Embodiment
For making those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1:
The present embodiment provides a kind of display device, comprises display panel, described display panel preferably organic LED display panel.
The display device of the present embodiment also comprises carriage, and described carriage is positioned at least one edge part of described display panel, and as shown in Figure 3, Figure 4, carriage 2 is preferably positioned at four edge parts of described display panel 1.Visible, carriage clamps four edge parts of described display panel 1 to support fixing described display panel 1.
Be understandable that, the carriage 2 shown in Fig. 3, Fig. 4 can clamp four edge parts of display panel 1, now maximum to the support fixation of display panel 1, and described carriage 2 can play the effect of protection display panel 1 simultaneously.That is, the display device of the present embodiment can remove front frame and backboard, and support fixing described display panel only by carriage 2, simultaneously because the structure of carriage 2 is relatively simple, therefore manufacturing process simply, easily realizes, and need not assemble, make production time minimizing, cost reduction.
As shown in Figure 4, before carriage 2, the open region of (with the face of the display surface homonymy of display panel 1) is slightly larger than the viewing area (in figure, dashed region is the viewing area of display panel 1) of display panel 1, and be understood that, this design is convenient to display device and is shown.As shown in Figure 3, the open region at carriage 2 back side (with face relative above) can be less, this is because when carriage 2 clamps display panel 1, the back side (namely relative with display surface in display panel 1 face) of what the open region at carriage 2 back side was corresponding is display panel 1, the described back side is also not used in display, so the open region design at carriage 2 back side is smaller, carriage 2 will with the dorsal edge portion of display panel 1 outside can form a blocked area, described blocked area can be used for blocking some necessary parts, make some necessary parts of the display device of the present embodiment need not be directly outside exposed, also just ensure that outward appearance tidiness and the landscaping effect of described display device.It should be noted that, concrete size the present invention of the open region at carriage 2 back side does not limit, and specifically arranges according to specific needs.
Specifically, display device comprises printed circuit board (PCB), preferably, described printed circuit board (PCB) is positioned at outside the edge part at the back side of display panel 1, and be arranged in carriage 2 (being namely positioned at blocked area), and be connected with display panel 1 by covering brilliant film (COF, ChipOnFilm).
Wherein, cover brilliant film and refer to fexible film with chip, thus it both can make driving chip (DriverIC) be connected with printed circuit board (PCB), and driving chip can be made again to be connected with display panel 1; Owing to covering the shape needed for brilliant thin film, flexible one-tenth, therefore it arranges facility, and adaptability is good.
Further preferably, described printed circuit board (PCB) comprises power circuit, provides power supply and signal for giving described display panel 1.
It should be noted that, described carriage 2 is positioned at four edge parts of described display panel 1, in order to easy for installation, succinct, preferably, have at least in four limits of described carriage 2 while can insert and tear open, to guarantee that carriage 2 easier can clamp four edge parts of described display panel.
Need to further illustrate, the structure of described carriage 2 is not limited to above-mentioned situation, and as shown in Figure 5, carriage 2 is preferably positioned at three edge parts of display panel 1; As shown in Figure 6, carriage 2 is preferably positioned at an edge part of display panel 1.In fact, as long as carriage 2 is positioned at least one edge part of described display panel 1, and the edge part clamping described display panel 1 can realize the effect supporting fixing described display panel 1.Be understandable that; concrete which or which edge part that described carriage 2 is positioned at display panel 1 is all feasible; preferably; described carriage 2 and described printed circuit board (PCB) are positioned at the identical edge part of display panel 1, such being designed be beneficial to realize carriage 2 pairs of printed circuit board (PCB)s block protection.
As shown in Figure 7, Figure 8, be the display panel 1 of the display device of the present embodiment, preferably, outside its back side, be also provided with protective seam 3.This protective seam 3 can increase physical strength and the environmental reliability of display panel 1; why protective seam 3 is set; because when the opening at carriage 2 back side is larger; and display panel 1 is when being large size panel; if there is no protective seam 3; so the back side of display panel 1 has is direct exposed (part that carriage 2 can't stop) out greatly; the environmental reliability of the display panel 1 of this area is poor; and this problem can be solved by protective seam 3, improve physical strength and the environmental reliability of the entirety of display panel 1.
Preferably, the material of described protective seam 3 be in aluminium, copper, zinc paste, platinum any one.Such as; the material of described protective seam 3 can be aluminium or copper; why select aluminium or copper as the material of protective seam 3; because aluminium or copper are except increasing except physical strength; its heat conductivility is good, the heat produced effectively can be spread out by described protective seam 3, be understandable that in display device use procedure; protective seam 3 directly contacts with air, and the quality of its heat conductivility directly affects the integral heat sink effect of display device.Certainly, the price of aluminium or copper is lower, also can reduce the production cost of display device.
In addition; the material of described protective seam 3 can also be metal oxide; such as zinc paste etc.; this be consider zinc paste there is good anti-oxidation, anticorrosion ability because protective seam 3 some be exposed aerial, comprise oxygen and steam in air; when the material of protective seam 3 is zinc paste; it effectively can avoid the harmful effect that in air, oxygen shines with steam etc., thus ensureing the physical strength of display panel simultaneously, also improves environmental reliability.
Certainly; protective seam 3 can also be organic protection layer; such as PET(polyethylene terephthalate) etc. insulation anti-scratch material layers; the protective seam 3 of these materials also can provide good physical strength and environmental reliability; the material of concrete protective seam 3 can carry out difference selection according to specific needs, and the present invention does not limit.
Preferably, described protective seam 3 is formed by attaching method or evaporation coating method.
Concrete attaching method and evaporation coating method are prior art; the present invention is not specifically limited; it should be noted that; as as described in Fig. 7, Fig. 8; described protective seam 3 is the back side being positioned at described display panel 1, and that is protective seam 3 is not used in display, therefore can form various pattern at protective seam 3 outside surface according to specific needs and carry out outward appearance and beautify; namely realized the personalized design of this display device by protective seam 3, make it have unique outward appearance.
Certainly, other conventional structures can also be comprised in the display device of the present embodiment, as power supply unit, display driver unit etc.
Be understandable that, the illustrative embodiments that above embodiment is only used to principle of the present invention is described and adopts, but the present invention is not limited thereto.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement are also considered as protection scope of the present invention.
