Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of illustrating the present disclosure and should not be construed as limiting the same.

A display panel assembly 100 according to an embodiment of the present disclosure is described below with reference to fig. 1-2. The display panel assembly 100 may be applied to an electronic device such as a cellular phone. In the following description of the present application, the display panel assembly 100 is described as an example of a mobile phone. Of course, those skilled in the art will appreciate that the display panel assembly 100 may also be applied to other types of electronic devices, such as tablet computers and the like.

As shown in fig. 1 and 2, a display panel assembly 100 according to an embodiment of the first aspect of the present disclosure includes a display panel 1 and a backlight source.

The display panel 1 includes a display portion. For example, in the example of fig. 1, the display panel 1 is substantially rectangular, and the entire surface of the display panel 1 is a display portion, in this case, the mobile phone is a full-screen mobile phone. Of course, the present disclosure is not limited thereto, and in other examples of the present disclosure, the display panel 1 may further include a non-display portion, for example, the non-display portion may be disposed around the display portion. Here, the "display portion" is a region used for display when the display panel 1 is used, and the "non-display portion" is a region not used for display by the display panel 1.

At least one through hole 11 is formed on the display part. The through hole 11 may penetrate the display panel 1 in a thickness direction of the display panel 1, and the through hole 11 is disposed on the display portion of the display panel 1.

One through hole 11 is shown in fig. 1 for illustrative purposes, but it is obvious to those skilled in the art after reading the following technical solutions that the solution can be applied to two or more through holes 11, which also falls within the protection scope of the present disclosure.

Corresponding parts can be installed at the through holes 11. For example, when the through holes 11 include a camera through hole, a camera may be installed at the through hole 11, and further, when the display panel assembly 100 is applied to a mobile phone such as a dual-camera mobile phone, there are two through holes 11, and one camera is installed in each through hole 11. Alternatively, the camera may be a 3D camera or the like. When the through hole 11 includes a handset through hole, a handset may be mounted at the through hole 11. It is understood that the number of the through holes 11 and the components mounted at the through holes 11 can be specifically set according to actual requirements to better meet the actual application.

The backlight Light source includes a plurality of LED (Light Emitting Diode) backlights, the plurality of LED backlights 2 are uniformly distributed right behind the display unit, and the plurality of LED backlights 2 are hidden from the through holes 11. For example, in the example of fig. 1, a plurality of LED backlights 2 are each located within the outer peripheral outline of the display portion of the display panel 1 in the thickness direction of the display panel 1. When the plurality of LED backlights 2 are turned on, the display portion of the display panel 1 located directly in front thereof may be directly turned on. Moreover, the plurality of LED backlights 2 are uniformly arranged right behind the display part, so that the brightness of the display part of the whole display panel 1 is uniform, and the problem that the brightness of the backlight source installed on the side surface of the screen is dark and non-uniform near the opening when the LCD panel is opened is solved. In the description of the present disclosure, "a plurality" means two or more.

According to the display panel assembly 100 of the embodiment of the first aspect of the present disclosure, by uniformly distributing the plurality of LED backlights 2 directly behind the display portion, the brightness of the display portion of the entire display panel 1 can be well made uniform.

According to some embodiments of the present disclosure, the maximum width of each LED backlight 2 in its cross-section is w, where w satisfies: w is more than or equal to 0.01mm and less than or equal to 1 mm. Therefore, if the maximum width w of each LED backlight 2 on the cross section thereof is less than 0.01mm, although the backlight can be controlled better, the display is more uniform, but since the size of the LED backlight 2 is smaller, the manufacturing difficulty is increased, and the cost is increased; if the maximum width w of each LED backlight 2 in its cross section is larger than 1mm, although the number of LED backlights 2 is relatively small, which saves cost, the luminance of the display portion may not be uniform enough. That is, the maximum width w is set to satisfy 0.01mm w 1mm, so that the manufacturing difficulty of the LED backlight 2 can be reduced and the cost can be reduced while the brightness display is ensured to be uniform.

It will be appreciated that the number of LED backlights 2 may be specifically set according to actual needs, for example, up to ten thousand. The greater the number of LED backlights 2, the better the backlight control, and the more uniform the display.

Optionally, a plurality of LED backlights 2 are arranged in an array. For example, in the example of fig. 1, a plurality of LED backlights 2 are arranged in a plurality of rows and columns.

According to a further embodiment of the present disclosure, a light guide plate is disposed between two adjacent LED backlights 2. Thus, the brightness of the display portion can be improved by providing the light guide plate. Of course, according to other embodiments of the present disclosure, there may be no light guide plate between two adjacent LED backlights 2.

Furthermore, a reflecting plate is arranged behind the backlight source. Thus, the brightness of the display portion can be further improved by providing the reflector. Of course, the present disclosure is not limited thereto, and the rear of the backlight source may not be provided with the reflection plate.

The memory can be used for storing software programs and modules, and the processor executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory. The memory can mainly comprise a program storage area and a data storage area, wherein the program storage area can store an operating system, application programs (such as a sound playing function and an image playing function) required by at least one function and the like; the storage data area may store data (e.g., audio data, a phonebook, etc.) created according to the use of the cellular phone, etc. Further, the memory may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit may be used to receive input numeric or character information and generate key signals related to user settings and function control of the cellular phone. Specifically, the input unit may include a touch panel and other input devices. The touch panel, also called a touch screen, may collect touch operations of a user (for example, operations of the user on or near the touch panel using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor, and can receive and execute commands sent by the processor. In addition, the touch panel may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit may include other input devices in addition to the touch panel.
