Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

The embodiment of the present disclosure provides a display module, a structure of which is schematically shown in fig. 2, including:

a backlight source, a back plate 105, a middle frame 103, a front frame 104 and a display panel 101; wherein the content of the first and second substances,

the backlight comprises a diffuser plate 109, and a plurality of minileds 111 are arranged in the expansion space between the diffuser plate 109 and the supporting surface of the middle frame 103.

The display module assembly of the embodiment of the disclosure is an improvement of the existing display module assembly, and the basic structure of the display module assembly is the same as that of the existing display module assembly, namely, the front frame wraps the display panel and the middle frame, the middle frame is embedded with the back plate, and the backlight source is arranged among the middle frame, the display panel and the back plate.

The backlight source further comprises an optical film material 102, a light bar substrate 106, a reflecting sheet 107 and a plurality of LEDs 108; the optical film material is arranged above the diffusion plate, the light bar substrate is arranged on the back plate, the reflector plate is arranged on the light bar substrate, and the LEDs are distributed on the reflector plate.

Because the minileds are located below the diffuser plate, in order to avoid the diffuser plate from crushing the minileds, the backlight source of the embodiment of the disclosure further includes diffuser plate supporting pillars 110 and/or diffuser plate supporting retaining walls 110, which are connected to the diffuser plate and the supporting surface of the middle frame, so as to support the diffuser plate and protect the minileds. A schematic structure of a display module with diffuser plate supporting pillars and/or diffuser plate supporting retaining walls can be shown in fig. 3.

To ensure that the light emitted by the MiniLED is not blocked, the diffuser plate support posts are preferably transparent. When specifically setting up, the diffuser plate support column can be a plurality of to guarantee better support nature. In order to support the diffuser plate with minimal interference to the minileds, the diffuser plate support posts are all disposed outside all the minileds.

For the arrangement of minileds, the minileds may be arranged on the supporting surface of the middle frame in a row, of course, may also be arranged on the supporting surface of the middle frame in a multiple row, and may be specifically arranged according to actual requirements, for example, may also be arranged in a predetermined pattern, and is not limited herein.

In general, MiniLED may be configured as white MiniLED to reduce the production cost of the display module, but if the problem of yellowing of the peripheral image of the display module is to be further solved, MiniLED needs to be configured as blue MiniLED, which can solve the problem of yellowing of the peripheral image of the display module although the cost is increased, and the display effect is better.

The embodiment of the present disclosure further provides an electronic device, which includes the display module in the above embodiment, and the specific structure of the display module refers to the above embodiment, which is not described herein again.

The embodiment of the disclosure optimizes the image quality of the backlight image improving module, so that the peripheral brightness of the module is more uniform, thereby improving the display effect; the blue MiniLED is added at the periphery of the backlight source to improve the image quality at the periphery of the direct type module, so that the problem of yellowing of a display picture of the module is solved, and the problem of relatively serious display is solved at the minimum cost.
