Smartphones are can be extremely useful devices to own. The LCD screen is an integral part of the display system of a smart device, including those for iPhone 5s cell phones.

Understanding what LCD technology is and how it functions can be helpful for purchasing the proper smartphone components and installing them correctly.

Display quality: LCD stands for Liquid Crystal Display. LCD technology is common in computers, tablets, and other smart devices such as the iPhone 5s.

Power use: LCD makes it possible for displays to be thinner and lighter. These screens consume much less power than LED or gas displays. They work using a principle that blocks light instead of emitting it.

Matrix grid: LCD display screens are made with a passive or active matrix that displays a grid. The matrix is known as a TFT when active, and a passive matrix has a grid of conducting pixels that intersect on the grid. The iPhone generally uses an active matrix, which helps increase color saturation.

Dirt: Dirt, grime, and other oils may have made their way into your LCD system. This can also interfere with the way your device works and can be solved by screen replacement.

Option 2: An iPhone 5s requires a specific type of LCD display touch screen. Any touch screen that you purchase should specify which devices it will work properly with.

With screens virtually everywhere, monitoring a child"s screen time can be challenging. To complicate matters, some screen time can be educational and support children"s social development. So how do you manage your child"s screen time? Here"s a primer on guiding your child"s use of screens and media.

By age 2, children may benefit from some types of screen time, such as programming with music, movement and stories. By watching together, you can help your child understand what he or he is seeing and apply it in real life. However, passive screen time shouldn"t replace reading, playing or problem-solving.

The American Academy of Pediatrics discourages media use, except for video chatting, by children younger than 18 months. If you introduce digital media to children ages 18 to 24 months, make sure it"s high quality and avoid solo media use. For children ages 2 to 5, limit screen time to one hour a day of high-quality programming.

Encourage your child to think critically about what they see on their screens. Ask your child to consider whether everything on the internet is accurate. Does your child know how to tell if a website is trustworthy? Help your child understand that media are made by humans with points of view. Explain that many types of technology collect data to send users ads or to make money.

You"ll likely need to continue to guide, manage and monitor your child"s use of screens and media as he or she grows. But by developing household rules — and revisiting them as your child grows — you can help ensure a safe experience.

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.

This is a new Pi Pico display from Waveshare with many more pixels. It is a 2inch LCD display module, designed for Raspberry Pi Pico, with an embedded ST7789VW driver, 65K RGB colours, 320x240 pixels and an SPI interface. A Pi Pico can be plugged into the rear of the screen for very easy connection without any soldering. It sports 4 simple button switches for user input. It is bright, colourful and easy to program. The makers supply an example program (see below), which includes the display driver, making it very easy to get started. The manufacturer"s wiki can be found at:
