DMD control module characteristics:

One, colour consistency system:

Because of the material behavior of LED, the luminance of every LEDs there are differences.While how to guarantee to produce in enormous quantities, the consistance of every video machine on color is very important link.Our a set of software and hardware system brief introduction of exploitation is as follows:

At first require to determine preliminary Duty cycle, show colour gamut, brightness etc. according to characteristic, system power dissipation, the product Show Color of the RGB LED body used on ray machine.In conjunction with the LED driveability parameter adopted, all these data are inputed in the data model of building up in advance, computing obtains preliminary LED sequence simultaneously.The PCBA LED sequence that rear use obtains that returns, the some electronic bright bare engine is measured the light coordinate brightness value of actual displayed simultaneously under the state that shows RGB tri-pure colors and white with chroma meter.Again according to the needed parameter differences of actual measured value and expection, thereby the corresponding parameter of built data model is adjusted, export new LED sequence with the data model after adjusting again and drive ray machine to measure with chroma meter simultaneously, the parameters such as the actual light coordinate brightness value obtained like this can reach desired requirement gradually.

There is LED and various parts parameter characteristic deviation to some extent within the specific limits for when batch production, the data model of in data model, the deviate input being built, so just can obtain a lot of LED sequences, thus in theory when volume production arbitrary machine always can in the LED sequences database obtained, find suitable one group to reach same display effect when reality is exported.

In formal production, every machine can be done a calibration actions: measure the light coordinate brightness value under RGB tri-pure colors and white states with chroma meter, by a set of tool and tool software, adjust the LED electric current and select suitable LED sequence; Parameter that finally will be finally definite is cured in the storer of every machine intimate, can automatically record the corresponding measured value of luminance brightness sensor under each state simultaneously, during in order to follow-up automatic calibration, uses.

Annotate:

Duty cycle refers to each primary colours of RGB are opened in one-period unit interval sheet time and the ratio of whole unit interval sheet.The duty cycles sum of RGB tri-looks is 1.

LED sequence refers to what the display effect based on certain specific RGB duty cycle and expection generated, in order to the data sequence of periodic Control RGB LED switch.

Two: auto color/white balance correction:

After long-time use, each parts of projection computer (LED, main board elements etc.) can produce certain performance change, cause final display effect and the initial difference that produces; Thereby the skew of colour cast and the white balance point of color appears.

We are provided with the luminance brightness sensor in system, each LED luminance brightness of RGB of meeting real-time monitoring system, and contrasted with initial value, as departing from certain value, difference can be revised to reach the constant function of long-time use color.Working method is as follows:

Each start time luminance sensor light sensor can monitor the luminance brightness of each LED of RGA, and the raw data when dispatching from the factory compares, and draws the brightness number difference that the decay of LED lamp produces; Then automatically select by the software of special exploitation the data sequence be complementary with current LED characteristic.Also implanted LED monochrome information when software can record each shutdown automatically in system, and set up table list, data and Benchmark brightness value that when start shooting next time, system was transferred while shutting down last time are compared, if necessary, system will be adjusted the power supply of each LED lamp of RGA automatically to guarantee the consistent of white balance point.

The beneficial effects of the utility model:

A kind of all-in-one of the projection computer with the high performance operation system, projection size is at 40-120 cun, can complete any operation of general notebook computer, desktop computer, with functions such as wifi, bluetooth, 3G, 3D, can get online without being tethered to a cable, use the 3D glasses of outfit can see the 3D film; All-in-one top projection computer can disassemble independent use, conveniently goes out to carry.All-in-one is furnished with power amplifier, Hi-Fi sound-box is realized indoor movable home theater effect, and all-in-one can be equipped with high-capacity lithium battery, gives at ordinary times lithium cell charging, can accomplish Wireless in use; The operation of use wireless touchpad, facilitate easy-to-use.Due to the giant-screen of projection computer and portable unification, this kind of projection computer all-in-one designs for home entertaining specially.
