[0047] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope 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

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

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

[0050] For example, the backlight unit may include an active matrix (AM) driver and a light-emitting unit. The light-emitting unit may include one or more sub-millimeter light-emitting diodes (Mini Light Emitting Diode, Mini-LED). The backlight unit controls the brightness of each sub-millimeter light-emitting diode through the active matrix driver, and can achieve local dimming (Local Dimming), dynamically adjusting the backlight brightness of different areas according to the image content, thereby improving contrast and color performance.

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

[0052] For example, the lighting direction of the liquid crystal display unit is from top to bottom, that is, along Figure 1 In the x direction, the lighting direction of the backlight unit also needs to be from top to bottom, that is, along Figure 1 In the x direction. Figure 2 As shown, the time required for the liquid crystal display unit to light up from top to bottom is f1, and the lighting time of the backlight unit also needs to be f1.

[0053] In some embodiments, for each frame: while sending the display data to the liquid crystal display unit, the brightness data is sent to the backlight unit. Figure 3 As shown, in the n-1 frame, the display data of the n-1 frame is sent to the liquid crystal display unit, and the brightness data of the n-1 frame is sent to the backlight unit. For another example, in the n frame, the display data of the n frame is sent to the liquid crystal display unit, and the brightness data of the n frame 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. Only when the liquid crystal molecules rotate to a preset angle can they correctly control the passage of light to display the picture. Therefore, the time when the backlight unit emits light is earlier than the time when the liquid crystal display unit displays the picture.

[0055] However, it takes a certain amount of time for the liquid crystal molecules to rotate to the preset angle, such as Figure 4 As shown in the figure, T1 represents the time when the backlight unit emits light; T2 represents the time when the liquid crystal molecules rotate to a 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 fail to completely block or transmit light, resulting in partial light leakage, thus producing afterimages.

[0056] Therefore, if the backlight unit is turned on too early, afterimages are likely to occur, and if the backlight unit is turned on too late, the brightness may be reduced, affecting the normal display of the picture.

[0057] To this end, the present application proposes a control method for a display device, wherein when the liquid crystal group in the liquid crystal display unit rotates to a first preset angle, light brightness data is transmitted 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 afterimage caused by light leakage during the rotation stage of the liquid crystal molecules can be reduced, and the normal display of the picture can be guaranteed.

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

[0059] Figure 5 FIG. 1 is a flow chart showing a method for controlling a display device provided by an embodiment of the present application. Figure 5 As shown, with the controller as the execution subject, the method of this embodiment may include the following steps:

[0060] S101 . Sending display data of a target frame image to a liquid crystal display unit to control the rotation of 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 picture, the liquid crystal molecules in the liquid crystal display unit are controlled to rotate. Specifically, the liquid crystal display unit includes a plurality of liquid crystal pixels, each of which is composed of a plurality of liquid crystal molecules. When the display data is applied to the liquid crystal pixel, the liquid crystal molecules in the liquid crystal pixel can be controlled to rotate.

[0062] For example, the display data includes a voltage signal, and when the voltage signal is applied to a liquid crystal pixel, the liquid crystal molecules in the liquid crystal pixel can be controlled to rotate.

[0063] The rotation angle of the liquid crystal molecules in the liquid crystal display unit affects the transmittance of light, which in turn can affect the brightness, contrast, color performance, etc. of the liquid crystal display unit, thereby affecting the picture display effect.

[0064] For example, the display data may also include text and image information, so that a picture 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, and the target frame can be any frame in the multiple frames. When the target frame needs to be displayed, display data of the target frame is sent to the liquid crystal display unit to control the rotation of liquid crystal molecules in the liquid crystal display unit.

[0066] For example, if the target frame is the first frame of multiple frames, display data of the first frame may be sent to the liquid crystal display unit to control the rotation of 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, brightness data is sent to the backlight unit.

[0068] In an embodiment 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 from sending the brightness data to the backlight unit until the backlight unit emits light based on the brightness data, when the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angle, sending the brightness data to the backlight unit can provide backlight in a timely manner to ensure normal display of the picture.

[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 the liquid crystal material has anisotropy, and its 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, each frame having a corresponding first preset angle and brightness data. For each frame, when the liquid crystal molecules rotate to the corresponding first preset angle, the brightness data is sent to the backlight unit so that the backlight can be provided in time.

