1) Check if the screen responds to any touch at all. If it does work but you get “ghost touch”, problem is likely going to be fixed without replacing the screen. Usually one of the connectors are dirty or not plugged in correctly. Easier fix is to open the iphone, lift the screen from the rest of the case/motherboard and unplug the lcd and other connectors that run from the screen to the board. You could use 99% alcohol and a tooth brush. Scrub the connectors gently and wait a few seconds for the alcohol to evaporate before plugging the connectors in. Usually this will fix the trouble and you will have a perfectly working phone without replacing any parts. IMPORTANT: Do not use 50% or 75% alcohol or acetone. Low grade alcohol is 50% water (and we know what water does to the phones)and the acetone can short out the motherboard or melt the certain parts that are important.

The iphone uses BGA type of chips for all of their phones. These are “ball grid array” chips and they have these tiny little ball of solder that connect to the board. Some may have 10 and some chips have 50-60 or more of them. You can not see them like you would on a SM chip(surface mount). While you are using the phone they have electricity running through them . This makes them heat up and cool down constantly. Problem that occurs is called “Cold solder”. Over the time because of it heating and cooling the solder become brittle and it cracks. Once it cracks it will start to cause problems. This is why sometimes if you press the phone in certain spot it actually starts to work. Well, you are forcing the chip to connect to the board by pressing it in, but once you let go it stops. This sometimes can be fixed by reheating the chip, or to use technical term, “re-flowing”. sometimes it needs so little that the heat may just connect the broken link and it will be fine. Temperature you use to reheat it very important. If you take it to the shop and you see them using one of those industrial heat guns used to strip the paint from home depot, you will probably need a new phone. Temperature is important, but the force of the air flow just as important.

I know most people wont read this whole thing, but there is some useful information I wrote here and everything I wrote applies to almost any phone on market today. All of the phones are basically the same. They all have the same parts, only difference if what those parts are going to look like and their location o the phone, but they all need to have the CPU’s, memory chips, power management chips, lcd or touch controller chips and so on.

A polarizer removing device according to the present invention includes a fixing member fixing a liquid crystal display including a panel and a polarizer attached to the panel, a separator which separates an edge of a polarizer from the panel by inserting itself between the polarizer and the panel, a first moving member transferring the separator, a clamping member clamping the edge of the polarizer separated from the panel, and a second moving member moving the clamping member to separate the polarizer from the panel.

The clamping member has a fixing member coupled to the separator, a moving member installed to the fixing member with a gap, and a clamping cylinder coupled to the moving member to move toward or away from the fixing member.

A device for removing a polarizer of the present invention removes the polarizer from the panel. When the liquid crystal display is fixed by adsorption plate of vacuum adsorber of holder, a sharp edge of the separator is located in the edge part of the liquid crystal display. The separator gets inserted between the polarizer and the panel to separate the corner of the polarizer from the panel. When the clamping member clamps the edge of the polarizer separated from the panel, the second moving member moves the clamping member.

As shown in FIGS. 1-4, a polarizer remover of a liquid crystal display according to the present invention includes a fixing member fixing a liquid crystal display 2, a separator 20 which separates an edge of a polarizer 6 from the panel 4 by inserting itself between the polarizer 6 and panel 4, a first moving member transferring the separator 20, a clamping member clamping the edge of the polarizer 6 separated from the panel 4, and a second moving member moving the member to separate the polarizer 6 from the panel 4.

As shown in FIG. 3, the second moving member has a servomotor and a ball screw system. A ball screw shaft 34 is provided at the frame 8, and the servormotor 32 rotates the ball screw shaft 34. A ball nut 36 is coupled to the ball screw shaft 34 and moves according to the rotation of the ball screw shaft 34. A moving bracket 38 is provided at the ball nut 36.

The ball screw shaft 34 makes an angle with the liquid crystal display 2 such that the clamping member clamping the polarizer separated from the panel moves away from the working plate 10.

As shown in FIG. 2, the second moving member further includes at least one guide bar 35 and a connecting member 37. The guide bar 35 is parallel to and separated from the ball screw shaft 34. The connecting member 37 is movably coupled to the guide bar 35 and moves together with the ball nut 36.

As shown in FIG. 3, the first moving member includes a separating cylinder 42, a guide rail 44 and a separating bracket 48. The separating cylinder 42 is provided at the moving bracket 38 of the second moving member. The guide rail 44 is installed at the moving bracket 38 parallel to the working plate. The separating bracket 48 is movably installed along the guide rail 44 and coupled to a piston rod 43 of the separating cylinder 42.

As shown in FIG. 3, the clamping member includes a fixing member 54, a clamping bracket 58, a clamping cylinder 52 and a moving member 56. The fixing member 54 is installed at the separating bracket 48, and the separator 20 is provided at one end of the fixing member 54. The clamping bracket 58 is installed separated from the fixing member 54. The clamping cylinder 52 is installed at the clamping brackets 58. The moving member 56 is installed on the piston rod 53 of the clamping cylinder 52 and moves toward or away from the fixing member 54.

At an end portion of clamping bracket 58 corresponding to an end of separating member 20, a sensor 60 for detecting an edge of the polarizer is located.

For example, when the separator 20 separates the polarizer 6 of the panel 4, the separator 20 remains fixed by a torsion spring (not shown). When the second moving member moves the fixing member 54, the separator 20 rotates about the rotating pin 28 by the moving force of the second moving member. This overcomes elasticity force of torsion spring. So the sharp edge of the separator 20 is prevented from damaging the porarizer 6 (shown FIG. 9).

