本申请涉及显示技术领域，尤其涉及一种背光模组、显示模组、屏下光学指纹***及电子装置。This application relates to the field of display technology, in particular to a backlight module, a display module, an under-screen optical fingerprint system and an electronic device.

背景技术Background technique

液晶显示器(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，被广泛的应用于电视、电脑、手机等电子产品中。LCD显示器是一种被动发光显示器，其显示屏本身并不能发光，而是由显示屏背后的背光模组照亮的，其显示面板通常由液晶面板和背光模组相平行设置并通过黑胶紧贴形成，其中，背光模组包括光源和与光源相连的导光模组，且光源和导光模组的高度相同，使背光模组整体为一个高度的平面，光源的光线经过导光模组的处理后发射出来，均匀的照射在液晶显示面板上，从而使显示面板显示图案。随着显示技术的发展，如指纹识别等附加功能逐渐被广泛使用在显示设备中，具有指纹识别等功能的显示面板也受到了广泛的研究。Liquid crystal display (LCD) has many advantages such as thin body, power saving, and no radiation, and is widely used in electronic products such as TVs, computers, and mobile phones. The LCD display is a passive light-emitting display. The display itself does not emit light, but is illuminated by the backlight module behind the display. The display panel is usually arranged in parallel with the liquid crystal panel and the backlight module and tightly secured by black glue. The backlight module includes a light source and a light guide module connected to the light source, and the height of the light source and the light guide module are the same, so that the backlight module is a high plane, and the light from the light source passes through the light guide module After processing, it is emitted and irradiated uniformly on the liquid crystal display panel, so that the display panel displays patterns. With the development of display technology, additional functions such as fingerprint recognition have gradually been widely used in display devices, and display panels with functions such as fingerprint recognition have also been extensively studied.

目前，现有的光学指纹显示模组，如图1所示，包括指纹模组、液晶面板和背光模组，其中，液晶面板位于背光模组上方，且液晶面板和背光模组均为平面，由于背光模组无法穿透光线，为满足指纹模组的识别性能，需将指纹模组设置在液晶面板的一端与背光模组的一端之间，液晶面板的另一端和背光模组的另一端通过黑胶粘接，形成LCD光学指纹识别显示模组。At present, the existing optical fingerprint display module, as shown in Figure 1, includes a fingerprint module, a liquid crystal panel, and a backlight module. The liquid crystal panel is located above the backlight module, and the liquid crystal panel and the backlight module are both flat. Since the backlight module cannot penetrate light, in order to meet the recognition performance of the fingerprint module, the fingerprint module needs to be placed between one end of the LCD panel and one end of the backlight module, the other end of the LCD panel and the other end of the backlight module Through the black glue bonding, the LCD optical fingerprint recognition display module is formed.

然而，在现有的显示模组中，增设的功能模组会使液晶面板和背光模组之间形成间距较大的间隙，而且形成的间隙间距并不一致，导致背光模组和液晶面板之间不能紧贴，使显示模组的显示亮度不均匀，影响显示效果。However, in the existing display modules, the additional functional modules will cause a gap between the liquid crystal panel and the backlight module to be larger, and the gaps formed are not uniform, resulting in a gap between the backlight module and the liquid crystal panel. It cannot be close to each other to make the display brightness of the display module uneven and affect the display effect.

实施例一Example one

图3是本发明实施例一提供的一种背光模组的结构示意图。3 is a schematic structural diagram of a backlight module provided by Embodiment 1 of the present invention.

本发明的第一方面提供一种背光模组10，用于与液晶面板20贴合形成显示模组，背光模组10位于显示模组的背后且可提供光源，其功能是供应充足的亮度与分布均匀的光源，以使显示模组能够正常的显示影像。The first aspect of the present invention provides a backlight module 10 for bonding with a liquid crystal panel 20 to form a display module. The backlight module 10 is located behind the display module and can provide a light source. Its function is to supply sufficient brightness and Evenly distributed light sources, so that the display module can display images normally.

