[0047] Through the above drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and the textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0048] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] A liquid crystal display unit is a non-self-luminous electronic device that does not have the property of emitting light itself and needs to rely on a backlight unit to provide light sources. The backlight unit provides the necessary light sources, and the liquid crystal display unit adjusts the transmittance of light using the optical properties of liquid crystal molecules to display images.

[0050] Exemplarily, the backlight unit may include an active matrix (AM) drive and a light-emitting unit, and the light-emitting unit may include one or more mini light-emitting diodes (Mini-LEDs). The backlight unit controls the brightness of each mini light-emitting diode through active matrix drive, enabling local dimming, dynamically adjusting the backlight brightness of different regions according to the image content, thereby improving the contrast and color performance.

[0051] In practical applications, the synchronization of the liquid crystal display unit and the backlight unit is very important in a display device. If the synchronization between the liquid crystal display unit and the backlight unit cannot be achieved, it may cause a decrease in brightness or the appearance of afterimages, affecting the picture effect.

[0052] For example, the lighting direction of the liquid crystal display unit is from top to bottom, that is, along the Figure 1 x direction in Figure 1 , and the lighting direction of the backlight unit also needs to be from top to bottom, that is, along the Figure 2 x direction in

[0053] In some embodiments, for each frame of the picture: while sending display data to the liquid crystal display unit, brightness data is sent to the backlight unit. For example, as shown in Figure 3 , in the (n - 1)-th frame of the picture, while sending the display data of the (n - 1)-th frame of the picture to the liquid crystal display unit, the brightness data of the (n - 1)-th frame of the picture is sent to the backlight unit. Again, in the n-th frame of the picture, while sending the display data of the n-th frame of the picture to the liquid crystal display unit, the brightness data of the n-th frame of the picture is sent to the backlight unit.

[0054] When the backlight unit receives the brightness data, it starts to emit light; when the liquid crystal display unit receives the display data, it controls the liquid crystal molecules in the liquid crystal display unit to start rotating. The liquid crystal molecules can correctly control the passage of light only when they rotate to a preset angle, thereby displaying an image. Therefore, the moment when the backlight unit emits light is earlier than the moment when the liquid crystal display unit displays an image.

[0055] However, it takes a certain amount of time for the liquid crystal molecules to rotate to the preset angle. As Figure 4 shown, T1 represents the moment when the backlight unit emits light; T2 represents the moment when the liquid crystal molecules rotate to the preset angle; S1 represents the time required for the liquid crystal molecules to rotate to the preset angle; S2 represents the time when the liquid crystal molecules are at the preset angle; S1 + S2 represents the time when the backlight unit emits light. During the time required for the liquid crystal molecules to rotate to the preset angle, the liquid crystal molecules cannot completely block or transmit light, resulting in partial light leakage and thus generating afterimages.

[0056] Therefore, if the lighting time of the backlight unit is too early, afterimages are likely to occur. If the lighting time of the backlight unit is too late, it may cause a decrease in brightness and affect the normal display of the image.

[0057] For this reason, the present application proposes a control method for a display device. When the liquid crystal groups in the liquid crystal display unit rotate to a first preset angle, brightness data is sent to the backlight unit. Then, when the liquid crystal molecules in the liquid crystal display unit rotate to a second preset angle, the backlight unit can emit light based on the brightness data. By controlling the backlight unit not to emit light before the liquid crystal molecules rotate to the first preset angle, the afterimages caused by light leakage during the rotation stage of the liquid crystal molecules can be reduced, and the normal display of the image can be ensured.

[0058] The technical solution of the present application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0059] Figure 5 The flowchart of a control method for a display device provided by an embodiment of the present application is shown. As Figure 5 shown, with the controller as the execution subject, the method of this embodiment may include the following steps:

[0060] S101. Send the display data of the target frame image to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit.

[0061] In the embodiment of the present application, when the liquid crystal display unit receives the display data of the target frame image, it controls the rotation of the liquid crystal molecules in the liquid crystal display unit. Specifically, the liquid crystal display unit includes a plurality of liquid crystal pixels, and each liquid crystal pixel is composed of a plurality of liquid crystal molecules. When the display data is applied to the liquid crystal pixels, the liquid crystal molecules in the liquid crystal pixels can be controlled to rotate.

[0062] Exemplarily, the display data includes a voltage signal. When the voltage signal is applied to the liquid crystal pixels, the liquid crystal molecules in the liquid crystal pixels can be controlled to rotate.

