본 고안은 일반적인 텔레비전수상기로 입체영상을 시청하기 위해 왼쪽영상신호가 디스플레이되는 동안에 왼쪽액정안경만 투명하게 하고 또, 오른쪽영상신호가 디스프플레이되는 동안에 오른쪽 액정안경만 투명하게 할 수 있도록 된 입체화상장치의 시청용 액정안경구동회로에 관한 것이다.The present invention is a stereoscopic image that allows only the left liquid crystal glasses to be transparent while the left video signal is displayed for viewing stereoscopic images with a general television set, and the right liquid crystal glasses to be transparent while the right video signal is displayed. A liquid crystal glasses driving circuit for viewing of an apparatus is provided.
일반적으로 텔레비전수상기로 입체감을 만끽하면서도 입체영상을 시청하기 위해서는 별도의 입체화상장치가 필요하게 되는 바, 이러한 입체화상장치는 입체영상합성신호에서 분리된 수직동기신호를 이용하여 1필드씩 건너 왼쪽영상신호와 오른쪽영상신호를 번갈아 가면서 발생시킨후 상기 영상신호들은 텔레비전 수상기에서 수신되게 되고, 그에 따라 수신된 영상신호들은 텔레비전 수상기를 통해 송출되지만 정상적인 사람의 시각으로는 입체감을 느낄수 없게 된다.In general, a separate stereoscopic imager is required to watch a stereoscopic image while watching a stereoscopic image with a television receiver. Such a stereoscopic imager crosses a left image by one field using a vertical synchronization signal separated from a stereoscopic image synthesis signal. After the signal and the right video signal are generated alternately, the video signals are received by the television receiver, and thus the received video signals are transmitted through the television receiver, but the stereoscopic feeling cannot be felt by normal human vision.
즉, 왼쪽 및 오른쪽으로 구성된 액정안경을 통해서 텔레비전수상기를 시청하게 되면 왼쪽영상신호가 디스플레이 되는 동안에는 왼쪽액정안경만 투명하게 하고, 그 다음의 오른쪽영상신호가 디스플레이 되는 동안에는 오른쪽액정안경만 투명하게 되므로 입체영상에 대해 입체감을 느낄수 있는 것이다.That is, when viewing a television receiver through a liquid crystal glasses composed of left and right, only the left liquid crystal glasses are transparent while the left video signal is displayed, and only the right liquid crystal glasses are transparent while the next right video signal is displayed. You can feel the three-dimensional feeling of the image.
본 고안은 상기 왼쪽 및 오른쪽액정안경을 번갈아 구동시키기 위해 교변적으로 구동전원을 공급하므로써 입체영상을 시청할 수 있도록 된 입체화상장치의 시청용액정안경구동회로를 제공함에 그 목적이 있다.The object of the present invention is to provide a liquid crystal driving circuit for viewing of a stereoscopic image device that is capable of viewing stereoscopic images by alternately supplying driving power to alternately drive the left and right liquid crystal glasses.
이하 본 고안의 구성 및 작용 효과를 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 입체영상합성신호를 수직동기신호만 분리하게 되는 수직동기신호분리회로(1)와 왼쪽 및 오른쪽 액정안경을 판별하는 좌우필드판별회로(2), 복수개의 D형플립플롭(6∼8)과 앤드게이트(AD1), 인버터(IV1) 및 오아게이트 (OR1)로 구성되어 상기 수직동기신호와 판별신호를 이용하여 왼쪽 및 오른쪽 액정안경을 제어하는 제어신호발생회로(3) 및 상기 제어신호를 사용하여 선택되는 왼쪽 및 오른쪽액정안경으로 액정구동파형을 송출하는 아날로그멀티플랙서(4)(5)로 구비된 것을 특징으로 한 것이다.The present invention provides a vertical synchronous signal separation circuit (1) which separates a stereo synchronous signal only from a vertical synchronous signal, a left and right field discrimination circuit (2) for discriminating left and right liquid crystal glasses, and a plurality of D-type flip flops (6 to 8). ) And an AND gate AD 1 , an inverter IV 1 , and an OR gate OR 1 to control the left and right liquid crystal glasses using the vertical synchronization signal and the discrimination signal, and It is characterized in that it is provided with an analog multiplexer (4) (5) for transmitting the liquid crystal drive waveform to the left and right liquid crystal glasses selected using the control signal.
미설명 부호 VI는 입체영상합성신호, D와 Q 및는 D형플릅플롭의 입출력단,V1∼V3는 전원단, I0∼I4과 C1및 아날로그 멀티플랙서의 신호단, O1과 O2는 출력단을 나타낸다.Reference numeral VI denotes a stereoscopic composite signal, D, Q and Denotes the input and output terminals of the D-flop, V 1 to V 3 are the power supply terminals, signal terminals of the I 0 to I 4 and C 1 and analog multiplexers, and O 1 and O 2 are the output terminals.
