Abstract
The utility model discloses light emitting diode (LED) display equipment which comprises a data acquisition unit, a data conversion unit and an LED display unit, wherein the data acquisition unit is used for obtaining image color data, and the data acquisition unit is a digital signal processing (DSP) chip; the data conversion unit is connected with the data acquisition unit and used for enabling the image color data obtained by the data acquisition data unit to carry out data conversion, and the data conversion unit is a general programmable processor central processing unit (CPU); and the LED display unit is connected with the data conversion unit and enables data after conversion through the data conversion unit to be displayed, the LED display unit is formed by a plurality of LED luminous units, and the LED luminous units are formed by red LEDs, green LEDs, blue LEDs, and white LEDs. Due to the structure, the LED display equipment sufficiently utilizes combination of LEDs in four colors, and reduces power consumption.
Description
Technical field
The utility model relates to display device, relates in particular to the display device that adopts LED.
Background technology
In at present popular light-emitting diode display, the LED fluorescent tube that adopts mainly comprises two types: 1. it is next luminous that the light-emitting diode display of cheapness adopts one or more white light LEDs usually, when needs display color data, shows different colors by colored filter.The display cost of this structure is lower, and is true not but color shows, owing to using optical filter usually the situation of cross-color can occur, still because the white light LEDs power consumption is low, has advantages of the power consumption of saving; 2.RGB primitive colours LED, the LED of this structure does not need to use optical filter, and the light of LED can directly be incident upon on the demonstration face glass and demonstrate the color that needs, so color is pure, and colour gamut is wide.But the display of this structure faces another kind of defective: in most of the cases, most of zone that face glass need to show is all white, therefore three kinds of luminous lamp tubes of RGB of primitive colours LED are all lighted in the overwhelming majority uses fully, form white by three kinds of blend of colors of RGB, this can cause great energy consumption, causes energy dissipation.
The utility model content
For the defective of prior art, the utility model discloses a kind of LED display device, the color reduction can not only be effectively guaranteed accurately, and energy resource consumption can be reduced.
For achieving the above object, the utility model is achieved through the following technical solutions:
The LED display device comprises that be used to the data acquisition unit that obtains the image color data described data acquisition unit is dsp chip; The Date Conversion Unit that is used for the image color data that data acquisition unit obtains are carried out data-switching that is connected with data acquisition unit, described Date Conversion Unit is general purpose programmable processors CPU; The LED display unit that is connected with Date Conversion Unit and the data after Date Conversion Unit conversion are shown, described LED display unit comprises a plurality of LED flat light emissions, and described LED flat light emission is comprised of red light emitting diodes, green LED, blue LED and white light-emitting diode.
Said structure carries out work in the following way: the color data of the image that data acquisition unit dsp used obtains, Date Conversion Unit CPU used is that different color datas carries out assignment, for example red corresponding to 20% gray scale, green corresponding to 40% gray scale, blue corresponding to 15% gray scale etc., this image color collection and gradation conversion algorithm are very ripe in image processing field, have had multiple different algorithm can be used for realizing this color collection and gradation conversion.Due to dsp, cpu be can program storage processor, therefore can adopt different algorithms according to the difference of application.
After completing above-mentioned data-switching, the cpu resulting color gray-scale value of output and white value, export to LED display unit, different colours LED lighting in the driving LED display unit, because the white light LEDs energy consumption is low, the luminescence efficiency of white light-emitting diode is far longer than the luminescence efficiency of redness, green, blue LED, and major part is white in the color that will show, therefore White LED is to replace other primitive colours LED to light as a rule, effectively reduces power consumption; When showing monochrome image, White LED does not work simultaneously, and this moment, display had for the illumination effect of colour the illumination effect that the RGB three primary display has, and color is pure; When including red, green, blue three colouring component in the view data that shows, White LED just can be lighted the colour mixture that replaces R, G, B diode to form.
By such scheme, realized the overall equilbrium of energy consumption and color displays quality.
Wherein, described LED display unit also comprises display driver circuit, is used for driving the control flat light emission luminous, and this is apparent to those skilled in the art.
Further, the applicant by statistical combination versicolor display frequency in most cases, thereby drawn following optimum combination, described LED flat light emission is comprised of a red light emitting diodes, a green LED, a blue LED and two white light-emitting diodes.
In sum, display device of the present utility model adopts four look light emitting diodes to form pixel, utilizes the white light that white light-emitting diode sends to replace mixing by RGB the white light that forms; Reduce energy consumption, saved the energy, guaranteed again colored display quality simultaneously.

Fig. 1 is the structural representation of the utility model display device;
Fig. 2 is the structural representation of the LED display unit of the utility model display device.
Embodiment
With reference to figure 1, LED display device of the present utility model comprises: data acquisition unit is used for obtaining the image color data; Date Conversion Unit, the connection data collecting unit carries out data-switching with the view data that data acquisition unit obtains; LED display unit, the connection data converting unit shows the data after the Date Conversion Unit conversion.
With reference to figure 2, LED display unit is comprised of the display driver circuit of a plurality of LED flat light emissions and driving flat light emission, and wherein each LED flat light emission comprises that a red light emitting diodes, a green LED, a blue LED and two white light-emitting diodes form.
Above combination is only a specific implementation of the present utility model, does not limit actual LED number, has only illustrated to form the colour type of single pixel, and the number combination of other LED can be set as required.
The above is only this novel preferred embodiment, does not consist of special restriction, any modification of carrying out based on the present utility model spirit, is equal to and replaces and improvement etc., within all should being included in the novel protection domain of this use.
