Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure is described in further detail below with reference to the embodiments and the accompanying drawings. The exemplary embodiments and descriptions of the present disclosure are provided herein for illustration of the present disclosure, but not for limitation of the present disclosure.
Before describing the embodiments of the present disclosure, some concepts related to the present disclosure are first explained as follows:
1. working principle of the display device:
the display device is provided with a pixel array, the pixel array comprises a plurality of pixels, and each pixel is composed of a plurality of sub-pixels with different colors. Each sub-pixel is connected with a Gate control line (Gate line) and a data line (Source line), each row of sub-pixels shares one Gate control line, and each column of sub-pixels shares one data line.
When a picture is displayed, progressive scanning can be realized through time division multiplexing of the gating control lines, so that the gating control lines of each row are sequentially opened, and the content displayed by each sub-pixel on each row is controlled through the data lines, thereby forming a frame of picture.
The voltage on the data line is controlled by the driving chip and corresponds to the content to be displayed by the sub-pixel, for example, the voltage is 0V when 0 gray scale is to be displayed and 5V when 255 gray scale is to be displayed. When the picture is updated, only the voltage on the data line needs to be controlled to change. Voltage variations can cause a load that is excessive when the voltage variations are excessive or too frequent. The data lines control the liquid crystal in the display device to turn, and if the load is too large, the voltage may be insufficient, which may affect the normal display effect.
2. Frame rate: updating times of the picture in unit time; when the frame rate is higher, the updating speed of the picture is higher, and when the frame rate is lower, the updating speed of the picture is lower.
Embodiments of the present disclosure provide an electronic device and a screen display method, and the present disclosure will be described in detail below.
Firstly, in practical application, when the display device needs to display a heavy-load picture, the voltage input to the display device by the driving chip changes greatly or changes too frequently, so that an excessive load is caused, and the picture display effect is affected. In the process, the input voltage of the driving chip also needs to be changed correspondingly, and whether the display device displays the heavy-load picture or not can be determined by detecting the change condition of the driving chip. Therefore, in the electronic device provided in this embodiment, the comparator is arranged to compare the input voltage of the driving chip with the preset reference voltage, and the comparison result can indicate the change condition of the input voltage of the driving chip.
Secondly, when the input voltage of the driving chip changes to a large extent or changes too frequently, in order to ensure the picture display effect, the frame rate can be reduced, and the change frequency of the picture data can be reduced, so that the picture display effect is improved. When the change amplitude of the input voltage of the driving chip is reduced or the change speed is reduced, the previous frame rate can be restored. For this reason, the electronic device provided in this embodiment adjusts the frame rate by the setting processor.
Fig. 1 is a schematic structural diagram illustrating an electronic device according to an exemplary embodiment, where the electronic device includes, as shown in fig. 1: a comparator 101, a processor 102, a driving chip 103, and a display device 104. The processor 102 is configured to control the driving chip 103, and the driving chip 103 is configured to control the display device 104 to display a picture.
The comparator 101 includes a first input terminal 1011, a second input terminal 1012 and an output terminal 1013, the processor 102 includes an input terminal 1021, the driving chip 103 includes an input terminal 1031 and an output terminal 1032, the display device 104 includes an input terminal 1041, and the output terminal 1032 of the driving chip 103 is connected to the input terminal 1041 of the display device 104, so as to control the display device 104 to display a picture.
In this embodiment, the first input terminal 1011 of the comparator 101 is connected to the input terminal 1031 of the driver chip 103, so that the voltage of the first input terminal 1011 is equal to the input voltage of the input terminal 1031; the voltage of the second input terminal 1012 of the comparator 101 is a preset reference voltage, which may be an input voltage of the driving chip 103 when the picture is normally displayed. For example, the second input terminal 1012 may be connected to a power supply that provides a predetermined reference voltage, thereby ensuring that the voltage at the second input terminal 1012 remains at the predetermined reference voltage.
The two inputs of the comparator 101 are analog signals, and the output is a binary signal. The comparator 101 takes a preset reference voltage as a reference voltage, compares the voltage of the first input terminal 1011 with the reference voltage, and outputs an electrical signal corresponding to the comparison result. Wherein, the comparison result comprises the following two types: the input voltage at the first input terminal 1011 is greater than the predetermined reference voltage, and the input voltage at the first input terminal 1011 is not greater than the predetermined reference voltage.
Since the voltage of the first input terminal 1011 is equal to the input voltage of the input terminal 1031, the input voltage of the input terminal 1031 can be compared with the preset reference voltage by the comparator 1011.
The output end 1013 of the comparator 101 is connected to the input end 1021 of the processor 102, and after the comparator 101 compares the input voltage of the first input end 1011 with the preset reference voltage and obtains the comparison result, the comparator will send an electrical signal corresponding to the comparison result to the processor 102 through the output end 1013, so that when the processor 102 receives the electrical signal, the magnitude relationship between the input voltage of the first input end and the preset reference voltage can be determined according to the electrical signal.
The electrical signal sent by the comparator 101 to the processor 102 may indicate the variation of the input voltage of the driving chip 103, so as to indicate whether the display device 104 is currently displaying a reloading picture. Therefore, the processor 102 may determine a frame rate corresponding to the electrical signal, send the frame rate to the driving chip 103, and control the display device 104 to display a picture at the frame rate by the driving chip 103.