现有的显示模组通常由背光模组10和液晶面板20贴合形成，如图2所示，背光模组10包括光源板13和导光模组14，液晶面板20可分为显示区域22和非显示区域21，其中显示区域22用于图案的显示，液晶面板20上还覆盖玻璃盖板50。背光模组10和液晶面板20均为水平的平面，背光模组10和液晶面板20平行设置，并通过两端的黑胶40紧贴形成显示模组，背光模组10与液晶面板20之间等间距设置，这样从背光模组10出来的光线能够均匀的照射在液晶面板20上，保证了液晶面板显示区域22亮度的均匀性，提高了显示的效果。在现有的显示模组中增加一些功能性模组时，如背景技术中所述，增设的功能模组30位于液晶面板20的一端与背光模组10的一端之间，液晶面板20的另一端与背光模组10的另一端通过黑胶40粘接，这样就使液晶面板20和背光模组10之间形成较大的间隙，且两者之间形成的间隙间距并不一致，使显示模组的显示亮度不均匀，降低了显示效果。The existing display module is usually formed by bonding a backlight module 10 and a liquid crystal panel 20. As shown in FIG. 2, the backlight module 10 includes a light source plate 13 and a light guide module 14. The liquid crystal panel 20 can be divided into a display area 22. And the non-display area 21, where the display area 22 is used for pattern display, and the liquid crystal panel 20 is also covered with a glass cover 50. The backlight module 10 and the liquid crystal panel 20 are both horizontal planes, the backlight module 10 and the liquid crystal panel 20 are arranged in parallel, and the black glue 40 at both ends is closely attached to form a display module, between the backlight module 10 and the liquid crystal panel 20, etc. The spacing is set so that the light from the backlight module 10 can be uniformly irradiated on the liquid crystal panel 20, which ensures the uniformity of the brightness of the display area 22 of the liquid crystal panel, and improves the display effect. When adding some functional modules to the existing display module, as described in the background art, the added functional module 30 is located between one end of the liquid crystal panel 20 and one end of the backlight module 10, and the other of the liquid crystal panel 20 One end and the other end of the backlight module 10 are bonded by black glue 40, so that a larger gap is formed between the liquid crystal panel 20 and the backlight module 10, and the gap distance between the two is not consistent, so that the display module The display brightness of the group is uneven, which reduces the display effect.

基于上述原因，本发明实施例提供一种背光模组10，用于与液晶面板贴合形成显示模组，如图3所示，该背光模组10包括与液晶面板非显示区域相对的第一平面11，以及与液晶面板显示区域相对的第二平面12，其中，平面是指与水平方向平行的平面，即第一平面11和第二平面12为两个相互平行的水平平面。背光模组10包括有第一平面11和第二平面12，需要说明的是，第一平面11的一端和第二平面12一端相连接以保证背光模组10的性能，其中，在将背光模组10和液晶面板贴合形成显示模组时，背光模组10的第一平面11与液晶面板的非显示区域相对设置，背光模组10的第二平面12与液晶面板的显示区域相对设置。Based on the above reasons, an embodiment of the present invention provides a backlight module 10 for bonding with a liquid crystal panel to form a display module. As shown in FIG. 3, the backlight module 10 includes a first backlight module opposite to the non-display area of the liquid crystal panel. The plane 11 and the second plane 12 opposite to the display area of the liquid crystal panel, wherein the plane refers to a plane parallel to the horizontal direction, that is, the first plane 11 and the second plane 12 are two horizontal planes parallel to each other. The backlight module 10 includes a first plane 11 and a second plane 12. It should be noted that one end of the first plane 11 and one end of the second plane 12 are connected to ensure the performance of the backlight module 10. When the group 10 and the liquid crystal panel are bonded to form a display module, the first plane 11 of the backlight module 10 is arranged opposite to the non-display area of the liquid crystal panel, and the second plane 12 of the backlight module 10 is arranged opposite to the display area of the liquid crystal panel.

