DETAILED DESCRIPTION OF EMBODIMENTS

According to embodiments of the present disclosure, there are provided a data transmission method, a processor and a terminal device, which can save the costs of hardware and reduce power consumption for transmission.

Referring to FIG. 1, a data transmission method according to an embodiment of the present disclosure includes step 101 and step 102.

In step 101, RGB data are converted by a processor into Pentile data.

In the embodiment, the processor is capable of converting the RGB data into the Pentile data. In practice, the Pentile data include data of various pixel arrangements, such as Pentile RGB, Pentile RGW, Pentile RGBY.

In step 102, the Pentile data obtained after conversion are sent by the processor to a display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to a display system.

In the embodiment, the processor sends the Pentile data obtained after conversion to the display drive system, and the display drive system sends the drive signal, which is generated by converting the Pentile data, to the display system. The processor, the display drive system and the display system are configured in a same terminal device. In practice, the terminal device may include a handheld device, a television, a computer and the like.

It should be noted that the processor is a central processing unit (CPU) owned originally by the terminal device.

In the embodiment, the processor converts the RGB data into the Pentile data and sends the Pentile data obtained after conversion to the display drive system, and the display drive system sends the drive signal, which is generated by converting the Pentile data, to the display system. Thus, only the original processor of the terminal device is used for conversion without an additional chip, thereby saving the costs of hardware and reducing the power consumption for transmission.

For better understanding, the data transmission method according to the embodiment of the present disclosure is described with a specific example. Referring to FIG. 2, in a case that the Pentile data are Pentile data of RGB, a data transmission method according to an embodiment of the present disclosure includes step 201 to step 203.

In step 201, the RGB data are converted by the processor into Pentile data of RGB.

In the embodiment, the processor is capable of converting standard RGB data into Pentile data of RGB. An approach for the conversion may be found in the conventional technology, which is described herein.

In step 202, one color is selected by the processor from three different colors of sub-pixels contained in the Pentile data of RGB; and a pixel is generated by the processor by combining a sub-pixel of the selected one color serving as a common sub-pixel with a sub-pixel of each of two different unselected colors.

In the embodiment, the processor is capable of selecting one color from three different colors of sub-pixels contained in the Pentile data of RGB, and generating a pixel by combining a sub-pixel of the selected one color serving as a common sub-pixel with a sub-pixel of each of two different unselected colors. Multiple such pixels are generated from the Pentile data of RGB. In practice, the color for the common sub-pixel is selected randomly.

Reference is made to FIG. 3, which is a schematic diagram of an arrangement of RGB Pentile. In FIG. 3, each rectangle block represents a sub-pixel, and text in the rectangle block indicates a color of the sub-pixel. For example, if red color is selected as a color for a common pixel, a pixel (such as a pixel A shown in FIG. 3) is generated by combining a sub-pixel of red color with a sub-pixel of green color, and a pixel (such as a pixel B shown in FIG. 3) is generated by combining the sub-pixel of red color with a sub-pixel of blue color. In this way, the Pentile data of RGB is converted to data of pixels each consisting of a sub-pixel of red color and a sub-pixel of green color and pixels each consisting of a sub-pixel of red color and a sub-pixel of blue color.

In step 203, each of the generated pixels is sent by the processor to the display drive system.

In the embodiment, the processor sends each of the generated pixels to the display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to the display system.

The transmission rate for the processor to send the Pentile data of RGB to the display drive system is described by taking a mobile phone as an example hereinafter.

Assuming that the mobile phone is to display a high definition (HD) image of 720P transmitted through double channels of mobile industry processor interface (MIPI), the amount of data to be transmitted equals to 1280*720*2*8. If a frame rate is of 60, the transmission rate for the MIPI is of only 550 MHz. However, in the conversional technology, a processor has to transmit RGB data to an additional chip, and thus the amount of data of the same image to be transmitted with the same MIPI equals to 1280*720*3*8. If a frame rate is still of 60, the transmission rate for the MIPI is of 850 MHz. And then the Pentile data are transmitted from the additional chip to the display drive system. It can be seen from the comparison that the bandwidth for data transmission and the power consumption for transmission are reduced with the innovation.

