Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure. Embodiments of the present disclosure are described in detail below with reference to the attached drawings.

The screen color adjustment method provided by the embodiment of the disclosure can be applied to a display control scene of a screen, and can be particularly applied to a display device provided with the screen. The display device may be, for example, a portable electronic device such as a notebook computer, a tablet computer, a palm computer, a vehicle-mounted electronic device, a wearable device, an ultra mobile personal computer (Ultra Mobile Personal Computer, UMPC), a netbook, a mobile terminal, or a personal digital assistant (Personal Digital Assistant, PDA), or a non-portable electronic device such as a network attached memory (Network Attached Storage, NAS), a personal computer (Personal Computer, PC), a Television (Television), a teller machine, or a self-service machine, and the embodiments of the disclosure are not limited in particular.

With the increasing demand for consumer electronics terminals, the market demand for screens will increase rapidly. In the related art, display control may be performed on a screen by means of pulse width modulation. For example, a control signal is set for the screen, and the on-off state of each display transistor in the screen is controlled by the high and low level of the control signal.

In the related art, in the process of performing display control of a screen with a control signal, it is generally necessary to adjust the level switching frequency of the control signal. For example, the control signal is set to perform level switching four times during display of each frame of the screen to cause the screen to perform screen display in the normal mode. For another example, the control signal is set to perform sixteen level switches during the display of each frame of the screen so that the screen performs the screen display in the eye-protection mode. In the related art, color adjustment is performed only by the same color adjustment parameter for different level switching frequencies of the control signal. Since the charging rate of each display transistor in a screen generally varies with the level switching frequency, the color performance of the same display transistor at different level switching frequencies is different. In other words, in the related art, the color adjustment method using the same color adjustment parameter for different level switching frequencies cannot meet the color adjustment requirement for the screen, which may cause the display color of the screen to deviate.

In view of this, the present disclosure proposes a screen color adjustment method that can perform color adjustment parameter quasi-matching for each level switching frequency of a control signal. On the basis, in the screen display process, the current color adjustment parameters matched with the current level switching frequency can be acquired, and the color value of the screen is adjusted according to the current color adjustment parameters. According to the method and the device, color adjustment aiming at different level switching frequencies can be achieved, and the problem that color deviation occurs on a screen due to the change of the level switching frequency of a control signal is solved.

Fig. 1 is a flowchart illustrating a screen color adjustment method according to an exemplary embodiment, as shown in fig. 1, including the following steps.

In step S11, the current level switching frequency of the control signal for performing display control on the screen is determined.

In the embodiment of the disclosure, the control signal may be a square wave signal, and the on-off state of each display transistor in the screen may be controlled by the high and low levels of the square wave signal.

In step S12, a current color adjustment parameter matching the current level switching frequency is acquired, and color value adjustment is performed on the screen with the current color adjustment parameter.

According to the screen color adjusting method provided by the embodiment of the disclosure, under the condition that the control signal is used for carrying out display control on the screen at any level switching frequency, the better color expression of the screen can be ensured, and the visual effect of the screen display picture can be improved.

For example, the color adjustment parameters may be determined for each level switching frequency in advance, so as to construct a one-to-one correspondence relationship between the plurality of level switching frequencies and the multi-set color adjustment parameters. Further, under the condition that the current level switching frequency of the control signal is determined, the current color adjustment parameter matched with the current level switching frequency can be determined according to the corresponding relation between the level switching frequency and the color adjustment parameter, so as to adjust the color value of the screen.

For example, the correspondence between the level switching frequency and the color adjustment parameter may be determined as follows.

Fig. 2 is a flowchart of a method for determining a correspondence between a level switching frequency and a color adjustment parameter according to an exemplary embodiment, as shown in fig. 2, including the following steps S21 to S23.

In step S21, a color value setting value of the screen at the target level switching frequency is determined, and a color value detection value of the screen at the target level switching frequency is determined.

The target level switching frequency may be any one of a plurality of different level switching frequencies. For example, the color value detection value of the screen at the target level switching frequency may be determined by means of optical verification. For example, the control screen is displayed with the color value set value at the target level switching frequency, and the screen is optically checked by the optical probe to obtain the color value detection value of the screen at the target level switching frequency.

