[0034] The display device in this embodiment includes a display panel, which includes a dimming box 510 and a display box. The dimming box 510 is provided with a first polarizer and a semi-transparent and semi-reflective film on the upper and lower sides, respectively, and the first polarizer is parallel to the transmission axis of the semi-transparent and semi-reflective film.

Preferably, the projections of the first and second viewing angle electrodes on the second substrate are parallel to each other and alternately distributed, and the projections of the third and fourth viewing angle electrodes on the second substrate are parallel to each other and alternately distributed. Preferably, the first and third viewing angle electrodes are both in the first layer, and the second and fourth viewing angle electrodes are both in the second layer.
[0035] Figure 2 FIG. 1 is a flow chart of a method for displaying a logo on a display device according to an embodiment of the present invention. Figure 2 As shown, this embodiment provides a method for displaying a logo on a display device, including:
[0036] S110, obtaining a first control signal for entering a sleep state, a hibernation state, or a shutdown state to display an identification mode;
[0037] S120, according to the first control signal, outputs an enable signal and identification control data to generate a reflection voltage signal to the identification area electrode, and also generates a non-reflection voltage signal to the non-identification area electrode, so that the ambient light reflected by the semi-transparent and semi-reflective film passes through the identification area corresponding to the identification area electrode, so that the display panel displays the identification content of the identification area.
[0038] Specifically, please combine Figure 1 and Figure 2 When the processing module 100 obtains a first control signal for entering a sleep state, hibernation state, or shutdown state, for example, when the first control signal is BL_EN, which is at a low level (L), the processing module 100 outputs an enable signal, such as I_EN, at a high level (H) to the transformer module 200 based on the first control signal, and also outputs the identification control data to the digital-to-analog converter module 300 via SPI or other transmission methods. The transformer module 200 provides two DC power supply voltages, such as +5.2V and -5.2V, to the digital-to-analog converter module 300 based on the enable signal. The digital-to-analog conversion module 300 outputs a reflected voltage signal to the marking area electrode in the marking area after amplification and biasing by the first voltage amplification unit 410 based on the marking control data and two DC power supply voltages. The reflected voltage signal may include a first drive signal and a second drive signal. The marking area electrode may include a first viewing angle electrode and a second viewing angle electrode. That is, after amplification and biasing by the first voltage amplification unit 410, the first drive signal and the second drive signal may be output to the first viewing angle electrode and the second viewing angle electrode in the marking area, respectively. The digital-to-analog conversion module 300 also outputs a non-reflective voltage signal to the non-marking area electrode in the non-marking area after amplification and biasing by the second voltage amplification unit 420. The non-reflective voltage signal may include a third drive signal and a fourth drive signal. The non-marking area electrode may include a third viewing angle electrode and a fourth viewing angle electrode. That is, after amplification and biasing by the second voltage amplification unit 420, the third drive signal and the fourth drive signal may be output to the third viewing angle electrode and the fourth viewing angle electrode in the non-marking area, respectively. This embodiment does not limit the liquid crystal molecules in the first liquid crystal layer to be positive liquid crystal molecules or negative liquid crystal molecules. The following only uses the liquid crystal molecules in the first liquid crystal layer as an example for description. In logo display mode, the first and second drive signals provided to the logo area can be rectangular square wave AC signals, while the third and fourth drive signals provided to the non-logo area can correspond to rectangular square wave AC signals with different or unequal voltages. This allows ambient light reflected by the transflective film to pass through the logo area, and the display panel then displays the logo content of the logo area. The logo content can include, but is not limited to, a brand logo and slogan. Thus, the display device can enter logo display mode to display the logo content when in sleep, hibernation, or shutdown mode, thereby enhancing brand promotion.
[0039] In one embodiment of the invention, the logo display mode (Logo & slogan mode) includes one or more of the following display modes:
[0040] The first display mode (Customer mode) further includes the steps of: starting to count a first preset time; if the first preset time is reached, stopping outputting the enable signal and the identification control data, so that the display panel turns off the screen;
[0041] The second display mode (Showing mode 1) further includes the steps of: starting to count a second preset time; if the second preset time is reached, stopping outputting the enable signal and the identification control data so that the display panel turns off the screen; determining whether the first wake-up operation occurs, and if so, re-outputting the enable signal and the identification control data and re-starting to count the second preset time; determining whether the second wake-up operation occurs, and if so, entering the normal display mode;
[0042] The third display mode (Showing mode 2); The third display mode further includes the steps of: always outputting the enable signal and the identification control data so that the display panel always displays the identification content.
[0043] The following will be passed Figure 3 、 Figure 4 and Figure 5 and combined with Figure 1 , describing the specific implementation of each display mode in the identification display mode.
[0044] Figure 3 This is a flow chart of the first display mode of a display device according to an embodiment of the present invention. Figure 1 and Figure 3The operating process of the display device in the first display mode of this embodiment is as follows: when the processing module 100 obtains a first control signal for entering the identification display mode in the sleep state, hibernation state, or shutdown state, for example, when the first control signal is a BL_EN signal at a low level L, the display device can enter the identification display mode from the normal display mode. The processing module 100 executes the program configuration for the first display mode and can output an enable signal, such as an I_EN signal at a high level H, to the transformer module 200. It also outputs identification control data to the digital-to-analog conversion module 300 via SPI or other transmission methods. Based on the enable signal, the transformer module 200 provides two DC power supply voltages, such as +5.2V and -5.2V, to the digital-to-analog conversion module 300. Based on the identification control data and the two DC power supply voltages, the digital-to-analog conversion module 300 can output a first drive signal and a second drive signal, respectively, to the first viewing angle electrode and the second viewing angle electrode in the identification area after amplification and biasing by the first voltage amplification unit 410. It can also output a third drive signal and a fourth drive signal, respectively, to the third viewing angle electrode and the fourth viewing angle electrode in the non-identification area after amplification and biasing by the second voltage amplification unit 420. Thus, the ambient light reflected by the semi-transparent and semi-reflective film can pass through the logo area, allowing the display panel to display the logo content of the logo area, which can better promote the brand. At the same time, the processing module 100 starts timing for a first preset time, such as 10 minutes; if the first preset time is reached, the output of the enable signal, such as the I_EN signal is low level L, is stopped, and the output of the logo control data, such as configuring the GPIO interface module to output a low level, is also stopped. Then the transformer module 200 does not output, that is, it does not provide two DC power supply voltages such as +5.2V and -5.2V, and the digital-to-analog conversion module 300 does not output. As a result, the first voltage amplification unit 410 and the second voltage amplification unit 420 have no output, and neither the logo area nor the non-logo area obtains voltage. The ambient light reflected by the semi-transparent and semi-reflective film cannot pass through the logo area, causing the display panel to stop displaying the logo content and enter the off screen.
[0045] Preferably, the first display mode of the identification display mode of this embodiment can be used for the user's sleep and shutdown operations. In the sleep state or shutdown state, the identification content is displayed within the first preset time, and then the screen is automatically turned off.