제 1 도는 상기한 구조로 되어 있는 본 고안의 회로도로서, 입체영상합성신호(VI)가 수직동기신호분리회로(1)와 좌우필드판별회로(2)에 각각 공급되면 수직동기신호분리회로(1)에서는 제 2 도의 (2-1)과 같이 수직동기신호만 분리하게 되고, 또 좌우필드판별회로(2)에서는 필드의 오른쪽 및 왼쪽영상신호를 판별하는 신호가 "0" 및 "1"로써 제어신발생회로(3)에 송출되게 된다.1 is a circuit diagram of the present invention having the above-described structure. When the stereoscopic image synthesis signal VI is supplied to the vertical synchronous signal separation circuit 1 and the left and right field discrimination circuits 2, the vertical synchronous signal separation circuit 1 ), Only the vertical synchronization signal is separated as shown in (2-1) of FIG. 2, and in the left and right field discrimination circuit 2, signals for discriminating the right and left image signals of the field are controlled as "0" and "1". It is sent to the shoe life circuit (3).
그런데, 상기 입체영상합성신호(VI)는 신호특성상 왼쪽영상신호와 오른쪽영상신호가 각 수직동기신호간격으로 반복되게 되는데, 이는 1필드동안 왼쪽영상신호 다음 1필드동안 오른쪽영상신호가 반복되게 된다.However, in the stereoscopic image synthesis signal VI, the left image signal and the right image signal are repeated at each vertical synchronous signal interval due to the signal characteristic, which is the right image signal is repeated for one field after the left image signal for one field.
먼저 제 2 도의 (2-1)과 같이 수직동기신호는 출력단()이 입력단(D)에 연결된 D형 플립플롭(6)의 클록단에 공급되면 출력단(Q)()으로 제 2 도의 (2-2)와 (2-3)와 같은 신호와 D형 플립플롭(7)(8)의 클록단에 각각 공급되고, 그에 따라 D형 플립플롭(7)의 출력신호(Q)()는 (2-4)와 (2-5)와 같은 신호로써 아날로그 멀티플렉서(4)(5)의 신호단(C0)에 각각 공급되며, 또 D형 플립플롭(8)의 출력신호(A)()는 (2-6)와 (2-7)와 같은 신호로써 앤드게이트(AD1)(AD2)의 입력단에 각각 공급된다. 그러면, 전술한바 있는 좌우필드 판별회로(2)를 통한 "0" 및 "1"의 제어신호 발생회로(3)에 있는 인터버(IV1)와 앤드게이트(AD1)의 다른 입력단에 각각 공급되고, 그에 따라 앤드게이트(AD1)(AD2)의 출력신호가 오아게이트(OR1)를 통해 아날로그 멀티플렉서(4)(5)의 신호단(C1)에 각각 공급된다.First, as shown in (2-1) of FIG. 2, the vertical synchronization signal is output ( Is supplied to the clock terminal of the D flip-flop 6 connected to the input terminal D, and the output terminal Q ( Are supplied to the same signals as (2-2) and (2-3) of FIG. 2 and to the clock terminals of the D flip-flops 7 and 8, respectively, so that the output signals of the D flip-flops 7 are (Q) ( Are supplied to the signal terminals C 0 of the analog multiplexers 4 and 5, respectively, as signals (2-4) and (2-5), and the output signal A of the D flip-flop 8 is ) ( Are supplied to the input terminals of the AND gates AD 1 and AD 2 as signals (2-6) and (2-7). Then, the left and right field discrimination circuits 2 described above are supplied to the other inputs of the interleaver IV 1 and the AND gate AD 1 in the control signal generating circuits 3 of “0” and “1”, respectively. Accordingly, the output signals of the AND gates AD 1 and AD 2 are respectively supplied to the signal terminals C 1 of the analog multiplexers 4 and 5 through the ora gate OR 1 .
여기서 아날로그 멀티플렉서(4)(5)의 입력단(I0-I3)에는 3종류의 전원(V1-V3)은 공급되는데, 상기 전원(V1-V3)은 제어신호발생회로(3)의 출력신호가 신호단(C0)(C1)에 공급됨에 따라 표 1과 같이 변환된다.Here, three kinds of power supplies V 1 -V 3 are supplied to the input terminals I 0 -I 3 of the analog multiplexer 4, 5, and the power supplies V 1 -V 3 are the control signal generation circuit 3. As the output signal of) is supplied to the signal terminal C 0 (C 1 ), it is converted as shown in Table 1.