In step S22, a target color adjustment parameter matching the target level switching frequency is determined based on the degree of difference between the color value setting value and the color value detection value.

For example, the target color adjustment parameter matching the target level switching frequency may be set according to a color value difference value between the color value setting value and the color value detection value. Based on this, the color value setting value is adjusted by the target color adjustment parameter, and the color value detection value can be made to coincide with the adjusted color value setting value.

In step S23, a correspondence relationship between the target level switching frequency and the target color adjustment parameter is created.

It is understood that the created correspondence is a one-to-one correspondence between the target level switching frequency and the target color adjustment parameter. In the embodiment of the disclosure, by repeatedly executing the steps S21 to S23 a plurality of times, a plurality of different correspondence relationships between a plurality of different level switching frequencies and a plurality of different color adjustment parameters corresponding to the different level switching frequencies can be obtained. In one embodiment, in the case of determining the correspondence between the level switching frequency and the color adjustment parameter, the current color adjustment parameter matching the current level switching frequency may be determined by the correspondence between the level switching frequency and the color adjustment parameter.

Fig. 3 is a flowchart illustrating another screen color adjustment method according to an exemplary embodiment, and as shown in fig. 3, step S31 in the embodiment of the present disclosure is similar to the execution method of step S11 in fig. 1, and will not be described herein.

In step S32, a current color adjustment parameter matching the current level switching frequency is determined based on the correspondence between the level switching frequency and the color adjustment parameter, and color value adjustment is performed on the screen with the current color adjustment parameter.

In general, in a normal production process of a screen, color correction is performed by setting gray scale adjustment parameters, so that each display area in the screen has the same color expression when the screen displays a white picture. In the embodiment of the disclosure, a color adjustment parameter for compensating the gray scale adjustment parameter can be additionally set on the basis of the gray scale adjustment parameter, and then the color value of the screen is adjusted by the compensated gray scale adjustment parameter.

Fig. 4 is a flowchart illustrating yet another screen color adjustment method according to an exemplary embodiment, and as shown in fig. 4, step S41 in the embodiment of the present disclosure is similar to the execution method of step S11 in fig. 1, and will not be described herein.

In step S42, a current color adjustment parameter matching the current level switching frequency is acquired.

In step S43, the gray-scale adjustment parameters of the screen are compensated with the current color adjustment parameters, and the color value of the screen is adjusted with the compensated gray-scale adjustment parameters.

According to the screen color adjusting method provided by the embodiment of the disclosure, the gray scale adjusting parameters can be compensated through the color adjusting parameters, and the color value of the screen is adjusted through the compensated gray scale adjusting parameters.

In the embodiment of the disclosure, the gray-scale adjustment parameters include, for example, a gray-scale gain parameter and a gray-scale compensation parameter, and there may be a plurality of color adjustment parameters for compensating the gray-scale adjustment parameters. For convenience of description, a plurality of different color compensation parameters for compensating the gray scale adjustment parameter are referred to as a first compensation parameter and a second compensation parameter, respectively.

In one embodiment, the color value adjustment may be performed on the screen as follows.

Fig. 5 is a flowchart illustrating another screen color adjustment method according to an exemplary embodiment, and as shown in fig. 5, step S51 and step S52 in the embodiment of the present disclosure are similar to the execution method of step S41 and step S42 in fig. 4, and are not described herein.

In step S53, the first compensation parameter is used to compensate the gray scale gain parameter, so as to obtain a compensated gray scale gain parameter, and the first compensation parameter and the second compensation parameter are used to compensate the gray scale compensation parameter, so as to obtain a compensated gray scale compensation parameter.

For example, the compensated gray-scale Gain parameter may be obtained by gain=gain×pset. The Gain' is a gray-scale Gain parameter after compensation, the Gain is a gray-scale Gain parameter, and the Pset is a first compensation parameter.

In step S54, the color value of the screen is adjusted based on the compensated gray-scale gain parameter and the compensated gray-scale compensation parameter.

