Problems solved by technology

However, since there are heat sources such as light sources inside the display device, the ambient temperature often rises during use, thus causing the chip element to expand when exposed to heat.
When the sheet element expands, it will be pushed by the counter force of the solid positioning block due to the compression of the solid positioning block, and then bend or arch, causing problems in image display or optical taste

Embodiment Construction

[0042] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” or “connected to” another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present.

[0043] Additionally, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element as shown in the figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of t...

Abstract

The invention provides a block, a backlight module using the same and display equipment. The block contains an outer bag and phase change material. The outer bag surrounds the block so that an accommodation cavity is formed in the interior. However, the phase change material is accommodated into the accommodation cavity. At least a part of the outer bag is made of elastic material while the melting point of the phase change material is lower than that of the elastic material. The backlight module contains an optical diaphragm, a frame body and the above block. The frame body at least partiallysurrounds the side edge of the optical diaphragm while the block is arranged between the optical diaphragm and the frame body. The display equipment comprises a display panel, the frame body and theabove block. The frame body has an accommodation area used for accommodating a display panel while the block is arranged between the display panel and the frame body.

Description

technical field [0001] The present invention relates to a display device and a backlight module; specifically, the present invention relates to a display device with a stopper and a backlight module. Background technique [0002] Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and so on. However, in order to improve the user's visual experience, the industry is still constantly improving the optical performance of the display device. [0003] As far as the traditional display device is concerned, the chip components such as the display panel or the light guide plate are usually supported by a plastic frame. In order to locate the relative positional relationship between the chip component and the plastic frame, a solid positioning block extended or formed by the plastic frame or the chip component is us...
