[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Furthermore, the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0056] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.
[0057] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of the invention. Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0058] like Figure 1 The diagram shown is a schematic of the internal structure of the driver chip.
[0059] The driver chip includes an interface 10, a digital processor module SR11, a latch 12, a level shift 13, a DAC circuit 14, and an OP circuit 15. After the data is parsed by the interface protocol, it is transmitted to the SR and latch. The level shift converts the data into a high-voltage signal, and then, with the help of the gamma voltage, the DAC circuit performs digital-to-analog conversion, converting the digital signal into a voltage signal corresponding to the grayscale. The OP circuit increases the voltage signal output by the DAC. When the control signal TP arrives, the OP circuit is connected to the pixel unit to drive the pixel unit.
[0060] like Figure 2 The diagram shows the amplification of voltage signals by the DAC and OP circuits inside the driver chip.
[0061] At the rising edge of the TP signal, the DAC circuit begins to convert the data signal, and the voltage of the converted signal begins to rise. The signal output by the OP circuit will rise along with the rising signal output by the DAC circuit. When the falling edge of TP occurs, the data channel between the OP circuit and the display area is turned on, and the voltage of the signal output by the OP circuit will drop briefly. After the brief drop, it will continue to rise along with the voltage of the signal output by the DAC.
[0062] It should be noted that, a such Figure 1 The structure shown corresponds to one data channel, and one data channel corresponds to one display area.
[0063] In this embodiment of the invention, the display screen is divided into several display areas. When a certain display area needs to be displayed, the data channel between the OP circuit and the display area is turned on, and the OP circuit provides a data driving signal to the display area.
[0064] The DAC and OP circuits provide data to drive pixels in the display area in two phases: one is the voltage ramp-up phase, where the output voltages of the DAC and OP circuits increase; the other is the phase where the OP circuit provides the data driving signal to the display area. Figure 2 As can be seen from this, the output voltage of the OP first increases during this stage, and then tends to level off after reaching the target voltage.
[0065] When the display mode is 3D, not all display areas need to be displayed at the same time. The DAC circuit and OP circuit corresponding to the display areas that do not need to be displayed are in an idle state, which results in a waste of resources.
[0066] To address the above problems, embodiments of the present invention provide a driver chip, such as... Figure 3As shown, the driver chip may include a first analog-to-digital converter amplifier circuit (DAC+OP)1, a second analog-to-digital converter amplifier circuit (DAC+OP)2, a first switch SW1, a second switch SW2, a third switch SW3 and a fourth switch SW4;
[0067] One end of the first analog-to-digital converter amplifier circuit (DAC1+OP1) is used to input digital signals, and the other end of the first analog-to-digital converter amplifier circuit (DAC1+OP1) is electrically connected to one end of the first switch SW1 and one end of the second switch SW2. The other end of the first switch SW1 is electrically connected to the pixel of the area to be displayed, and the other end of the second switch SW2 is electrically connected to the pixel of the non-display area.
[0068] One end of the second analog-to-digital converter (DAC2+OP2) is used to receive digital signals. The other end of the second analog-to-digital converter (DAC2+OP2) is electrically connected to one end of the third switch SW3 and one end of the fourth switch SW4. The other end of the third switch SW3 is electrically connected to the pixels of the area to be displayed, and the other end of the fourth switch SW4 is electrically connected to the pixels of the non-display area.
[0069] For example, OP1 corresponds to data channel 1, and OP2 corresponds to data channel 2: ① When no multiplexing is performed, SW1 and SW3 are enabled, and SW2 and SW4 are disabled; ② When data channel 1 multiplexes the DAC time corresponding to OP2, SW1 and SW4 are enabled, and SW2 and SW3 are disabled; ③ When data channel 2 multiplexes the DAC time corresponding to OP1, SW2 and SW3 are enabled, and SW1 and SW4 are disabled.
[0070] It should be noted that, Figure 3 The circuit shown is only an example. In actual implementation, one data channel can reuse multiple DAC+OP circuits. The specific number of DAC+OP circuits reused is not limited in this embodiment of the invention and can be set according to the actual situation.
[0071] To address the aforementioned problems, and in conjunction with the aforementioned driver chip, this embodiment of the invention provides a driving method, such as... Figure 4 As shown, the method includes:
[0072] S401. Based on the distance between the human eye and the display screen and preset rules, determine the display area and non-display area on the display screen;
[0073] S402. Under the control of the control signal, the data signal is converted and amplified using the first analog-to-digital converter amplifier circuit corresponding to the display area and the second analog-to-digital converter amplifier circuit corresponding to the non-display area to generate a data driving signal.
[0074] S403. Provide the driving signal to the area to be displayed to drive the pixels corresponding to the area to be displayed.
[0075] In this embodiment of the invention, when generating the data driving signal, the first analog-to-digital converter amplifier circuit corresponding to the display area and the second analog-to-digital converter amplifier circuit corresponding to the non-display area are used to convert and amplify the digital signal, thereby utilizing the idle amplifier circuit, shortening the voltage signal rise time, and thus improving the display effect and display efficiency while saving resources.