[0046] Figure 4 FIG is a flow chart of the second display mode of a display device according to an embodiment of the present invention. Figure 1 and Figure 4The operating process of the display device in the second display mode of this embodiment is as follows: when the processing module 100 obtains the first control signal for entering the identification display mode of the sleep state, hibernation state, or shutdown state, for example, when the first control signal is the BL_EN signal at a low level L, the display device can enter the identification display mode from the normal display mode. According to the program configuration of the second display mode, the processing module 100 outputs an enable signal, such as the I_EN signal at a high level H, to the transformer module 200 based on the first control signal, and also outputs identification control data to the digital-to-analog conversion module 300 via SPI or other transmission methods. The transformer module 200 provides two DC power supply voltages, such as +5.2V and -5.2V, to the digital-to-analog conversion module 300 based on the enable signal. Based on the logo control data and two DC power supply voltages, the digital-to-analog conversion module 300 outputs a first drive signal and a second drive signal, respectively, to the first and second viewing angle electrodes in the logo area after amplification and biasing by the first voltage amplification unit 410. Furthermore, after amplification and biasing by the second voltage amplification unit 420, the digital-to-analog conversion module 300 outputs a third drive signal and a fourth drive signal, respectively, to the third and fourth viewing angle electrodes in the non-logo area. This allows ambient light reflected by the transflective film to pass through the logo area, allowing the display panel to display the logo content in the logo area, effectively promoting the brand. At the same time, the processing module 100 starts timing the second preset time, such as 10 minutes; if the second preset time is reached, the output of the enable signal, such as the I_EN signal is low level L, and the output of the identification control data, such as configuring the GPIO interface module to output a low level, the transformer module 200 does not output, that is, it does not provide two DC power supply voltages such as +5.2V and -5.2V, and the digital-to-analog conversion module 300 does not output. As a result, the first voltage amplification unit 410 and the second voltage amplification unit 420 have no output, and neither the identification area nor the non-identification area obtains voltage. The ambient light reflected by the semi-transparent and semi-reflective film cannot pass through the identification area, causing the display panel to stop displaying the identification content and enter the off-screen state. In the identification display time period within the second preset time or the off-screen time period after the second preset time, it can be determined whether the first wake-up operation occurs. If so, the processing module 100 re-outputs the enable signal and identification control data, and restarts the timing of the second preset time; it can also be determined whether the second wake-up operation occurs. If so, the display device enters the normal display mode ( Figure 4 not shown).
[0047] In one embodiment of the invention, the first wake-up operation is pressing a preset key, such as the F2 key, and the second wake-up operation is pressing a key other than the preset key. However, the embodiment is not limited to this, and the first and second wake-up operations can also be operations such as moving the mouse, clicking the mouse, or touching the touch screen.
[0048] Preferably, the second display mode of the identification display mode of this embodiment can be used for the user's sleep operation. In the sleep state, the identification content is displayed within the second preset time, and then the screen is automatically turned off. The display device can re-enter the second display mode to display the identification content according to the first wake-up operation, or enter the normal display mode according to the second wake-up operation.
[0049] Figure 5 FIG. 1 is a flow chart of the third display mode of a display device according to an embodiment of the present invention. Figure 1 and Figure 5 The operating process of the display device in the third display mode of this embodiment is as follows: when the processing module 100 obtains a first control signal for entering the identification display mode in the sleep state, hibernation state, or shutdown state, for example, when the first control signal is a BL_EN signal at a low level L, the display device can enter the identification display mode from the normal display mode. According to the program configuration of the first display mode, the processing module 100 outputs an enable signal, such as a high level H, to the transformer module 200 based on the first control signal, and also outputs identification control data to the digital-to-analog conversion module 300 via SPI or other transmission methods. The transformer module 200 provides two DC power supply voltages, such as +5.2V and -5.2V, to the digital-to-analog conversion module 300 based on the enable signal. Based on the identification control data and the two DC power supply voltages, the digital-to-analog conversion module 300 outputs a first drive signal and a second drive signal, respectively, to the first viewing angle electrode and the second viewing angle electrode in the identification area after amplification and biasing by the first voltage amplification unit 410. The digital-to-analog conversion module 300 also outputs a third drive signal and a fourth drive signal, respectively, to the third viewing angle electrode and the fourth viewing angle electrode in the non-identification area after amplification and biasing by the second voltage amplification unit 420. Thus, ambient light reflected by the translucent film can pass through the logo area, allowing the display panel to display the logo content in the logo area, thereby better promoting the brand. In the third display mode, the processing module 100 continuously outputs the enable signal and logo control data, thereby allowing ambient light reflected by the translucent film to continuously pass through the logo area, allowing the display panel to continuously display the logo content.
[0050] Preferably, the third display mode of the logo display mode of this embodiment can be used for the user's sleep operation, so that the logo content is always displayed in the sleep state. This third display mode can be used in places such as display counters, so that the logo content can be displayed on the display panel while displaying the display device, thereby better promoting the brand.
