For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in instructions of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Please refer to Fig. 1, the display module that the utility model one embodiment provides comprises framework 10 and main circuit board 20.Described framework 10 is for carrying other elements of main circuit board 20 and display module, such as display panel, various optical sheet (diffusion sheet, reflector plate, light guide plate etc.), display panel and these optical sheets do not relate to improvement of the present utility model, so there is no illustrate in the drawings.Shown in Fig. 1 is only the displaying of the relative position relation of framework 10 and main circuit board 20, is not that the concrete structure after this display module finished product is shown.
Simultaneously with reference to figure 2, framework 10 is in framework shape, and have four sides (three sides 11,12,13 are only shown in Fig. 2) that head and the tail connect, four sides are enclosed to form an opening 101, and this opening 101 is corresponding with the viewing area of display panel.
Framework 10 is provided with light trough 110, the light source of light trough 110 on accommodating backlight, and this is hereinafter by further specified.Particularly, light trough 110 is arranged on a side 11 of framework 10.Light trough 110 can be positioned at the inside edge place of side 11, and can be communicated with opening 101, and in such cases, light trough 110 is actually the breach being opened in side 11 inside edge.Light trough 110 also can between the inside edge of side 11 and outer edge, and in such cases, light trough 110 is the through hole offered on side 11.
In the present embodiment, framework 10 is rectangular, and side 11 is minor face, and side 12,13 is long limit, and this display module can be applicable in the electronic installation such as mobile phone or panel computer.Be appreciated that framework 10 can be other shapes, with the mating shapes of the electronic installation with application.
Simultaneously with reference to figure 3, main circuit board 20 comprises body region 21, and the first interface district 201 be all connected with body region 21 and the second interface area 202.This main circuit board 20 is for being electrically connected with the display panel of display module.Particularly, first, second interface area 201,202 described is respectively used to be electrically connected with the power supply and display panel that show module.
