Display characteristics

1, using the most advanced international 65536 ( 16bit ) gray scale control technology, completely solve the full-color display in the low gray scale display when the mosaic phenomenon, so that the displayed image natural transition, delicate, bright colors, PLC Lamp the full realization of video source of truth.

In 2, the display contrast to 6400:1, so that the displayed image hierarchy, overcomes the full-color display by luminance changes impact.

In 3, the display color can achieve 281.5 trillion, fully meet the various advanced video source input requirements, can display the perfect color.

4, the virtual pixel display, the display size under the same circumstances, than ordinary LED display resolution is increased by 4 times, so that the Dimmer Switch dab5d58ck display can display the incomparable fine image.

In 5, the drive plate gray scale control technology, the nonlinear correction function integrated into the drive plate chip, using 65536 ( 16bit ) gray scale correction technology, greatly improving the data transmission rate, and improve the system stability, nonlinear correction way to drive LED tube, so that LED display screen adaptation of human nonlinear demand, thus showing was born vivid video screen, online.upspowermanufacturer.com the image more stable.

6, using Gigabit wire transmission technology and board level gray processing technology, so that the data transmission speed is greatly improved, so the 8 display scanning frequency can reach 1200Hz, eliminates the LED screen flicker phenomenon, eliminate the fatigue of the human eye viewing, the maximum to meet the needs of digital equipment.

7, using a constant current driving circuit, ensure the LED luminous tube is stable, reliable, and extension of the LED luminous tube service life, but also ensures that the LED luminous tube luminance uniformity.

8, through the software implementation on the LED display the entire screen and each unit module brightness, contrast adjustment, google tv remote with memory function, ensure the display brightness of the entire screen consistency.

9, using point-by-point brightness control technology, can ensure the uniformity of LED display screen, the screen after several years running, LED LED brightness will appear in varying degrees of attenuation, using point-by-point brightness adjustment technology takes only two hours to let the screen back to the factory when the homogeneous state.

10, the system redundant technology, can realize the system scan controller with two-way data transmission, wherein a scan controller is damaged or level wiring fault does not affect the whole screen display.

power consumption

Linear voltage regulator switch voltage will face problem of power consumption, switch mode has the problems of noise, LED drive the choice of conversion depends on the application.

How to convert?

The linear regulator to convert the voltage will face the problem of power consumption, LED Spotlight this approach is more suitable for the need to avoid noise ( such as car audio ) and therefore cannot use switch mode converter. While the switch mode is characterized by a very high conversion efficiency, but it also has the problems of noise, LED Floodlight so the choice of conversion depends on the application.

Usually, the charge pump drive efficiency with the input voltage changes, the change in voltage range applications, its efficiency is quite low; and the voltage variation range of small applications, only when the input and output voltages are integral multiples of relations, its efficiency can reach the maximum, but this in battery powered applications it is difficult to achieve. The inductance of the conversion efficiency is not affected by voltage interference, application limits than the charge pump is less, so the current conversion circuit with inductance mode.

How to evaluate the performance?

Say objectively, evaluation of HB LED drive IC performance according to different applications, can lump together. Such as decorative lighting applications on the RGB color change control requirements, the performance becomes the main index, in monochrome application does not require the. And as the narrow space of application requirements is the heat capacity; LED Candle Bulb automotive lighting instead of application requirements of both the original circuit system and smooth combination of performance and high reliability is required; in NB and display applications, the string LED brightness balance control driver IC for each branch current is accurate control, such as MAXIM product control precision can reach 3%; projector application requires high efficiency driving circuit, the rapid adjustment of brightness and thermal protection capability; in alternative applications, performance more is reflected throughout the programme rather than a single driver on IC. In general, the integration of device, control volume, speed of response, fault diagnosis, heat-resistant are performance evaluation.

Usually, high integration aims to improve performance, but at high power, high integration as the meet the current will increase in chip area, increase the cost at the same time also faces the problem of heat dissipation, so, how to balance the power and integration is the relationship between the driver IC design task. Drive IC in improved chip technology to meet the cost at the same time, improve the package to solve the problem of heat dissipation.