[0051] In one embodiment of the invention, Figure 6 As shown, Figure 6This is a schematic diagram of the selection interface of each display mode in the identification display mode displayed in the normal display mode of an embodiment of the present invention. The identification display method of the display device of this embodiment includes: in the normal display mode, according to the user's operation, the display panel displays the selection interface of one or more display modes in the identification display mode; according to the selection of the display mode in the identification display mode, the identification display mode is configured.
[0052] In one embodiment of the invention, the steps of configuring the identification display mode according to the selection of the display mode in the identification display mode include: generating corresponding coding data according to the selection of the corresponding display mode; obtaining a display mode control signal generated according to the coding data, and configuring the identification display mode according to the display mode control signal.
[0053] Specifically, you can, but are not limited to, right-click on the desktop and select Figure 6 The display mode in the logo display mode (Logo & slogan mode) is shown in the selection interface for three display modes (the first display mode, Customer mode; the second display mode, Showing mode 1; and the third display mode, Showing mode 2). Click to select the corresponding display mode to set a vacant register module DPCD to obtain corresponding coded data. The timing controller TCON reads the coded data from this register module DPCD and generates a display mode control signal based on the coded data. The display mode control signal is sent to the processing module 100 via the GPIO port of the interface module. The processing module 100 then sets the display mode for the logo display mode accordingly. Preferably, the display mode initially set by the processing module 100 can be the first display mode.
[0054] The following table shows the relationship between the register module DPCD settings corresponding to the three display modes of one embodiment and the display mode control signal sent by the timing controller TCON to the processing module 100 via the interface module GPIO port. It can be seen that in the first display mode, the encoding data of the register module is 001, and the display mode control signal sent by the timing controller TCON via the interface module GPIO port is a high-level signal; in the second display mode, the encoding data of the register module is 010, and the display mode control signal sent by the timing controller TCON via the interface module GPIO port is a low-level signal; in the third display mode, the encoding data of the register module is 100, and the display mode control signal sent by the timing controller TCON via the interface module GPIO port is a square wave AC signal.
[0055]
[0056] In one embodiment of the invention, the step of configuring the logo display mode includes: entering the logo display mode according to a display mode selection in the logo display mode. In the normal display mode, a display panel displays a display mode selection interface in the logo display mode. After clicking to select a corresponding display mode, the display device enters the corresponding display mode in the logo display mode.
[0057] In one embodiment of the invention, the step of the display device entering the normal display mode includes: obtaining a second control signal and a wide and narrow viewing angle control signal HVA for entering the normal display mode; outputting an enable signal and viewing angle control data according to the second control signal and the wide and narrow viewing angle control signal HVA, so as to provide wide and narrow viewing angle drive signals for the identification area and the non-identification area, so that the display panel can perform normal display with wide and narrow viewing angles.
[0058] Specifically, the normal display mode may include a wide viewing angle display mode and a narrow viewing angle display mode; in the wide viewing angle display mode, the wide and narrow viewing angle control signal HVA may be a low level; in the narrow viewing angle display mode, the wide and narrow viewing angle control signal HVA may be a high level; the wide viewing angle display mode may be switched to the narrow viewing angle display mode by pressing a preset key such as the F2 key. When the processing module 100 obtains a second control signal to enter the normal display mode, for example, when the second control signal is the BL_EN signal and the BL_EN signal is at a high level H, the processing module 100 outputs an enable signal such as the I_EN signal at a high level H to the transformer module 200, and also outputs the corresponding viewing angle control data to the digital-to-analog conversion module 300 via SPI or other transmission methods. The transformer module 200 provides two DC power supply voltages such as +5.2V and -5.2V to the digital-to-analog conversion module 300 according to the enable signal. The digital-to-analog conversion module 300 generates corresponding wide and narrow viewing angle drive signals to the identification area and the non-identification area based on the viewing angle control data and two DC power supply voltages, through the amplification bias of the first voltage amplification unit 410 and the amplification bias of the second voltage amplification unit 420, so that the display panel can display normally at wide and narrow viewing angles. For example, in the wide viewing angle display mode, the first and second viewing angle electrodes (identification area electrodes) in the identification area, and the third and fourth viewing angle electrodes (non-identification area electrodes) in the non-identification area are all applied with wide viewing angle drive signals, such as an AC voltage of a rectangular square wave of ±5V, so that the positive liquid crystal molecules in the first liquid crystal layer of the dimming box are greatly deflected, while the display box is working, and the display panel can achieve normal display at a wide viewing angle. In the narrow viewing angle display mode, the first and second viewing angle electrodes (identification area electrodes) in the identification area, and the third and fourth viewing angle electrodes (non-identification area electrodes) in the non-identification area are all applied with narrow viewing angle drive signals, such as an AC voltage of a rectangular square wave of ±2.6V, so that the positive liquid crystal molecules in the first liquid crystal layer of the dimming box are less deflected, while the display box is working, and the display panel can achieve normal display at a narrow viewing angle.