For example, the compensated gray-scale compensation parameter may be obtained by offset = offset + psut. Wherein, offset' is the gray-scale compensation parameter after compensation, offset is the gray-scale compensation parameter, pset is the first compensation parameter, psup is the second compensation parameter.

On this basis, if the compensated gray-scale Gain parameter is Gain ', and the compensated gray-scale compensation parameter is offset', the color value of the screen can be adjusted by y=gain '×x+offset' (i.e., y= (gain×offset) ×pset+psup as shown in fig. 6). Wherein X is the color value before the color value adjustment is performed on the screen, and Y is the color value after the color value adjustment is performed on the screen. Taking an example of an R channel of any pixel unit (a pixel unit consisting of an R channel, a G channel, and a B channel of a three-primary color space), if the initial color value of the R channel of the pixel is Rx, the adjusted R channel color value (denoted by Ry in the example) can be obtained by ry= (gain×rx+offset) ×pset+psup. In addition, since the color expressions corresponding to the plurality of different display transistors in the screen are generally different, it is necessary to separately configure the grayscale gain parameter and the color adjustment parameter for each display transistor of any screen.

Fig. 7 is a schematic diagram illustrating one type of color adjustment parameter for determining different level switching frequencies according to an exemplary embodiment. Fig. 8 is a schematic diagram illustrating a screen color adjustment by color adjustment parameters, according to an example embodiment. For example, as shown in fig. 7, for a display device configured with a control signal, the level switching frequency P1 and the level switching frequency P2 may be configured in advance for the control signal, and the respective corresponding color adjustment parameters may be configured for the level switching frequency P1 and the level switching frequency P2, respectively. For example, pset1 and Psup1 are configured for the level switching frequency P1, and Pset2 and Psup2 are configured for the level switching frequency P2. Wherein Pset1 is a first compensation parameter corresponding to the level switching frequency P1, psup1 is a second compensation parameter corresponding to the level switching frequency P1, pset2 is a first compensation parameter corresponding to the level switching frequency P2, and Psup2 is a second compensation parameter corresponding to the level switching frequency P2.

For example, when the control signal performs display control on the screen at the level switching frequency P1, the gray-scale adjustment parameter is used to adjust the color value set value of the screen, and the optical probe is used to perform optical verification on the screen to determine the current color value detection value of the screen. Further, pset1 and Psup1 configured for the level switching frequency P1 may be determined from a color value difference value between the color value setting value and the color value detection value. For example, if the color value detection value X1 is recorded when the color value setting value is Y1, the color value setting value may be adjusted until the color value detection value is Y1. In this case, the adjusted color value set value Y2 is recorded, and Y1 is taken as the parameter X in y= (Gain x+offset) pset1+psup1, and Y2 is taken as the parameter Y in y= (Gain x+offset) pset1+psup1, resulting in a set of correspondence between psut 1 and Psup1. Further, by repeating the above-described process with another color value set value Y3 different from Y1, another set of correspondence between Pset1 and Psup1 is obtained. Based on this, the parameter values of the first compensation parameter Pset1 and the second compensation parameter Psup1 can be obtained through the two sets of correspondence relationships. In addition, for the level switching frequency P2, the manner of determining the first compensation parameter Pset2 and the second compensation parameter Psup2 is similar to the above embodiment, and will not be described herein.

Further, as shown in fig. 8, the level switching frequency of the control signal may be adjusted by an adjustment instruction of the level switching frequency. For example, if the display device currently performs display control on the screen by the control signal with the level switching frequency P1, the display device may be adjusted to perform display control on the screen by the control signal with the level switching frequency P2 by the adjustment instruction of the level switching frequency. In this process, the screen is color-adjusted with respect to the case where the level switching frequency is P2, with the color adjustment parameters Pset1 and Psup1 used by the display device, and with respect to the case where the level switching frequency is switched from P1 to P2, the screen is color-adjusted with respect to the color adjustment parameters Pset2 and Psup2 used by the display device. On the basis, the display device performs display control on the screen at the level switching frequency P1 or the level switching frequency P2, and the display picture of the screen has better color effect.

Based on the same conception, the embodiment of the disclosure also provides a screen color adjusting device.
