1. COF (Chip-on-Film) In-Cell LCDs:

   • Definition: COF technology involves bonding the driver IC (integrated circuit) directly to a flexible film (FPC) rather than adhering it to the glass.
   • Advantages:
     • Ultra-Narrow Frame: COF reduces the width of the frame, making it easier to achieve an ultra-narrow bezel.
     • Space Efficiency: The reserved area on the panel is smaller due to the FPC, allowing for a more compact design.
     • High Yield and Stability: COF has mature processes, stable product quality, and high production yield.
   • Considerations:
     • Increased FPC Complexity: COF requires additional FPC components, which can impact cost and manufacturing complexity.
     • Higher Packaging Temperature: COF places higher process requirements due to elevated packaging temperatures.
     • Cost: Currently, COF may be more expensive than other solutions.

2. COG (Chip-on-Glass) In-Cell LCDs:

   • Definition: COG technology bonds the driver IC directly to the glass substrate.
   • Advantages:
     • Thin and Light: COG can create thin and lightweight LCD screen assemblies.
     • Stable Product Quality: COG has a mature process, resulting in stable product quality and high yield.
     • Cost-Effective: COG is relatively low-cost and widely used.
   • Considerations:
     • Limited Ultra-Narrow Frame Capability: COG may not achieve the same ultra-narrow frame as COF.
     • Compatibility with Original Designs: COG is suitable for devices originally designed with LCDs.
     • Battery Impact: LCDs consume more power than OLEDs.

In summary, both COF and COG In-Cell LCDs offer unique advantages and considerations. The choice depends on design requirements, cost considerations, and compatibility with existing hardware. As technology evolves, manufacturers continue to refine these display technologies to enhance user experiences.

So far we could not get after market iPhone 14 screens but good news now few manufacturers in China have successfully made INCELL versions of iPhone 14 after market display screens. Currently we are taking pre-order bookings for iPhone 14 LCD screens.

in-cell LCD display is a type of screen technology that integrates the touch sensor layer directly into the LCD layer. This allows for a thinner, lighter, and more responsive display, as well as a more seamless overall design. In-cell LCD displays are also known for their excellent color accuracy and wide viewing angles.

There are four types of iPhone LCD Screens avilable in the market.
1. Original / OEM
2. Soft OLED
3. Hard OLED
4. Incell (Budget option)

1. ORIGINAL / OEM
These screens are original from Apple or original with refurbished touch screen.

2. SOFT OLED
Soft OLEDs are made of a flexible plastic substrate, which is why they last longer than Hard OLEDs. They are much more resistant to impact.
Plastic is also a better thermal insulator than glass. These various factors mean that a soft OLED will tend to age (develop burn-in) more rapidly than a similar hard OLED.
Remember original Apple screen is Hard OLED. Spoft OLED is 1:1 same size as original. SOFT OLED is more resillent to breakage. Its more expensive
than HARD OLED.

3. HARD OLED

Hard OLEDs are manufactured using a glass substrate. it is more physically fragile and easy to break. Due to the design of the phones and material limitations of the hard OLED, there is a slightly larger border between the bottom of the display and the bottom of the frame.
Its Lower-priced option, Reliable manufacturing process, Somewhat resistant to screen burn-in.

4. INCELL

TFT In-cell displays are revolutionary in the sense that they combine a digitizer, use touch input, and integrate an LCD screen into a single-layer display. Some reports also suggest that in-cell technology displays provide better resolution compared to standard LCD screens.
In-cell technology may also be called in-cell touch technology. The term in-cell display emerged in 2012 in reports that Apple's successor to the iPhone 4S would include this new technology, thus reducing the thickness of the screen.
Less advanced touchscreen devices, including many smartphones and tablets, tend to have two separate display layers that need to be combined internally. The digitizer is used for touch sensitivity while the LCD screen displays the on-screen images. In-cell display technology combines these layers into a single layer, allowing devices to be thinner and lighter.
In-cell screens are stable screens, because they are a single element rather than separate glued components. In addition, no raster lines are visible, and the image resolution is higher than with standard LCD screens. Brightness is not as high as OLED Screens but price wise this is a cheaper option.

When you buy a used iPhone, you have no idea, if it has original screen. Its quiet easy to check.

Tap General > About. Here, you'll be able to see PARTS AND SERVICE HISTORY under your iPhone's general information. Under this, you'll see Display. If your screen was replaced using parts verified by Apple, “Genuine Apple Part” will show up next to it. 

If its a non genuine screen or genuine from another phone, it will show as " unknown part". 

Anothe way is to turn the brightness all the way up and compare it with another iphone of the same model with full brightness. you will notice original screen much more brighter than the copy screen. (Only valid for iPhone 11 Pro, 12, 13 & 14). 

iPhone 11 Pro LCD screen has 900 nits of brightness and iPhone 14 Pro Max screed has about 2000 nits of brightness.