[0063] The rotation angle of the liquid crystal molecules in the liquid crystal display unit affects the light transmittance, and thus can affect the brightness, contrast, color performance, etc. of the liquid crystal display unit, and further affects the display effect of the screen.

[0064] Exemplarily, the display data may also include text and image information, so that a screen including text, images, etc. can be displayed on the liquid crystal display unit.

[0065] In some embodiments, the liquid crystal display unit is used to display multiple frames of pictures, and the target frame picture can be any frame of the multiple frames of pictures. When the target frame picture needs to be displayed, the display data of the target frame picture is sent to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit.

[0066] For example, if the target frame picture is the first frame picture of the multiple frames of pictures, the display data of the first frame picture can be sent to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit.

[0067] S102. When the liquid crystal molecules in the liquid crystal display unit rotate to a first preset angle, send brightness data to the backlight unit.

[0068] In the embodiments of the present application, when the liquid crystal molecules in the liquid crystal display unit rotate to a first preset angle, brightness data is sent to the backlight unit. Since it takes a certain amount of time for the backlight unit to emit light based on the brightness data after the brightness data is sent to the backlight unit, therefore, when the liquid crystal molecules in the liquid crystal display unit rotate to a first preset angle, sending the brightness data to the backlight unit can provide backlight in time and ensure the normal display of the screen.

[0069] In some embodiments, a first preset voltage is applied to the liquid crystal display unit to control the liquid crystal molecules in the liquid crystal display unit to rotate to a first preset angle. It should be noted that liquid crystal materials are anisotropic, and their molecules can rotate and rearrange under the action of an electric field. Therefore, by applying a certain voltage to the liquid crystal display unit, the liquid crystal molecules in the liquid crystal display unit can be controlled to rotate to a certain angle.

[0070] In some examples, the liquid crystal display unit is used to display multiple frames of pictures, and each frame of picture has corresponding first preset angle and brightness data. For each frame of picture, when the liquid crystal molecules rotate to the corresponding first preset angle, brightness data is sent to the backlight unit to be able to provide backlight in time.

[0071] Such as Figure 6As shown, for the (n - 1)-th frame, when the liquid crystal molecules rotate to the first preset angle corresponding to the (n - 1)-th frame, the brightness data corresponding to the (n - 1)-th frame is sent to the backlight unit; for the n-th frame, when the liquid crystal molecules rotate to the first preset angle corresponding to the n-th frame, the brightness data corresponding to the n-th frame is sent to the backlight unit.

[0072] Exemplarily, the brightness data corresponding to each frame can be different, so the backlight unit can have different light emission intensities under the control of the brightness data corresponding to each frame.

[0073] In some examples, the brightness data can be sent to the backlight unit based on the second vertical synchronization signal to ensure the accurate transmission of the brightness data of each frame.

[0074] S103. When the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angle, control the backlight unit to emit light based on the brightness data, so as to display the target frame on the liquid crystal display unit.

[0075] Among them, the first preset angle is less than the second preset angle.

[0076] In the embodiment of the present application, when the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angle, control the backlight unit to emit light based on the brightness data. Before the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angle, the backlight unit does not emit light, thereby avoiding the afterimage caused by partial light transmission during the process of the liquid crystal molecules rotating to the second preset angle. And because the backlight unit emits light when the liquid crystal molecules rotate to the first preset angle, the normal display of the target frame on the liquid crystal display unit can be ensured.

[0077] Moreover, when the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angle, the brightness data is sent to the backlight unit. Considering that it takes a certain amount of time for the backlight unit to receive the brightness data and emit light based on the brightness data, when the brightness data is sent to the backlight unit before the liquid crystal molecules rotate to the second preset angle, when the backlight unit receives the brightness data and emits light based on the brightness data, the liquid crystal molecules can rotate to the second preset angle or be close to the second preset angle, ensuring the normal display of the picture.

[0078] In some embodiments, the voltage applied to the liquid crystal display unit is increased from the first preset voltage to the second preset voltage to control the liquid crystal molecules in the liquid crystal display unit to rotate to the second preset angle. When the liquid crystal molecules rotate to the second preset angle, control the backlight unit to emit light based on the brightness data.

[0079] In some examples, a liquid crystal display unit is used to display multiple frames of images. Each frame of image has corresponding first preset angles, brightness data, second preset angles, and brightness data. For each frame of image, when the liquid crystal molecules rotate to the corresponding first preset angles, brightness data is sent to the backlight unit. When the backlight unit receives the brightness data and emits light based on the brightness data, the liquid crystal molecules can rotate to the second preset angles. At this time, the backlight provided by the backlight unit passes through the liquid crystal molecules rotated to the second preset angles, thereby ensuring the normal display of the image.

