Background technology
Fast gate-type (being called active again) 3D LCD TV need send synchronizing signal to the 3D glasses so that the right and left eyes image synchronization that the right and left eyes switch of glasses and TV show, because the factor of self 3D image-forming principle also needs to adopt backlight subarea to scan to avoid the right and left eyes picture crosstalk.
Traditional fast gate-type 3D LCD TV backlight subarea-scanning module is integrated on liquid crystal display screen or the power panel, and the 3D synchronizing signal generally adopts infrared ray to transmit, and offers expelling plate after finishing infrared coding by movement master chip or coding chip.The 3D synchronizing signal adopts the mode of master chip coding to be subjected to the functional limitation of master chip own, adopts external coding chip mode then to increase the complexity of extra cost and movement circuit.
The utility model content
Weak point at the prior art existence, the purpose of this utility model is to provide a kind of output loop system of scanner uni 3D synchronizing signal coding backlight, this system can finish the output circuit circuit system of backlight subarea sweep signal and the output of 3D synchronizing signal coding simultaneously, and has advantages such as versatility height and low cost of manufacture.
The purpose of this utility model is achieved through the following technical solutions:
A kind of output loop system of scanner uni 3D synchronizing signal coding backlight, mainly be made up of with the mixed signal micro-control processor that is connected with master chip master chip, described mixed signal micro-control processor is connected with power panel scanning drive chip backlight and 3D synchronizing signal expelling plate respectively.
In order to realize the utility model better, pass through I between described master chip and the mixed signal micro-control processor
2The C bus connects, and master chip passes through I
2C bus protocol and mixed signal micro-control processor carry out data interaction, and the mode of operation of control mixed signal micro-control processor; Also be connected with adjusting PWM data wire backlight between described master chip and the mixed signal micro-control processor.
As preferably, described master chip is connected with liquid crystal display screen, and liquid crystal display screen also is connected with the mixed signal micro-control processor.
The utility model is compared than prior art, has the following advantages and beneficial effect:
The utility model has been designed the circuit that can finish backlight subarea sweep signal and the output of 3D synchronizing signal coding simultaneously, has advantages such as versatility height and low cost of manufacture.This circuit system can be realized the 2D of television set liquid crystal display screen and the demonstration of two kinds of mode of operations of 3D, can scan two kinds of display effects of 2D and 3D expeditiously.

Be described in further detail below in conjunction with the utility model of embodiment:
Embodiment
As Fig. 1～shown in Figure 2, a kind of output loop system of scanner uni 3D synchronizing signal coding backlight mainly is made up of with the mixed signal micro-control processor 2 that is connected with master chip 1 master chip 1.Mixed signal micro-control processor 2 is connected with power panel scanning drive chip 5 backlight and 3D synchronizing signal expelling plate 4 respectively.
Pass through I between master chip 1 and the mixed signal micro-control processor 2
2The C bus connects, and master chip 1 passes through I
2C bus protocol and mixed signal micro-control processor 2 carry out data interaction, and the mode of operation of control mixed signal micro-control processor 2.Also be connected with adjusting PWM data wire backlight between master chip 1 and the mixed signal micro-control processor 2.
There are two kinds of mode of operations in a kind of output loop system of scanner uni 3D synchronizing signal coding backlight, is respectively 2D pattern and 3D pattern.
Under the 2D pattern, the adjusting pwm signal backlight that mixed signal micro-control processor 2 receives by master chip 1 output is transmitted to power panel scanning drive chip 5 backlight with this signal.Control the lamp bar of whole backlight subarea by power panel scanning drive chip 5 backlight simultaneously according to this signal, in order to liquid crystal display screen 3 integrally-regulated its backlight illuminations.
Under the 3D pattern, the synchronizing signal that mixed signal micro-control processor 2 receives by liquid crystal display screen 3 outputs.The synchronizing signal that mixed signal micro-control processor 2 is exported liquid crystal display screen 3 by internal processes control is encoded to infrared sign indicating number and delivers to 3D synchronizing signal expelling plate 4.To power panel scanning drive chip 5 backlight, the latter is according to the bright subarea-scanning effect that secretly reaches of each backlight subarea lamp bar of this signal controlling according to subregion order output scanning signal successively for the backlight subarea of mating this synchronizing signal simultaneously and dividing according to liquid crystal display screen 3.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