As shown in FIG. 1, the polarizer remover comprises a pushing member. The pushing member operates in response to the operation of the second moving member and push the liquid crystal display 2 to protect deformation of panel 4 while the polarizer 6 is separated from the panel 4.

When a polarizer of a liquid crystal display turns out to be wrong due to impurities accidentally involved between a panel and the polarizer, misattachment of the polarizer, or damages on the polarizer, as shown in FIG. 5, the liquid crystal display is loaded on the adsorb plate 12 by using a transferring system (not shown). At this time, the liquid crystal display 2 is located on the adsorbing plate 12 such that the polarizer 6 is projected over the fixing jig 16, and an edge of the polarizer 6 closely contact the fixing jig 16. The liquid crystal display 2 is adsorbed on the adsorbing plate 12 by the vacuum adsorber, and the servomotor 32 of the second moving member begins to rotate by a control signal of the controller (not shown). The ball screw shaft 34 rotates according to the rotation of the servomotor 32, the separator 20 moves toward the liquid crystal display 2.

As shown in FIG. 6, the working plate 10 rotates along the corner of polarizer such that the corner rotates from the dot-dash line to the solid line. As shown in FIG. 7, the separating bracket 48 moves toward the polarizer 6 along the guide rail by the separating cylinder 42 of the first moving member in response to the signal from the controller.

Then, the fixing member 54 and the separator 20 move toward the polarizer 6 and the separator 20 is inserted between the polarizer and the panel 4 to separate the corner of the polarizer 6 from the panel 4. When the separated portion of the polarizer 6 is placed between the clamping surfaces 55 of the fixing member 54 and the moving member 56 and the size of the separated portion becomes proper, the clamping cylinder 52 of the clamping member operate in response to the control signal of controller to move the moving member 56 toward the fixing member until the separated portion of the polarizer is clamped between the clamping surfaces 55.

The servomotor 32 of the second moving member rotates in response to the control signal of the controller to move the moving bracket 38 via the ball nut 36 coupled to the ball screw shaft 34. The moving direction of the moving bracket 38 is left in FIG. 8 such that the polarizer 6 is detached from the panel 4. Since the ball screw shaft 34 makes an angle with the working plate 10, the clamping surfaces 55 moves upward and left.

The pushing cylinder 72 operates according to the control signal from the controller when the second moving member operates, and the pushing roller 72 moves left to prevent the panel 4 from being damaged.

The polarizer 6 is completely detached from the panel the vacuum adsorber stops its operation, and the liquid crystal display 2 can be removed from the adsorb plate 12 to proceed to the next process.

Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.

The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.

Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.

Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.

Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.

One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.

Samsung has also been showing off its MicroLED display technology at recent trade shows, which uses self-emissive LED diodes to produce its pixels. However, in 2019 Samsung predicted that the technology was two or three years away from being viable for use in a consumer product.

A hallmark of Asian design for centuries, folding screens are simple, lightweight, and attractive. These room dividers hinge together three, four, or more panels that may be translucent (known as shojiin Japanese) or opaque (fusuma). A basic four-panel shoji screen can be had for about $100.

DIY a folding screen by stapling a favorite fabric onto panel frames. Tip:When attaching panels, mount hinges on alternating sides so the screen can fold up. (Check out this blogger’s supply listfor specifics.)

For instant space partitioning, call on a curtain. Suspend a rod from the ceiling and use rings or hooks to attach drapery panels. Think velvet for drama or go gauzy for a lighter look. Pull closed for privacy, open for spaciousness. Perfect for sectioning off a sleeping area in a studio apartment or mother-in-law suite.

If a curtain feels too flimsy, jump on the trendy barn door bandwagon, for under $200. Or build your own with guidance from This Old House’s Mark Powers.

For a simpler sliding door project, make a frame out of 2x2s, nail or glue on Masonite sheets, add wheels to the bottom and hinged loops to the top, then hang from plumbing pipe attached to the wall.

Often used in commercial or professional settings like meeting rooms, accordion doors suspend from an overhead track but eschew a floor track to avoid a tripping hazard. They’re typically manufactured from vinyl, laminates, wood, aluminum, or acrylic.

Some spaces—like a shared children’s bedroom or makeshift home office—will benefit from a partition with places to put things. These ideas fill the bill:

Any bookcase, set perpendicular to a wall instead of flush against it, becomes an instant room divider. Just be sure to secure it for safety: Attach metal L brackets to the top of the bookcase and a wall stud, then drive a few screws through the side of the unit into the same stud. For further insurance against tipping, anchor the bottom.

Go low with cubbies (a.k.a. cube storage) to delineate a border on the floor while maintaining open space above. This eight-cube organizer got raves from a reviewer who bought two—one placed horizontally for toys, the other vertically for display items.

Stitch a hem top and bottom and insert a rod in each, one to hang the divider from the ceiling and the other to add just enough heft so it won’t waft too much in a breeze.

Let the building blocks of style set your place apart—literally and metaphorically. This designer used chunky beech squares and rectangles to fashion a double-sided partition to separate a den from a dining room. The effect is warm and organic, yet modern and chic, and with solid construction it’s a lot more stable than the Jenga game it channels!

DIY a folding screen using discarded doors or shutters as panels. Stain, paint, or keep in as-found condition depending on your decor, then install hinges to connect panels.

Bring a sense of the outdoors in with a room divider fashioned from fallen tree branches. Insert branches (birch looks particularly beautiful) to a secure base, adding stones at the bottom to enhance the natural look, or twine with twinkling lights for a fairytale forest feel.
