Description

Flat panel display with multi-channel data transmission interface and image transmission method thereof

technical field

The present invention relates to a flat display and its image transmission method, and in particular to a flat display with a multi-channel data transmission interface and its image transmission method.

Background technique

Since the Austrian botanist F. Reinitzer discovered liquid crystals in 1888, liquid crystals have been widely used in people's daily life, such as digital cameras, computer screens, and televisions. Due to the slow reaction speed of liquid crystal molecules, various compensation techniques are generally used to compensate the flat panel display.

Please refer to FIG. 1 , which is a block diagram of a conventional flat panel display. The conventional flat panel display 10 includes an image processing circuit 110 and a display module 120 . The image processing circuit 110 includes a decoder 112 , a scaler (Scaler) 114 , a first memory controller 116 , a first memory 117 and a transmitter 118 . The decoder 112 is electrically connected to the scaler 114 . The scaler 114 is electrically connected to the transmitter 118 and the first storage controller 116 respectively. The first storage controller 116 is electrically connected to the first storage 117 .

The display module 120 includes an image driving circuit 130 , a second memory 140 , a data driver 150 , a display panel 160 and a scan driver 170 . The image driving circuit 130 includes a second storage controller 132 , a receiver 134 , a compensation driving unit 138 and a timing control 136 . The receiver 134 is electrically connected to the second storage controller 132 and the compensating driving unit 138 respectively. The second storage controller 132 is electrically connected to the second storage 140 and the compensation driving unit 138 respectively. The compensation driving unit 138 is electrically connected to the timing control unit 136 . The timing control unit 136 is electrically connected to the scan driver 170 and the data driver 150 respectively. The display panel 160 is electrically connected to the data driver 150 and the scan driver 170 respectively.

The receiver 134 of the display module 120 is connected to the transmitter 118 of the image processing circuit 110 , and there is a data transmission interface such as a serial low voltage differential signaling (LVDS) transmission interface between them. The image processing circuit 110 transmits images to the display module 120 through the serial low voltage differential signal transmission interface.

Furthermore, the decoder 112 receives an external video signal through the S terminal or the AV terminal, etc., decodes it to generate video data D, and the scaler 114 sequentially generates multiple frames of video data according to the video data D. When the scaler 114 generates the image data F(n-1) of the n-1th frame, the first storage controller 116 stores the image data F(n-1) of the n-1th frame in the first memory 117 , and the transmitter 118 transmits the image data F(n−1) of the n−1th frame to the receiver 134 . The second memory controller 132 also stores the image data F(n−1) of the n−1th frame in the second memory 140 .

Afterwards, when the scaler 114 generates the image data of the nth frame, the first storage controller 116 stores the image data F(n) of the nth frame in the first memory 117, and the transmitter 118 sends the nth frame The image data F(n) of is sent to the receiver 134 .

The compensation driving unit 138 receives the image data F(n-1) of the previous n-1th frame in the second memory 140 from the second storage controller 132, and receives the image of the current n-th frame from the receiver 134 The data F(n) is used to output the compensation driving data C to the timing control unit 136 . The timing control unit 136 outputs the compensation driving data C to the data driver 150 according to the timing, and outputs the scan start signal S to the scan driver 170 . The data driver 150 receives the compensation driving data C, and outputs the driving voltage CV to the display panel 160 accordingly, and the scan driver 170 receives the scan start signal S to sequentially control each row of pixels on the display panel 160 .

However, in order to enable the compensation drive unit 138 to obtain an appropriate overdrive control signal according to the previous frame and the current frame, the flat panel display 10 needs to have a second memory 140 configured in the display module 120 to store the image data of the previous frame At the same time, the second memory controller 130 needs to be specially configured in the image driving circuit 130 to control the second memory 140 to access data. Disposing the second memory 140 in the display module 120 not only increases the production cost, but also increases the area of the printed circuit board in the display module 120 relatively. In addition, disposing the second memory controller 130 in the image driving circuit 130 will require a relatively large number of pins for the image driving circuit 130 , and the package of the image driving circuit 130 cannot be effectively reduced.