[표 1] 아날로그멀티플렉서(4)(5)의 신호 관계]Table 1 Signal Relationship of Analog Multiplexer (4) (5)]
상기 아날로그멀티플렉서(4)(5)의 입력신호(I0-I5)는 다음과 같이 설정되는 바, I0=V1, I1=I2=V2, I3=V3으로 설정되고, 여기서 V1〈V3로 되므로로 된다.The input signals I 0 -I 5 of the analog multiplexer 4, 5 are set as follows: I 0 = V 1 , I 1 = I 2 = V 2 , I 3 = V 3 , Where V 1 <V 3 It becomes
이때 아날로그멀티플렉서(4)(5)의 입력신호(V1-V3)는 제어신호발생회로(3)의 제어신호(C0)(C1)에 의해 제 2 도의 (2-8a)(2-8b)과 (2-9a)(2-9b)와 같은 신호가 출력단(O1)(O2)으로 송출되는 바, 먼저 상기 제어신호(C1)가 "O"인 오른쪽 영상신호로써 아날로그멀티플렉서(4)(5)에 공급되면(2-8a)의 신호가 출력단(O1)에, 또 (2-8b)의 신호가 출력단(O2)에 각각 공급되므로 좌측액정안경과 우측액정안경의 구동전압으로써 구동된다.At this time, the input signals (V 1- V 3 ) of the analog multiplexer (4) (5) are controlled by the control signals (C 0 ) (C 1 ) of the control signal generation circuit (2). -8b) and signals such as (2-9a) and (2-9b) are outputted to the output terminal O 1 (O 2 ). First, the control signal C 1 is an analog image as a right image signal with "O". When supplied to the multiplexer (4) (5) (2-8a) signal is supplied to the output terminal (O 1 ) and (2-8b) signal to the output terminal (O 2 ), respectively, the left liquid crystal glasses and the right liquid crystal glasses It is driven by the driving voltage of.
이와는 달리 제어신호발생회로(3)의 제어신호(C1)가 "1"인 왼쪽영상신호로써 아날로그멀티플렉서(4)(5)에 공급되면 (2-9a)의 신호가 출력단(O1)에, 또 (2-9b)의 신호가 출력단(O2)에 각각 공급되므로 좌측액정안경과 우측액정안경의 구동전압으로써 구동된다.On the contrary, when the control signal C 1 of the control signal generating circuit 3 is supplied to the analog multiplexer 4 and 5 as a left image signal having "1", the signal of (2-9a) is supplied to the output terminal O 1 . Since the signals of (2-9b) are respectively supplied to the output terminal (O 2 ), they are driven by the driving voltages of the left liquid crystal glasses and the right liquid crystal glasses.
여기서 좌우측액정의 특징은 액정전극양단에 V2전압을 중심으로 V1또는 V3전압이 가해지면 불투명하게 되고 또 V2전압이 가해지면 투명하게 된다.The characteristics of the left and right liquid crystal is made to about the voltage V 2 across the liquid crystal electrodes V 1 or V 3 When the voltage is applied again and the non-transparent V 2 voltage is applied to the transparent surface.
따라서, 출력단(O1)(O2)은 제 2 도의 (2-8a)(2-8b)와 (2-9a)(2-9b)를 각각 좌우측 안경의 액정에 가하면 1필드동안 왼쪽안경의 액정은 투명하게 되면서 오른쪽 안경의 액정이 불투명하게 되고, 따라서 다음 1필드동안 왼쪽안경의 액정은 불투명하게 되면서 오른쪽안경의 액정이 투명하게 되는 동작이 반복된다.Therefore, the output terminal O 1 (O 2 ) is applied to the liquid crystals of the left and right glasses by applying (2-8a) (2-8b) and (2-9a) (2-9b) of FIG. 2, respectively. The liquid crystal becomes transparent and the liquid crystal of the right glasses becomes opaque, so that the liquid crystal of the left glasses becomes opaque and the liquid crystal of the right glasses becomes transparent for the next one field.
그러므로, 전술한 바 있는 좌우필드판별회로(2)의 판별신호에 의해 왼쪽영상신호가 화면에 디스플레이되는 동안에는 왼쪽안경의 액정만 투명하게 되고, 이와 더불어 오른쪽영상신호가 화면에 디스플레이 되는 동안에는 오른쪽안경의 액정만 투명하게 되도록 조정되면 입체감을 느낄 수 있게된다.Therefore, the liquid crystal of the left eyeglasses becomes transparent while the left image signal is displayed on the screen by the discrimination signal of the left and right field discrimination circuits 2 described above, and the right eyeglasses are displayed while the right image signal is displayed on the screen. If the liquid crystal is adjusted to be transparent, you can feel a three-dimensional effect.
상기한 바와 같이 본 고안은 왼쪽 및 오른쪽 액정안경을 번갈아 구동시키기 위해 교번적으로 구동전원을 공급하므로써 입체영상을 시청할 수 있도록 입체화상장치의 시청용액정안경구동회로를 제공하는 것이다.As described above, the present invention provides a liquid crystal driving circuit for viewing of a stereoscopic image device so that stereoscopic images can be viewed by alternately supplying driving power to alternately drive left and right liquid crystal glasses.
