Displays used in handheld devices usually have the following salient features:

Portability:

The primary consideration for handheld devices is portability, so the display is often designed to be small, thin and light to accommodate the overall portability requirements of the device.

For example, tablets usually use LCD screens smaller than 10.4 inches, making them easy to hold and carry with one hand.

Display effect:

The displays of handheld devices generally pursue high definition, vivid colors and delicate picture quality to provide a high-quality visual experience.

AMOLED screens are widely used in handheld devices due to their bright colors, high brightness, and high contrast.

Touch function:

The display screens of almost all handheld devices are touch-enabled and support single or multi-touch to meet the user's interaction needs with the device.

Touch response speed is also an important performance indicator of the display screen, which directly affects the user experience.

Energy saving and battery life:

Handheld devices need to consider energy saving and battery life, so the displays often adopt low-power designs.

For example, the Mirasol screen consumes power only when the screen content changes and has low power consumption.

Durability:

Handheld devices often face various usage environments and unexpected situations, so the display needs to have high durability.

The scratch and impact resistance of the display is crucial to increasing the overall life of the device.

Intelligent control:

Some advanced handheld devices also support intelligent control functions, such as remote control, real-time content updates, etc.

These functions require the display to work closely with other hardware and software of the device to achieve a more intelligent and convenient user experience.

Adapt to the outdoor environment:

Handheld devices are often used outdoors, so the display needs to be able to display clearly under bright light. 

Both AMOLED screens and Mirasol screens have good display effects under strong outdoor light.

To sum up, the display screen used in handheld devices needs to have the characteristics of portability, excellent display effect, touch function, energy saving and battery life, durability and intelligent control. These features together constitute the core competitiveness of handheld device displays, providing users with a better and more convenient experience.