In the embodiment, the processor converts the RGB data into the Pentile data of RGB, then selects one color from three different colors of sub-pixels contained in the Pentile data of RGB, generates a pixel by combining a sub-pixel of the selected one color serving as a common sub-pixel with a sub-pixel of each of two different unselected colors, and sends each of the generated pixels to the display drive system, and the display drive system sends the drive signal, which is generated by converting the Pentile data, to the display system. In this way, only two sub-pixels are transmitted to the display drive system at a time by the original processor of the terminal device, thereby not only saving the costs of hardware but also reducing the power consumption for transmission.

For better understanding, the data transmission method according to the embodiment of the present disclosure is described with a specific example. Referring to FIG. 4, in a case that the Pentile data are Pentile data of four primary colors, a data transmission method according to an embodiment of the present disclosure includes step 401 to step 404.

In step 401, the RGB data is converted by the processor into Pentile data of four primary colors.

In the embodiment, the processor is capable of converting the RGB data into the Pentile data of four primary colors. The Pentile data of four primary colors converted from the RGB data includes Pentile data of RGBW, Pentile data of RGBY and the like. In practice, the arrangement of RGBW is achieved by adding a white color on the basis of tricolor, and the arrangement of RGBY is achieved by adding a yellow color on the basis of tricolor.

In step 402, four different colors of sub-pixels contained in the Pentile data of four primary colors are classified by the processor into two groups.

In step 403, a pixel is generated by the processor using two sub-pixels of different colors in each of the two groups.

In the embodiment, the processor is capable of classifying the four different colors of sub-pixels contained in the Pentile data of four primary colors into two groups. In practice, the processor may select randomly two different colors to be grouped together.

Reference is made to FIG. 5, which is a schematic diagram of an arrangement of RGBW Pentile. In FIG. 5, each rectangle block represents a sub-pixel, and text in the rectangle block indicates a color of the sub-pixel. RGBW Pentile includes four colors, namely, red color, blue color, green color and white color. Assuming that blue color is grouped with white color while green color is grouped with red color, a pixel (such as a pixel C shown in FIG. 5) is generated using a sub-pixel of blue color and a sub-pixel of white color, and a pixel (such as a pixel D shown in FIG. 5) is generated using a sub-pixel of green color and a sub-pixel of red color.

Since the Pentile data of four primary colors include multiple sub-pixels, multiple such pixels may be generated.

In step 404, each of the generated pixels is sent by the processor to the display drive system.

In the embodiment, the processor is capable of sending each of the generated pixels to the display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to the display system.

The transmission rate for the processor to send the Pentile data of RGBW to the display drive system is described by taking a computer as an example hereinafter.

Assuming that the processor is to transmit an image of 2K4K RGB to the display system and the transmission rate is of 60 Hz, the transmission rate for the processor to transmit RGBW data to the display system is of only 8*106*2*8*60=7.6 Gbps. However, in the conventional technology, a processor has to transmit the RGB data to an additional chip. If the same image of 2K4K RGB is transmitted with the same transmission rate, the transmission rate is of 8*106*3*8*60=11.5 Gbps. And then the Pentile data are transmitted from the additional chip to the display drive system. It can be seen from the above that the power consumption for transmission is reduced with the innovation compared with the conventional technology.

In the embodiment, the processor converts the RGB data into the Pentile data of four primary colors, classifies four different colors of sub-pixels contained in the Pentile data of four primary colors into two groups, generates a pixel using two sub-pixels of different colors in each of the two groups, where multiple such pixels are generated from the Pentile data of four primary colors, and sends each of the generated pixels to the display drive system. In this way, only two sub-pixels are transmitted to the display drive system at a time by the original processor of the terminal device, thereby not only saving the costs of hardware but also reducing the power consumption for transmission.

A processor for performing the above data transmission method according to an embodiment of the present disclosure is described hereinafter. Reference is made to FIG. 6, which shows a basic logic structure of a processor according to an embodiment of the present disclosure. The processor includes a converting unit 601 and a sending unit 602.

The converting unit 601 is configured to convert RGB data into Pentile data.

The sending unit 602 is configured to send the Pentile data obtained after conversion to a display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to a display system.

The processor, the display drive system and the display system are configured in a same terminal device.

In the embodiment, the processor converts the RGB data into the Pentile data via the converting unit 601 and then sends the Pentile data obtained after conversion to the display drive system via the sending unit 602, and the display drive system sends the drive signal, which is generated by converting the Pentile data, to the display system. Thus, no additional chip is needed, thereby saving the costs of hardware and reducing the power consumption for transmission.

