Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
A kind of mobile terminal that the utility model preferred embodiment provides, this mobile terminal has two-sided display screen.This mobile terminal can be the terminal device with display screen such as surface computer, mobile phone, PAD.As shown in Figure 1, two-sided display screen comprises two buffer layer 1a, 1b, two-layer low-temperature polycrystalline silicon layer 2a, 2b, two-layer packaged glass layer 3a, 3b and two-layer polaroid 4a, 4b.
Two buffer layer 1a, 1b are connected.Two-layer low-temperature polycrystalline silicon layer 2a, 2b are separately positioned on the relative both sides of cushion.Cushion 1a is connected with low-temperature polycrystalline silicon layer 2a, and cushion 1b is connected with two low-temperature polycrystalline silicon layer 2b.
Two-layer packaged glass layer 3a, 3b are connected to low-temperature polycrystalline silicon layer 2a, 2b described in two, and namely packaged glass layer 3a is connected with low-temperature polycrystalline silicon layer 2a, and packaged glass layer 3b is connected with low-temperature polycrystalline silicon layer 2b; And described packaged glass layer 3a is arranged at the relative surface away from described cushion 1a on described low-temperature polycrystalline silicon layer 2a, packaged glass layer 3b is arranged at the relative surface away from described cushion 1b on described low-temperature polycrystalline silicon layer 2b.At least touch control component is embedded with in one deck in two-layer described packaged glass layer 3a, 3b.
Described polaroid 4a, 4b are two-layer, are connected to packaged glass layer 3a, 3b described in two.That is, polaroid 4a is connected to packaged glass layer 3a, and described polaroid 4a is arranged at the relative surface away from described low-temperature polycrystalline silicon layer 2a on packaged glass layer 3a; Polaroid 4b is connected to packaged glass layer 3b, and described polaroid 4b is arranged at the relative surface away from described low-temperature polycrystalline silicon layer 2b on packaged glass layer 3b.
Utilize cushion 1a, 1b by two-layer low-temperature polycrystalline silicon layer 2a, 2b isolation, two-layer buffering between low-temperature polycrystalline silicon layer 2a, 2b can be realized, avoid two-layerly directly contacting between low-temperature polycrystalline silicon layer 2a, 2b.Low-temperature polycrystalline silicon layer 2a, 2b are LTPS (LowTemperaturePoly-silicon), and it can realize autoluminescence, thus does not need backlight, to reduce the thickness of two-sided display screen.Utilize two-layer low-temperature polycrystalline silicon layer 2a, 2b, two-layer packaged glass layer 3a, 3b, two-layer polaroid 4a, 4b can form two display modules, thus realize double-sided display.
At least touch control component is embedded with in one deck in two-layer described packaged glass layer 3a, 3b.Touch control component can be embedded in packaged glass layer 3a, 3b by oncell or incell technology, by touch control component being embedded in packaged glass layer 3a, 3b, two parts are integrated, the thickness of two-sided display screen can be made to reduce obviously, be conducive to mobile terminal device and do thin doing gently.
Wherein be embedded with touch control component in one deck packaged glass layer, one side touch-control can be realized, as embedded touch control assembly equal in two-layer packaged glass layer, then can realize two-sided touch-control.In the present embodiment, only embedded touch control assembly in one deck packaged glass layer 3a.Certainly, in other embodiments, in order to realize two-sided touch-control, then in two-layer described packaged glass layer 3a, 3b, all touch control component can be embedded with.
As preferably, cushion 1a, 1b are buffering foam, so that processing preparation, reduce costs.Certainly cushion 1a, 1b also can adopt EVA or other buffering materials in other embodiments.In the present embodiment, described cushion 1a, 1b is two-layer, cushion 1a described in adjacent one successively, low-temperature polycrystalline silicon layer 2a described in one, described in one, polaroid 4a described in packaged glass layer 3a and is connected to form holistic display module, cushion 1b described in adjacent one successively, low-temperature polycrystalline silicon layer 2b described in one, described in one, polaroid 4b described in packaged glass layer 3b and is connected to form holistic display module, two display modules can be formed, in processing preparation process, first can process and prepare two display modules, again by the cushion 1a of two display modules, 1b is connected can form two-sided display screen, be beneficial to processing preparation.As preferably, two-layer described bonding between cushion 1a, 1b, so that the connection between two cushion 1a, 1b.Herein, in other embodiments, cushion may also be only one deck, utilizes one deck cushion two-layer low-temperature polycrystalline silicon layer 2a, 2b to be connected.
In the present embodiment, the thickness of described cushion is 0.16mm, and the thickness of described low-temperature polycrystalline silicon layer is 0.211mm, and the thickness of described packaged glass layer is 0.205mm, and the thickness of described polaroid is 0.163mm.The thickness of whole two-sided display screen is (0.163mm+0.205mm+0.211mm+0.16mm) × 2=1.478mm, and its thickness hinge structure can reduce greatly, is beneficial to mobile terminal and does thin doing gently.
Further, two-sided display screen also comprises can cover plate (not shown), and described cover plate is bonded on described polaroid 4a by gum.Protection can be formed to polaroid 4a by cover plate, increase the service life.Described cover plate be positioned at be embedded with touch control component described packaged glass layer 3a away from the side of described cushion 1a.Owing to being embedded with the polaroid 4a side of the packaged glass layer 3a of touch control component for user's touch-control, its wearing and tearing are comparatively large, utilize cover plate effectively to protect this polaroid 4a, effectively extend the serviceable life of two-sided display screen.If two-sided display screen is two-sided touch-control, then cover plate can be two, is bonded on two polaroids 4a, 4b respectively by gum.
As preferably, described gum is OCA optical cement or OCR optical cement, to improve transmittance, improves two-sided display screen.
After the two-sided display screen of the present embodiment increases cover plate and gum, the thickness of cover plate is 0.55mm, the thickness of gum is 0.15mm, the thickness of whole display screen is then 1.478mm+0.55mm+0.15mm=2.178mm, double-side liquid crystal display screen thickness in hinge structure reduces 3.125mm-2.178mm=0.947mm, thickness reduces obviously, and what be conducive to mobile terminal does thin doing gently.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