为在设置功能模组后仍能保证显示亮度的均匀性，在本实施例中，如图3所示，第一平面11在竖直方向上低于第二平面12，使背光模组10在第一平面11处形成用于容纳功能模组的容纳空间16，其中，竖直方向是指垂直于水平的方向，即背光模组10的第一平面11和第二平面12为竖直方向上高度不同的两个平面，且第一平面11的竖直高度较低，这样就在背光模组10的第一平面11处留出了容纳空间16，功能模组就能够设置在该容纳空间16内，在与液晶面板贴合时，第一平面11与非显示区域相对，第二平面12与显示区域相对，功能模组就可以设置于背光模组10的第一平面11处的容纳空间16内，而第一平面11和第二平面12为高度不同的两个平面，这样就使第二平面12和液晶面板显示区域朝向第二平面12的一面能够等间距的设置，从而使背光模组10的光线可均匀的照射到液晶面板的显示区域上，从而保证了显示亮度的均匀性，提高了显示效果。In order to ensure the uniformity of the display brightness after the function modules are installed, in this embodiment, as shown in FIG. 3, the first plane 11 is lower than the second plane 12 in the vertical direction, so that the backlight module 10 is An accommodating space 16 for accommodating functional modules is formed at the first plane 11, where the vertical direction refers to a direction perpendicular to the horizontal, that is, the first plane 11 and the second plane 12 of the backlight module 10 are in the vertical direction. Two planes with different heights, and the vertical height of the first plane 11 is relatively low, so that an accommodating space 16 is left at the first plane 11 of the backlight module 10, and the functional module can be arranged in the accommodating space 16 Inside, when attaching to the liquid crystal panel, the first plane 11 is opposite to the non-display area, and the second plane 12 is opposite to the display area. The functional module can be arranged in the accommodation space 16 of the first plane 11 of the backlight module 10 The first plane 11 and the second plane 12 are two planes with different heights, so that the second plane 12 and the liquid crystal panel display area facing the second plane 12 can be arranged at equal intervals, so that the backlight module The light of 10 can be evenly irradiated on the display area of the liquid crystal panel, thereby ensuring the uniformity of the display brightness and improving the display effect.

在本实施例中，第一平面11在竖直方向上低于第二平面12的具体数值可根据实际需求中设置的功能模组的厚度进行选择设置，需要说明的是，由于在与液晶面板贴合时，通过黑胶将第二平面12的一端与液晶面板显示区域的一端粘接，使显示区域朝向第二平面12的一面与第二平面12之间具有等距的间距，则第一平面11在竖直方向上低于第二平面12的具体数值可通过使用功能模组的厚度减去显示区域朝向第二平面12的一面与第二平面12之间的间距数值来获得。具体的，如功能模组30的厚度为1mm，而将该背光模组10与液晶面板贴合后，显示区域朝向第二平面12的一面与第二平面12之间具有0.5mm的间距，则第一平面11可在竖直方向上低于第二平面12的高度值为0.5mm。In this embodiment, the specific value of the first plane 11 in the vertical direction that is lower than the second plane 12 can be selected and set according to the thickness of the functional module set in actual needs. It should be noted that the When bonding, one end of the second plane 12 is bonded to one end of the display area of the liquid crystal panel through black glue, so that the side of the display area facing the second plane 12 and the second plane 12 are equidistant, then the first The specific value of the plane 11 lower than the second plane 12 in the vertical direction can be obtained by using the thickness of the functional module minus the value of the distance between the side of the display area facing the second plane 12 and the second plane 12. Specifically, if the thickness of the functional module 30 is 1 mm, and after the backlight module 10 is bonded to the liquid crystal panel, there is a 0.5 mm gap between the side of the display area facing the second plane 12 and the second plane 12, then The first plane 11 may have a height value of 0.5 mm lower than the second plane 12 in the vertical direction.

进一步的，在本实施例中，背光模组10包括导光模组14和光源板13，导光模组14位于第二平面12对应的区域内，光源板13位于第一平面11对应的区域内，如图3所示，导光模组14的一端和光源板13的一端相连，光源板13为背光模组10提供光源，光源板13发出的光经过导光模组14处理后发射出来。导光模组14位于第二平面12对应的区域内，光源板13位于第一平面11对应的区域内，可以通过使光源板13设置的竖直高度小于导光模组14设置的竖直高度，即将光源板13的设置位置下沉，也就能够使第一平面11在竖直方向上低于第二平面12，以使背光模组10在光源板13对应的位置处留出容纳空间16来设置功能模组。Further, in this embodiment, the backlight module 10 includes a light guide module 14 and a light source plate 13. The light guide module 14 is located in an area corresponding to the second plane 12, and the light source plate 13 is located in an area corresponding to the first plane 11. Inside, as shown in FIG. 3, one end of the light guide module 14 is connected to one end of the light source board 13.

The light guide module 14 is located in the area corresponding to the second plane 12, and the light source plate 13 is located in the area corresponding to the first plane 11. The vertical height of the light source plate 13 can be made smaller than the vertical height of the light guide module 14. That is, the setting position of the light source board 13 is lowered, so that the first plane 11 is lower than the second plane 12 in the vertical direction, so that the backlight module 10 leaves an accommodation space 16 at the position corresponding to the light source board 13 To set up the function module.
