Better display the details of each part of the image.

The color engine control system 100 can control the operational state of the color engine 15 based on the content displayed on the display 13. For example, when the data displayed by the display 13 is plain text format material that does not include image format data, the color engine control system 100 can turn off the color engine 15 to reduce power consumption. When the data displayed by the display 13 is image format data, the color engine control system 100 can activate the color engine 15 to perform color parameter adjustment on the image format data to obtain a clear and sharp image effect. Alternatively, when the data displayed on the display 13 has both image format data and text format data, the color engine control system 100 can control the color engine 15 to perform color parameter adjustment only on the image format data portion. Color parameter adjustment is not performed on text format data, which effectively controls the energy consumption generated by the color engine. In this embodiment, the color engine control system 100 includes a display data acquisition module 101, a display data analysis module 102, and a color engine control module 103. Above Each function module of 101-103 can be stored in the memory 11 in the form of a software program, a firmware, or an application, and the processor 12 controls the execution of each function module. In addition, each function module included in the color engine control system 100 can be directly implanted in the operating system of the electronic device 1, or can be directly installed in the memory 11 and controlled by the processor 12. Further, the color engine control system 100 may also be a firmware program built into the processor 12 for achieving a predetermined function. At this time, the processor 12 built with the color engine control system 100 may be a drive IC of the display 13 to drive the display 13 for display.

The display data acquisition module 101 is configured to acquire information to be displayed on the display 13 . Preferably, in this embodiment, the to-be-displayed data refers to the next frame of data of one frame of data currently displayed by the display 13. In other embodiments, the to-be-displayed data may also refer to two or more frames of data after one frame of data currently displayed by the display 13.

Specifically, please participate in FIG. 2, which is an equivalent circuit diagram of the display 13. The display 13 includes a plurality of gate lines GL (also referred to as "scan lines") parallel to each other, a source line SL (also referred to as "data line") perpendicular to and insulated from the gate line GL, and a gate driver 131. The source driver 132 and the timing controller 133. Wherein, the gate line GL extends in a first direction (for example, a lateral direction), and the source line SL extends in a second direction (for example, a longitudinal direction). The gate line GL intersects the source line SL to define pixel units arranged in a matrix.

The timing controller 133 is configured to output a gate control signal to the gate driver 131 and output a source control signal and display data to the source driver 132. The gate driver 131 is connected to the pixel unit through the gate line GL. The gate driver 131 outputs a gate signal (also referred to as a "scanning signal") to the pixel unit through the gate line GL to strobe the corresponding picture Prime unit. The source driver 132 is connected to the pixel unit by the source line SL, and transmits the display data to the pixel unit through the source line SL for display. Therefore, in an embodiment, the display data acquisition module 102 can obtain the data to be displayed of the display 13 from the timing controller 133.

The display data analysis module 102 is configured to analyze the acquired data to be displayed, and determine whether the data to be displayed has image format data. Specifically, the image format data includes dynamic image format data (eg, animation, video, etc.) and still image format data. In an embodiment, the display data obtained from the timing controller 133 may be a sequence of digital data, and the display data analysis module 103 directly decodes the digital data to obtain the digital data. Whether to include image format data.

In other embodiments, the display data acquisition module 101 can directly capture the display data directly from the display screen output by the display 13. At this time, the display data analysis module 102 can identify the text portion and the image portion of the display data by using an image recognition technology (OCR) to determine whether the display material includes image format data. In addition, it is also possible to determine whether the display material contains image format data according to the application software installed in the electronic device 1. For example, the display data module 102 can detect whether the electronic device 1 opens a text editor such as a notepad, a WORD, a text editor (VIM), or the like to determine whether the display material includes image format data. When it is detected that the similar text editing software is turned on, the display data analysis module 102 determines that the display data does not include the image format data, thereby turning off the color engine 15. At the same time, the text editing software may actively notify the display data analysis module 102 that the currently displayed data is text format data when the text editing software is turned on. Alternatively, it is also possible to automatically discriminate whether the display material includes image format data by the drive IC of the display 13 according to the above method.

The color engine control module 103 is configured to control the working state of the color engine 15 according to the analysis result of the data to be displayed by the display data analysis module 102. Specifically, if the data to be displayed has no image format data, it indicates that the data to be displayed is text format data, and the color parameter adjustment of the color engine 15 is not needed. At this time, the color engine control module 103 disables the data. Color engine 15 to save energy. Specifically, the color engine control module 103 can generate a first control command and send it to the color engine 15 through the processor 12 to control the color engine 15 to be in a closed state. On the other hand, if the data to be displayed has image format data, the color engine control module 15 enables the color engine 15 to perform color parameter adjustment on the data to be displayed. After the color parameter adjustment is performed on the data to be displayed, the display 13 can be directly displayed through the display 13 according to the display timing of the display 13. At the same time, if the data to be displayed does not need to be adjusted by the color parameter, the display 13 is also displayed according to the display timing. Specifically, when the to-be-displayed data has image format data, the color engine control module 103 can generate a second control instruction and send it to the color engine 15 through the processor 12 to control the color engine 15 to be in an activated state. .

In another embodiment, in the case that the data to be displayed has image format data, the display data analysis module 102 may further use the graphic recognition technology to identify the text portion and the image in the data to be displayed. The image portion is then sent to the color engine control module 103. The color engine control module 103 controls the color engine 15 to perform color parameter adjustment on the image portion according to the recognition result, and does not perform color parameter adjustment on the text portion to achieve better energy saving effect. For example, the color engine control module 103 can directly display the text format data through the display 13 according to the display timing of the data to be displayed, and transmit the image format data to the color engine 15 for color parameter adjustment, and then output by the display 13.
