Patent Application
20240008169
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.
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.
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.
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 to
In an embodiment, the electronic device 10 is a notebook computer, or other electronic devices having a display panel, but the disclosure is not limited thereto.
Because the first type display panel 121 is a display panel 12 that requires power management provided by the panel power management module 20, in an embodiment, the first type display panel 121 is an organic light-emitting diode (OLED) panel. As shown in
In an embodiment, since the panel power management module 20 is an independent module and a non-fixed mobile device, the panel power management module is mounted at any vacant position in the electronic device 10. In an embodiment, the panel power management module 20 is mounted in a frame of the first type display panel 121.
Since the second type display panel 122 is a display panel 12 that does not require the panel power management module 20, in an embodiment, the second type display panel 122 is an in-plane-switching (IPS) liquid crystal panel. As shown in
In an embodiment, referring to
Furthermore, as shown in
Therefore, as shown in
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.
The embodiments described above are only used for explaining the technical ideas and characteristics of the disclosure to enable a person skilled in the art to understand and implement the content of the disclosure, and are not intended to limit the patent scope of the disclosure. That is, any equivalent change or modification made according to the spirit disclosed in the disclosure shall still fall within the patent scope of the disclosure.
