In the case that the power consumption of the display panel is not required to be small but a higher display quality is demanded, e.g., in the case that the display panel is in a normal operating mode, the to-be-displayed image on the display panel may be subjected to the color enhancement, so as to ensure the display quality.
In a possible embodiment of the present disclosure, as shown in
In this way, a part of the to-be-displayed image at a region of the display panel in a brilliant color may be subjected to the color enhancement, and a part of the to-be-displayed image at a region of the display panel in a dim color may not be subjected to the color enhancement. As a result, it is able to significantly reduce the power consumption of the display device without adversely affecting the user experience.
In a possible embodiment of the present disclosure, as shown in
In this way, a part of the to-be-displayed image at a region of the display panel where a high-resolution image is to be displayed may be subjected to the color enhancement, and a part of the to-be-displayed image at a region of the display panel where a low-resolution image is to be displayed may not be subjected to the color enhancement. As a result, it is able to significantly reduce the power consumption of the display device without adversely affecting the user experience.
The present disclosure further provides in some embodiments a control circuit of a display panel which, as shown in
According to the control circuit in the embodiments of the present disclosure, whether or not to subject the to-be-displayed image to the color enhancement is determined in accordance with the current display mode of the display panel and the image parameter of the to-be-displayed image. For example, a part of the to-be-displayed image at a region in a moderate color may not be subjected to the color enhancement, and a part of the to-be-displayed image at a region in a brilliant color may be subjected to the color enhancement. For another example, a part of the to-be-displayed image with a low resolution may not be subjected to the color enhancement, and a part of the to-be-displayed image with a high resolution may be subjected to the color enhancement. As a result, it is able to significantly reduce the power consumption of the display device without adversely affecting the user experience.

As a result, it is able to significantly reduce the power consumption of the display device without adversely affecting the user experience.
The present disclosure further provides in some embodiments a display device including a display panel and the above-mentioned control circuit of the display panel. The display device may be any product or member having a display function, e.g., a television, a display, a digital photo frame, a mobile phone or a flat-panel computer. The display device may further include a flexible circuit board, a printed circuit board and a back plate.
In a possible embodiment of the present disclosure, a base substrate of the display panel may be a silicon substrate, and the control circuit of the display panel may be integrated into the silicon substrate.

For example, an identified, executable code module or unit may include one or more physical or logical blocks including computer instructions, and for example, the module may be constructed as an object, a process or a function. Even so, the executable codes of the identified modules are unnecessary to be physically located together, but may include different instructions stored in different physical locations. In the case that these instructions are logically combined together, they form the modules or units and achieve the prescribed purposes of the modules or units.
Actually, the executable code module or unit may be a single instruction or a plurality of instructions, and may even be distributed at different code segments, in different programs, or across a plurality of memory devices. Also, operational data may be identified in the modules or units, implemented in any appropriate form, and organized in any data structure of an appropriate type. The operational data may be collected as a single data set, or distributed at different locations (including different memory devices), and may be at least partially present in a system or network merely as an electronic signal.
In addition, the modules or units (including but not limited to the display mode determination module 51, the processing module 52, the first processing unit 61, the division unit 71, the calculation unit 72, the second processing unit 73, the division unit 81, the resolution acquisition unit 82 and the third processing unit 83) may be implemented by a corresponding hardware circuit. The hardware circuit includes a very-large-scale integration (VLSI) circuit, a gate array, a semiconductor such as a logic chip or a transistor, or another discrete component in the related art. The modules or units may further be implemented by a programmable hardware device, such as a field-programmable gate array, a programmable array logic device and a programmable logic device.
In the method embodiments of the present disclosure, the order of the steps is not limited to the serial numbers thereof. For a person skilled in the art, any change in the order of the steps shall also fall within the scope of the present disclosure if without any creative effort.
The above are merely the preferred embodiments of the present disclosure, but the present disclosure is not limited thereto. Obviously, a person skilled in the art may make further modifications and improvements without departing from the spirit of the present disclosure, and these modifications and improvements shall also fall within the scope of the present disclosure.