In the electronic device provided by this embodiment, the comparator compares the input voltage of the first input terminal with the preset reference voltage, and the comparison result represents the change condition of the input voltage of the first input terminal, so as to represent the load size of the electronic device, and the frame rate corresponding to the comparison result is determined, and the frame rate is adjusted to adjust the picture display effect, so that the influence of the load size of the electronic device on the picture display effect is avoided.
In an exemplary embodiment, when the input voltage at the first input terminal 1011 is greater than the predetermined reference voltage, the comparator 101 sends a first electrical signal to the processor 102, where the first electrical signal indicates that the input voltage of the driving chip 103 is too large, and the electronic device may be displaying a heavy-load picture.
When receiving the first electrical signal, the processor 102 reduces the current frame rate to the first frame rate, and sends the first frame rate to the driving chip 103, and when receiving the first frame rate, the driving chip 103 controls the display device 104 to display the image at the first frame rate.
Or, the comparator 101 sends the first electrical signal to the processor 102 multiple times, when the processor 102 determines that the number of times of receiving the first electrical signal reaches a preset number of times, the current frame rate is reduced to the first frame rate, and the first frame rate is sent to the driving chip 103, and when the driving chip 103 receives the first frame rate, the display device 104 is controlled to display the picture at the first frame rate.
The first frame rate may be a preset minimum frame rate of the display device 104, and the processor 102 directly reduces the current frame rate to the preset minimum frame rate.
Alternatively, the first frame rate is a frame rate smaller than the current frame rate by a preset difference, and the preset difference may be determined according to a frame rate difference required in general picture adjustment. The processor 102 reduces the current frame rate by a preset difference value to obtain the first frame rate. In practical applications, when the frame rate obtained by reducing the current frame rate by the preset difference value by the processor 102 is smaller than the preset minimum frame rate, the current frame rate may be reduced to the preset minimum frame rate.
In the embodiment, the display load condition is detected by detecting the change condition of the input voltage of the driving chip, so that the frame rate is properly reduced, and the problem of abnormal display caused by overhigh load is solved.
In another exemplary embodiment, when the input voltage at the second input terminal 1011 is not greater than the preset reference voltage, the comparator 101 sends a second electrical signal to the processor 102, the second electrical signal indicates that the input voltage of the driving chip 103 is not large, and the electronic device may have stopped displaying the heavy-load picture.
When receiving the second electrical signal, the processor 102 increases the current frame rate to a second frame rate, and sends the second frame rate to the driving chip 103, and when receiving the second frame rate, the driving chip 103 controls the display device 104 to display the image at the second frame rate.
Or, the comparator 101 sends the second electrical signal to the processor 102 multiple times, when the processor 102 determines that the number of times of receiving the second electrical signal reaches the preset number of times, the current frame rate is increased to the second frame rate, and the second frame rate is sent to the driving chip 103, and when the driving chip 103 receives the second frame rate, the display device 104 is controlled to display the image at the second frame rate.
If the second frame rate is the preset maximum frame rate of the display device, the processor 102 directly increases the current frame rate to the preset maximum frame rate.
Or, the second frame rate is a frame rate greater than the current frame rate by a preset difference, and the preset difference may be determined according to a frame rate difference required in general picture adjustment. The processor 102 increases the current frame rate by a preset difference value to obtain the second frame rate. In practical applications, when the frame rate obtained by increasing the current frame rate by the preset difference value by the processor 102 is greater than the preset maximum frame rate, the current frame rate may be increased to the preset maximum frame rate.
According to the display control method and the display control device, the load condition of display is detected by detecting the change condition of the input voltage of the driving chip, so that the frame rate is increased and the frame rate is properly reduced when the load is recovered to be normal, and the problem of abnormal display caused by overhigh load is solved.
In another embodiment, the electronic device may include a power chip 105, and the power chip 105 is connected to the first input terminal 1011 for providing an input voltage to the first input terminal 1011 and the input terminal 1031 of the driving chip 103. For example, the power chip 105 may be VSP/VSN (analog power, ± 5.5V), VDDI (digital power, 1.8V).
The power chip 105 may be the processor 102 itself, or may be a device capable of providing power for the driver chip 103 besides the processor 102, which is not limited in this embodiment.

in step 201, the input voltage of the driver chip is compared with a preset reference voltage to obtain a comparison result.
In step 202, the corresponding frame rate is determined according to the comparison result, and the screen is displayed according to the frame rate.
In the method provided by this embodiment, the input voltage of the first input terminal is compared with the preset reference voltage, and the comparison result represents the change condition of the input voltage of the first input terminal, so that the corresponding frame rate is determined according to the comparison result, and the frame rate is adjusted to adjust the image display effect, thereby avoiding the influence of the load size of the electronic device on the image display effect.
In another embodiment, determining the corresponding frame rate according to the comparison result includes:
and when the input voltage is greater than the preset reference voltage, reducing the current frame rate to a first frame rate.
In another embodiment, determining the corresponding frame rate according to the comparison result includes:
and when the times that the input voltage is greater than the preset reference voltage reach the preset times, reducing the current frame rate to a first frame rate.