[0076] The embodiments of the present invention are applicable to three-dimensional display mode. In three-dimensional display mode, some areas on the display screen need to be displayed, while some areas do not need to be displayed. The DAC+OP circuits corresponding to the areas that do not need to be displayed are in an idle state.
[0077] In one example, the current mode is determined to be a 3D display mode before determining the area to be displayed and the non-display area on the screen.
[0078] In practice, the display area and non-display area on the display screen are determined based on the distance between the human eye and the display screen and preset rules. First, the coordinate information of the human eye can be determined based on the distance between the human eye and the display screen. Then, the display area and non-display area are determined based on the coordinate information and preset optical refraction display rules.
[0079] In practice, the distance between the human eye and the display screen can be obtained through a camera on the display screen or through sensors. After obtaining the distance between the human eye and the display screen, the coordinate information of the human eye is determined according to a preset algorithm.
[0080] The preset rules in this embodiment of the invention can be a table designed by technicians according to the actual situation. The table represents the pixels seen by the human eye when light is refracted, i.e. the area to be displayed. The coordinate information of different human eyes in the table corresponds to the coordinate information of different areas to be displayed and non-display areas. The areas to be displayed and non-display areas can be determined based on the coordinate information.
[0081] In one example, a first analog-to-digital converter (ADC) amplifier circuit corresponding to the area to be displayed and a second ADC amplifier circuit corresponding to the non-display area are used to convert and amplify the digital signal to generate a data drive signal. The first ADC amplifier circuit can be selected for the data channel corresponding to the area to be displayed within a first duration, and the second ADC amplifier circuit can be selected for the data channel corresponding to the area to be displayed within a second duration. Within the same cycle, the first duration is earlier than the second duration.
[0082] In the above embodiment, since the second analog-to-digital converter amplifier circuit corresponds to the non-display area, the second analog-to-digital converter amplifier circuit is in an idle state at this time. During the second time period, the data channel corresponding to the display area is selected by the second analog-to-digital converter amplifier circuit, so that the data channel corresponding to the display area can reuse the second analog-to-digital converter amplifier circuit, thereby saving resources.
[0083] Combination Figure 3 The driver chip shown can receive control switch on / off control signals sent by the main controller when the data channel is selected, thereby controlling the selection of the analog-to-digital converter amplifier circuit and the data channel.
[0084] For example, there are 16 display areas, located in the left eye's 8-view area. The data entering the human eye is four consecutive view data. Assuming that areas 5, 6, 7, and 8 do not need to be displayed, while areas 1, 2, 3, and 4 do need to be displayed, then according to Table 1, the control instruction is 000. At this time, the main control chip FPGA transmits this control instruction to the driver chip. After receiving the control instruction, the driver chip determines, through Table 1, that areas 1, 2, 3, and 4 need to be displayed, and areas 5, 6, 7, and 8 do not need to be displayed. The driver chip then controls and selects the DAC+OP circuit and data channel corresponding to the areas that do not need to be displayed.

[0086] Table 1
[0087] like Figure 5 The diagram shown is a schematic of the TP control signal provided in an embodiment of the present invention. Figure 5 In the diagram, the dashed line represents the DAC+OP voltage ramp-up, and the solid line represents the provision of data drive signals to the corresponding pixels in the display area.
[0088] Original TP: Under normal circumstances, the process of voltage changing with the TP signal, which provides a driving signal for the pixel, includes the time for the voltage signal output by the DAC+OP circuit to rise and the time for the voltage signal to change after the OP circuit is turned on and the data channel corresponding to the display area is activated.
[0089] By selecting the amplifier circuit corresponding to the non-display area and the data channel corresponding to the display area, the idle DAC+OP circuit is used to amplify the voltage signal. This saves the rise time of the voltage signal output by the DAC+OP circuit, and the saved time can be used in the following two situations:
[0090] Case 1: Under the influence of high resolution or high refresh rate, the voltage of the data drive signal may not be able to rise to the target voltage, resulting in poor display effect. Using the driving method of this invention, the idle DAC+OP circuit is used to increase the voltage. During the voltage rise of the output voltage of the first analog-to-digital converter amplifier circuit DAC1+OP1, the data channel of the second analog-to-digital converter amplifier circuit DAC2+OP2 corresponding to the area to be displayed is turned on. The second analog-to-digital converter amplifier circuit DAC2+OP2 outputs a data drive signal to drive the pixels of the area to be displayed. When the voltage output of the first analog-to-digital converter amplifier circuit DAC1+OP1 rises to the target voltage, the data channel of the first analog-to-digital converter amplifier circuit DAC1+OP1 corresponding to the area to be displayed is turned on, and the data channel of the second analog-to-digital converter amplifier circuit DAC2+OP2 corresponding to the area to be displayed is turned off. The first analog-to-digital converter amplifier circuit DAC1+OP1 outputs a data drive signal to drive the pixels of the area to be displayed, and the output voltage of the second analog-to-digital converter amplifier circuit DAC2+OP2 rises. This process is repeated alternately.