[0080] As Figure 7 shown, T1 represents the moment when the brightness data starts to be transmitted, that is, the moment when the liquid crystal molecules rotate to the first preset angles. T2 represents the moment when the liquid crystal molecules rotate to the second preset angles. S1 represents the time required for the liquid crystal molecules to rotate to the second preset angles. S2 represents the time when the backlight unit emits light, that is, the time when the liquid crystal molecules are at the preset angles. Therefore, when the liquid crystal molecules rotate to the second preset angles, the backlight unit emits light, avoiding the afterimage caused by partial light transmission before the liquid crystal molecules rotate to the first preset angles.

[0081] Exemplarily, the first preset angles corresponding to each frame of image can be different or the same. The first preset angles corresponding to each frame of image can be determined according to the second preset angles corresponding to each frame of image to ensure that the time for the liquid crystal molecules to rotate from the first preset angles to the second preset angles is close to or the same as the time from sending the brightness data to the backlight unit until the backlight unit emits light through the brightness data.

[0082] For example, when n = 2, when the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angles corresponding to the second frame of image, the brightness data of the second frame of image is sent to the backlight unit to control the backlight unit to emit light through the brightness data of the second frame of image when the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angles corresponding to the second frame of image.

[0083] For another example, when n = 3, when the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angles corresponding to the third frame of image, the brightness data of the third frame of image is sent to the backlight unit to control the backlight unit to emit light through the brightness data of the third frame of image when the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angles corresponding to the third frame of image.

[0084] Exemplarily, the brightness data corresponding to each frame of image can be different. Therefore, the backlight unit can have different light emission intensities under the control of the brightness data corresponding to each frame of image.

[0085] In some embodiments, when the liquid crystal molecules in the liquid crystal display unit are at a second preset angle corresponding to the (n - 1)-th frame image for a first preset time, the display data of the n-th frame image is sent to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit. Compared with rotating back from the second preset angle corresponding to the (n - 1)-th frame image to the initial state and then rotating from the initial state to the second preset angle corresponding to the n-th frame image, the liquid crystal molecules directly rotate from the second preset angle corresponding to the (n - 1)-th frame image to the second preset angle corresponding to the n-th frame image, which can shorten the time required for the liquid crystal molecules to rotate to the second preset angle corresponding to the n-th frame image, reduce the afterimage caused by light leakage, and improve the image effect. It should be noted that the first preset time is a period of time, and the specific duration is determined according to the actual situation. For example, it may be related to the refresh rate. The higher the refresh rate, the longer the first preset time can be; the lower the refresh rate, the shorter the first preset time can be.

[0086] For example, when n = 2, when the liquid crystal molecules in the liquid crystal display unit are at a second preset angle corresponding to the first frame image for a first preset time, the display data of the second frame image is sent to the liquid crystal display unit.

[0087] For another example, when n = 3, when the liquid crystal molecules in the liquid crystal display unit are at a second preset angle corresponding to the second frame image for a first preset time, the display data of the third frame image is sent to the liquid crystal display unit.

[0088] Exemplarily, the first preset time can be determined according to the actual situation and is not limited herein.

[0089] In some embodiments, based on the first vertical synchronization signal, the display data of the target frame image is sent to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit. The first vertical synchronization signal is used to indicate the moment of displaying a new frame image, that is, it indicates that the current frame has been completed and the next frame can be displayed. By sending the display data of the target frame image to the liquid crystal display unit through the first vertical synchronization signal, the correct display of the image is ensured.

[0090] Exemplarily, for each frame image, the interval between the first vertical synchronization signal and the second vertical synchronization signal is the same as or close to the time for the liquid crystal display unit to control the liquid crystal molecules to rotate to the corresponding first preset angle after receiving the display data.

[0091] The control method of the display device provided by the present application sends the display data of the target frame image to the liquid crystal display unit to control the rotation of the liquid crystal molecules in the liquid crystal display unit. When the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angle, the brightness data is sent to the backlight unit. Then, when the liquid crystal molecules in the liquid crystal display unit rotate to the second preset angle, the backlight unit can receive the brightness data, so that the backlight unit can be controlled to emit light based on the brightness data. By controlling the backlight unit not to emit light before the liquid crystal molecules rotate to the first preset angle, the afterimage caused by light leakage during the rotation stage of the liquid crystal molecules can be reduced, and the normal display of the image can be ensured.
