Honor Magic 4 is a mobile phone product released by Honor Company in Barcelona on February 28, 2022.

Honor Magic 4 is equipped with Qualcomm Snapdragon 8 Gen1 processor; rear 50-megapixel wide-angle lens, 50-megapixel ultra-wide-angle lens, 8-megapixel 50x periscope telephoto lens, and front-facing 12-megapixel ultra-wide-angle lens; built-in 4800mAh capacity battery.

The front entrance of Honor Magic 4 is equipped with a 6.81-inch curved flexible OLED screen, which adopts a central star ring design and is overall rounded. The back cover has a four-curved design, the frame is made of silver metal, and the middle frame is centered on the speaker. The infrared is designed on the left side and the microphone is designed on the right side.

Performance

Honor Magic 4 is equipped with Snapdragon 8 Gen1 processor, using 4nm process, and the CPU uses Cortex- The X2 ultra-large core has a theoretical performance that is 20% higher than the Snapdragon 888, and the GPU performance is also 30% higher than the previous generation.

Heat dissipation

Honor Magic 4 uses superconducting hexagonal graphene and ultra-thin VC liquid cooling. The thermal conductivity is 50% higher than the first generation graphene technology, while also achieving heat dissipation. And thin.

Screen

Honor Magic 4 achieves the coexistence of 1920Hz dimming frequency and LTPO screen material through BOE Screen’s exclusive screen driver chip. Bringing lower brightness fluctuations, which can reduce eye pressure under low brightness. It supports LTPO adaptive variable refresh rate feature. When the system interface is slid, the refresh rate will be maintained at 90Hz. After 3 seconds when the hand is removed, it will quickly reduce to 10Hz to save power.

Extended knowledge: infrared remote control

Remote control technology is also called remote control Technology refers to the remote control of controlled targets and is widely used in the fields of industrial control, aerospace, and home appliances.

Infrared remote control is a wireless, non-contact control technology. It has significant advantages such as strong anti-interference ability, reliable information transmission, low power consumption, low cost, and easy implementation. It is used by many electronic devices, especially household appliances. It is widely adopted and increasingly used in computer and mobile phone systems.

The transmitting circuit of the infrared remote control uses infrared light-emitting diodes to emit modulated infrared light waves; the infrared receiving circuit is composed of infrared receiving diodes, triodes or silicon photovoltaic cells, which convert the infrared light emitted by the infrared transmitter into corresponding The electrical signal is then sent to the post amplifier.

• Transmitters generally consist of command keys (or operating levers), command encoding systems, modulation circuits, drive circuits, and transmitter circuits. When the command key is pressed or the operating lever is pushed, the command coding circuit generates the required command coding signal. The command coding signal modulates the carrier wave, and then is power amplified by the driving circuit and then emits the modulated command code outward from the transmitting circuit. Signal.

• The receiving circuit is generally composed of a receiving circuit, an amplifying circuit, a modulating circuit, an instruction decoding circuit, a driving circuit, and an execution circuit (mechanism). The receiving circuit receives the modulated coded command signal sent by the transmitter, amplifies it and sends it to the demodulation circuit, which demodulates the modulated command coded signal, that is, restores it to a coded signal. The instruction decoder decodes the encoded instruction signal, and finally the driver circuit drives the execution circuit to realize the operation control (mechanism) of various instructions.