[0059] Based on the same inventive concept, an embodiment of the present invention further provides a display device. Figure 1 As shown, the display device of this embodiment includes a processing module 100 and a display panel; the processing module 100 is used to execute the above-mentioned identification display method of the display device; the display panel includes a dimming box 510, a display box and a backlight module, and the upper and lower sides of the dimming box 510 are respectively provided with a first polarizer and a semi-transparent semi-reflective film, and the first polarizer is parallel to the transmission axis of the semi-transparent semi-reflective film; the display panel has a logo area and a non-logo area; the dimming box 510 includes a first substrate, a second substrate and a first liquid crystal layer, the first substrate is provided with a common electrode, and the second substrate is provided with a first viewing angle electrode and a second viewing angle electrode (logo area electrode) corresponding to the logo area, and is also provided with a third viewing angle electrode and a fourth viewing angle electrode (non-logo area electrode) corresponding to the non-logo area. For the sake of brief description, for parts not mentioned in this embodiment, please refer to the corresponding content in the above embodiments.
[0060] In one embodiment of the invention, the display device further includes a power module 600; when the display device enters the identification display mode, the power module 600 provides power to the processing module 100. In the identification display mode, because the display device enters the sleep state, hibernation state or shutdown state, the display box in the display panel does not work, and the backlight module does not work. The processing module 100 is only used to control the dimming box 510 in the display panel to work, so there is only very low static power consumption in the identification display mode, about 0.05W. Therefore, a power module 600 can be set up specifically for the identification display mode to better reduce power consumption, such as Figure 1 As shown, the power module 600 is connected to the processing module 100. When the display device enters the logo display mode, the power module 600 provides a voltage such as 3.3V voltage to the processing module 100 to adapt to the lower static power consumption requirement.
[0061] In one embodiment of the invention, the display device further includes a register module, a timing controller, and an interface module. The register module is used to store coded data, which is generated in normal display mode based on the user's selection of a corresponding display mode. The timing controller is used to read the coded data stored in the register module and generate a display mode control signal based on the coded data. The signal is then sent to the processing module 100 via the interface module, so that the processing module 100 can configure the display mode.
[0062] The embodiment of the present invention provides a method for displaying an identification on a display device and a display device. The method for displaying an identification on a display device includes: obtaining a first control signal for a identification display mode when entering a sleep state, a dormant state, or a shutdown state; outputting an enable signal and identification control data according to the first control signal to generate a reflection voltage signal to the identification area electrode, and also generating a non-reflection voltage signal to the non-identification area electrode, so that the ambient light reflected by the semi-transparent and semi-reflective film passes through the identification area corresponding to the identification area electrode, so that the display panel displays the identification content of the identification area. In addition, the identification display mode may also include multiple display modes for the user to select. Thus, the embodiment of the present invention can enter the identification display mode to display the identification content in the sleep state, the dormant state, or the shutdown state, so as to better promote the brand.
