatible with the first type display panel121and the second type display panel122of two completely different architectures, the embedded display port connector161on the universal motherboard16is designed with a common circuit and multi-functional pin assignment. Therefore, for the pin assignment of the embedded display port connector161, refer to Table 1 below.

Therefore, as shown inFIG.1andFIG.2, in the disclosure, the first transmission line141is used with the independent panel power management module20for the first type display panel121(the organic light-emitting diode panel), and the second transmission line142is used for the second type display panel122(the in-plane-switching liquid crystal panel), without changing the universal motherboard16. The same universal motherboard16is shared, and the panel power management module20does not need to be arranged on the universal motherboard16, to save space. If the second type display panel122(the in-plane-switching liquid crystal panel) is used, the panel power management module20is further omitted.

To sum up, the electronic device in the disclosure uses a universal motherboard to match different transmission lines without replacing the motherboard, so that the same motherboard is compatible with display panels of two different architectures. In this way, an area of the motherboard is optimized. In addition, with an independent design of the panel power management module, the motherboard is applicable to a wider range. Therefore, in this case, the area of the motherboard has higher utilization, and subsequently designed models are also allowed to share the panel power management module, so that different models have better commonality.