For better understanding of the above embodiment, data exchange between various elements included in the processor is described with a specific example. In a case that the Pentile data are Pentile data of RGB, referring to FIG. 7, a processor according to an embodiment of the present disclosure includes: a converting unit 701 and a sending unit 702.

The converting unit 701 includes a first converting sub-unit 7011.

The sending unit 702 includes a selecting and generating sub-unit 7021 and a first sending sub-unit 7022.

The first converting unit 7011 is configured to convert the RGB data into Pentile data of RGB and then send the Pentile data obtained after conversion to the selecting and generating sub-unit 7021.

The selecting and generating sub-unit 7021 is configured to, in a case that the Pentile data obtained after conversion are the Pentile data of RGB, select one color from three different colors of sub-pixels contained in the Pentile data of RGB, generate a pixel by combining a sub-pixel of the selected one color serving as a common sub-pixel with a sub-pixel of each of two different unselected colors, where multiple such pixels are generated from the Pentile data of RGB, and then send each of the generated pixels to the first sending sub-unit 7022. In practice, the color for the common sub-pixel is selected randomly. For example, if red color is selected as a color for a common pixel, a pixel (such as a pixel A shown in FIG. 3) is generated by combining a sub-pixel of red color with a sub-pixel of green color, and a pixel (such as a pixel B shown in FIG. 3) is generated by combining the sub-pixel of red color with a sub-pixel of blue color. In this way, the Pentile data of RGB is converted to data of pixels each consisting of a sub-pixel of red color and a sub-pixel of green color and pixels each consisting of a sub-pixel of red color and a sub-pixel of blue color.

The first sending sub-unit 7022 may send each of the generated pixels to the display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to a display system.

In the embodiment, the processor converts the RGB data into the Pentile data of RGB via the first converting sub-unit 7011. The selecting and generating sub-unit 7021, in a case that the Pentile data obtained after conversion are the Pentile data of RGB, selects one color from three different colors of sub-pixels contained in the Pentile data of RGB, and generates a pixel by combining a sub-pixel of the selected one color serving as a common sub-pixel with a sub-pixel of each of two different unselected colors, where multiple such pixels are generated from the Pentile data of RGB. The first sending sub-unit 7022 may send each of the generated pixels to the display drive system.

For better understanding of the above embodiment, data exchange between various elements included in the processor is described with a specific example. In a case that the Pentile data are Pentile data of four primary colors, referring to FIG. 8, a processor according to an embodiment of the present disclosure includes: a converting unit 801 and a sending unit 802.

The second converting sub-unit 8011 is configured to convert the RGB data into Pentile data of four primary colors, and then send the Pentile data obtained after conversion to the classifying sub-unit 8021. The Pentile data of four primary colors converted from the RGB data include Pentile data of RGBW, Pentile data of RGBY, and the like. In practice, the arrangement of RGBW is achieved by adding a white color on the basis of tricolor, and the arrangement of RGBY is achieved by adding a yellow color on the basis of tricolor.

The classifying sub-unit 8021 is configured to, in a case that the Pentile data obtained after conversion are the Pentile data of four primary colors, classify four different colors of sub-pixels contained in the Pentile data of four primary colors into two groups, and then send the classification result to the generating sub-unit 8022. In practice, the processor may select randomly two different colors to be grouped together.

The generating sub-unit 8022 is configured to generate a pixel using two sub-pixels of different colors in each of the two groups. Since the Pentile data of four primary colors include multiple sub-pixels, multiple such pixels may be generated. Then the generating sub-unit 8022 sends the generated pixels to the second sending sub-unit 8023.

Reference is made to FIG. 5, which is a schematic diagram of an arrangement of RGBW Pentile. In FIG. 5, each rectangle block represents a sub-pixel, and text in the rectangle block indicates a color of the sub-pixel. RGBW Pentile includes four colors, namely, red color, blue color, green color and white color. Assuming that blue color is grouped with white color while green color is grouped with red color, a pixel (such as a pixel C shown in FIG. 5) is generated using a sub-pixel of blue color and a sub-pixel of white color, and a pixel (such as a pixel D shown in FIG. 5) is generated using a sub-pixel of green color and a sub-pixel of red color.

The second sending sub-unit 8023 sends each of the generated pixels to a display drive system, and the display drive system sends a drive signal, which is generated by converting the Pentile data, to a display system.