[0091] In this case, the TP frequency is half of the original TP frequency. At this time, the timing control circuit will also make corresponding changes, while the data transmission frequency remains unchanged.
[0092] It should be noted that the above embodiment uses one OP circuit for multiplexing, so the TP frequency is half of the original TP frequency. If two OP circuits are used for multiplexing, the TP frequency is one-third of the original TP frequency, and so on.
[0093] By saving the rise time of DAC+OP, the process of driving the pixels in the display area is used to increase the time for driving the pixels in the display area, which means increasing the time for the voltage of the data drive signal to rise to the target voltage, thereby improving the display effect.
[0094] Case 2: In products that require high frame rates, assuming that there is sufficient time to drive the pixels in the display area, the driving method of this invention reduces the voltage ramp-up time of the DAC+OP, and the frame rate increases accordingly.
[0095] In this scheme, the TP frequency is half of the TP frequency after the refresh frequency is changed. At this time, the timing control circuit needs to make corresponding changes to the timing. Meanwhile, the data transmission frequency is the data transmission rate required after the refresh frequency is changed.
[0096] To facilitate understanding, the following explanation, based on simulation diagrams, illustrates how the present invention improves display quality or increases frame rate.
[0097] Under the conditions of H = 1.22µs, 16kHz, and 60Hz resolution, the DAC multiplexing time is simulated as follows: Figure 6a and Figure 6b As shown:
[0098] Figure 6a This is a simulation diagram before reusing the DAC+OP circuit. Figure 6b This is a simulation diagram of the DAC+OP circuit after multiplexing.
[0099] The near-end signal source is loaded (R = 10K, C = 62pF). The DAC voltage and OP voltage are simulations of the far-end voltage changes, which are related to the pixels in the display area.
[0100] Before using the DAC multiplexing time, the time required for the DAC+OP voltage to climb to 90% of the target voltage is 291ns;
[0101] After using DAC time multiplexing, the time required for the DAC+OP voltage to climb to 90% of the target voltage is 85ns.
[0102] After reuse, the drive time was reduced by 210 ns;
[0103] This is based on a DAC climb time of 300ns;
[0104] Based on the above conditions, the drive rate can be increased from 80% to over 90% or the frame rate can be increased to around 75Hz.
[0105] When using this solution, such as Figure 7 As shown, the data needs to be rearranged;
[0106] Each line of transmitted data contains two lines of actual displayed data (odd and even lines of data).
[0107] Based on the same inventive concept, embodiments of the present invention provide a driving device, such as... Figure 8 As shown, it may include: a region determination circuit 80 and a driver chip 81;
[0108] The area determination circuit 80 is configured to determine the display area and non-display area on the display screen based on the distance between the human eye and the display screen and preset rules;
[0109] The driver chip 81 is configured to, under the control of a control signal, use a first analog-to-digital converter amplifier circuit corresponding to the display area and a second analog-to-digital converter amplifier circuit corresponding to the non-display area to convert and amplify the digital signal to generate a data driving signal; and provide the driving signal to the display area to drive the pixels corresponding to the display area.
[0110] In one example, the region determination circuit 80 is specifically configured as follows:
[0111] The coordinate information of the human eye is determined based on the distance between the human eye and the display screen;
[0112] Based on the coordinate information and preset rules, the area to be displayed and the area not to be displayed are determined.
[0113] In one example, the driver chip 81 is specifically configured as follows:
[0114] The driver chip 81 is specifically configured as follows:
[0115] Within a first time period, the data channel corresponding to the display area is selected by the first analog-to-digital converter amplifier circuit.
[0116] During the second time period, the data channel corresponding to the area to be displayed is selected by the second analog-to-digital converter amplifier circuit.
[0117] Within a single cycle, the first duration precedes the second duration.
[0118] In one example, the device also includes a frequency changing circuit;
[0119] After determining the display area and non-display area on the display screen, and before generating the drive signal to drive the display area, the frequency changing circuit is specifically configured as follows:
[0120] The frequency of the control signal is obtained by changing the frequency of the original control signal based on the number of the second analog-to-digital converter amplifier circuits.
[0121] In one example, the device also includes a pattern determination circuit;
[0122] Before determining the display area and non-display area on the display screen, the mode determination circuit is configured to:
[0123] The current display mode is set to 3D display mode.

[0126] The display panel in this embodiment of the invention can be a liquid crystal display panel, which includes a counter substrate and an array substrate disposed opposite to each other, and a liquid crystal layer located between the counter substrate and the array substrate.
[0127] In specific implementations, in the embodiments of the present invention, the display device can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator. Other essential components of the display device are those that should be understood by those skilled in the art, and will not be described in detail here, nor should they be construed as limiting the present invention.

Specifically, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage and optical storage) containing computer-usable program code.

Because the first ADC amplifier circuit corresponding to the display area and the second ADC amplifier circuit corresponding to the non-display area are used to convert and amplify the digital signal when generating the data driving signal, idle amplifier circuits are utilized, shortening the voltage signal rise time, thereby saving resources while improving display effect and efficiency.