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

[0072] For example, the brightness data corresponding to each frame of the picture may be different, so the backlight unit may have different luminous intensities under the control of the brightness data corresponding to each frame of the picture.

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

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

[0075] The first preset angle is smaller 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, the backlight unit is controlled to emit light based on the brightness data, and 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 residual image caused by the 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, it can ensure that the liquid crystal display unit displays the target frame normally.

[0077] Furthermore, when the liquid crystal molecules in the liquid crystal display unit rotate to the first preset angle, brightness data is sent to the backlight unit. Considering that it takes a certain amount of time from sending the brightness data to the backlight unit until the backlight unit emits light according to the brightness data, 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 close to the second preset angle to ensure normal display of the picture.

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

[0079] In some examples, the liquid crystal display unit is used to display multiple frames, each frame having a corresponding first preset angle, brightness data and a second preset angle and brightness data. For each frame, when the liquid crystal molecules rotate to the corresponding first preset angle, the 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 angle. At this time, the backlight provided by the backlight unit transmits the liquid crystal molecules rotated to the second preset angle, thereby ensuring the normal display of the picture.

[0080] like Figure 7 As shown in the figure, 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 angle, T2 represents the moment when the liquid crystal molecules rotate to the second preset angle, S1 represents the time required for the liquid crystal molecules to rotate to the second preset angle, and S2 represents the time when the backlight unit emits light, that is, the time when the liquid crystal molecules are at the preset angle. Therefore, when the liquid crystal molecules rotate to the second preset angle, the backlight unit emits light to avoid the residual image caused by partial light transmission before the liquid crystal molecules rotate to the first preset angle.

[0081] For example, the first preset angle corresponding to each frame of the image can be different or the same, and the first preset angle corresponding to each frame of the image can be determined based on the second preset angle corresponding to each frame of the image to ensure that the time it takes for the liquid crystal molecules to rotate from the first preset angle to the second preset angle is close to or the same as the time it takes for brightness data to be sent to the backlight unit until the backlight unit emits light through the brightness data.

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

[0083] For another example, when n is 3, when the liquid crystal molecules in the liquid crystal display unit rotate to a first preset angle corresponding to a third frame, the brightness data of the third frame is sent to the backlight unit, so that when the liquid crystal molecules in the liquid crystal display unit rotate to a second preset angle corresponding to the third frame, the backlight unit is controlled to emit light through the brightness data of the third frame.

[0084] For example, the brightness data corresponding to each frame of the picture may be different, so the backlight unit may have different luminous intensities under the control of the brightness data corresponding to each frame of the picture.

[0085] In some embodiments, when the liquid crystal molecules in the liquid crystal display unit are at the second preset angle corresponding to the n-1 frame for the first preset time, the display data of the n-th frame 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 from the second preset angle corresponding to the n-1 frame to the initial state, and then rotating from the initial state to the second preset angle corresponding to the n-1 frame, the liquid crystal molecules directly rotate from the second preset angle corresponding to the n-1 frame to the second preset angle corresponding to the n-1 frame, which can shorten the time required for the liquid crystal molecules to rotate to the second preset angle corresponding to the n-1 frame, reduce the residual image caused by light leakage, and improve the picture 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 can be related to the refresh rate. The higher the refresh rate, the longer the first preset time can be, and the lower the refresh rate, the shorter the first preset time can be.

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

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

[0088] For example, the first preset time can be determined according to actual conditions and is not limited here.

[0089] In some embodiments, based on the first vertical synchronization signal, the display data of the target frame 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, that is, to indicate that the current frame has been completed and the next frame can be displayed. The display data of the target frame is sent to the liquid crystal display unit through the first vertical synchronization signal to ensure the correct display of the image.

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

[0091] The control method of the display device provided in the present application sends display data of the target frame image to a liquid crystal display unit to control the rotation of liquid crystal molecules in the liquid crystal display unit, and sends brightness data to a backlight unit when the liquid crystal molecules in the liquid crystal display unit rotate to a first preset angle. Then, when the liquid crystal molecules in the liquid crystal display unit rotate to a second preset angle, the backlight unit can receive the brightness data, thereby controlling the backlight unit 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 is reduced, and the normal display of the image can be ensured.
