[0002] Currently, when installing an overdrive pattern on an LCD screen, the installer's timer cannot synchronize with the computer's graphics processing unit (GPU), resulting in the overdrive pattern not being added at the correct time. This requires a significant amount of time and manpower to determine whether the timing of the installed overdrive pattern is correct.

[0003] Adding the driver screen at the wrong time may cause the insertion time to be too long, resulting in functional errors. Summary of the Invention

The screen generator performs the following steps according to the multiple instructions in the memory: adding a buffer to the memory according to a buffer generation instruction; outputting a screen generation instruction through the buffer; receiving and generating multiple grayscale signals in the buffer according to the screen generation instruction; and sequentially outputting a start grayscale signal, an overdrive grayscale signal, and an end grayscale signal of the multiple grayscale signals through the buffer, wherein each of the multiple grayscale signals corresponds to a fixed stage.

[0006] Another technical aspect of this case is an image generation apparatus method.

[0038] Figure 1This is a block diagram illustrating an image generating apparatus according to an embodiment of the present invention. As shown, the image generating apparatus 100 includes a memory 110 and a screen generator 120. In terms of connection, the memory 110 is coupled to the screen generator 120.

[0039] To achieve the correct grayscale display time in overdrive, this case provides the following... Figure 1 The detailed operation of the image generating apparatus 100 shown is described below.

[0040] Figure 2 This is a usage scenario diagram illustrating an image generating device according to an embodiment of this case. Please refer to it as well. Figure 1 and Figure 2 In one embodiment, memory 110 is used to store multiple instructions. A screen generator 120 is used to perform the following steps based on the multiple instructions in memory 110: adding a buffer 111 to memory 110 according to a buffer generation instruction. For example, screen generator 120 can add a buffer 111 to memory 110 as needed, and screen generator 120 can be written in a programming language, such as Microsoft Direct, but this is not a limitation. Furthermore, screen generator 120 can be coupled and communicate with a graphics processing unit (GPU) to further achieve signal synchronization.

[0041] In one embodiment, the image generator 120 is configured to perform the following steps according to multiple instructions from the memory 110: outputting an image generation instruction through the buffer 111; receiving and generating multiple grayscale signals in the buffer 111 according to the image generation instruction. For example, the image generator 120 may continuously generate (or update) multiple grayscale signals in the buffer 111 according to the image generation instruction, and the image generator 120 may generate only one grayscale signal at a time, but this is not a limitation of the present invention.

[0042] In one embodiment, the image generator 120 is configured to perform the following steps according to multiple instructions from the memory 110: sequentially outputting a start grayscale signal 210, an overdrive grayscale signal 220, and an end grayscale signal 230 of multiple grayscale signals through the buffer 111, with each of the multiple grayscale signals corresponding to a fixed stage. For example, the start grayscale signal 210 can be a first pattern, such as a black image corresponding to grayscale 0; the end grayscale signal 230 can be a second pattern, such as a gray image corresponding to grayscale 120; and the overdrive grayscale signal 220 can be an overdrive pattern, such as a light gray image corresponding to grayscale 150, but this embodiment is not limited thereto. Furthermore, the fixed stage can be one frame time, with each of the multiple grayscale signals—the first grayscale signal 210, the overdrive grayscale signal 220, and the end grayscale signal 230—corresponding to one frame time.

[0043] In one embodiment, the display 900 is used to receive and display a start grayscale signal 210, an overdrive grayscale signal 220, and an end grayscale signal 230 of multiple grayscale signals. For example, when the update frequency of the display 900 is 60 Hz, the corresponding frame time is 16.67 ms. Therefore, the time for the display 900 to display the grayscale signals of multiple grayscale signals, the start grayscale signal 210, the overdrive grayscale signal 220, or the end grayscale signal 230 once is 16.67 ms, but this embodiment is not limited to this. In addition, the display 900 can display only one frame at a time. After displaying the first frame (e.g., the start grayscale signal 210), it can wait for the next frame (e.g., the overdrive grayscale signal 220) to arrive before displaying it.

[0044] Figure 3 This is a usage scenario diagram illustrating an image generating apparatus according to an embodiment of this case. Please refer to... Figure 3 In one embodiment, the multiple grayscale signals include four endpoint signals A1 to A4, which constitute two triangle signals 311 and 313. The two triangle signals 311 and 313 constitute one of the multiple grayscale signals (e.g., grayscale signal 310). For example, the four endpoint signals A1 to A4 can constitute two triangle signals 311 and 313, which can further constitute grayscale signal 310, start grayscale signal 210, overdrive grayscale signal 220, or end grayscale signal 230 of the multiple grayscale signals, but this invention is not limited thereto.

[0045] Figure 4This is a schematic diagram illustrating the waveforms of multiple grayscale signals of an image generating apparatus according to an embodiment of this case. Please refer to it as well. Figure 2 and Figure 4 In one embodiment, the overdriven grayscale number of the overdriven grayscale signal 220 is greater than at least one of the starting grayscale number of the starting grayscale signal 210 and the ending grayscale number of the ending grayscale signal 230. For example, Figure 4 The waveform diagram shown can be a schematic diagram of multiple grayscale signals displayed on an oscilloscope. The horizontal axis of this waveform diagram can be time, and the vertical axis can be the number of grayscale levels. In the first stage T1, the signal can be multiple starting grayscale signals 210, and the corresponding overdrive grayscale level can be 150 grayscale levels. In the second stage T2, the signal can be an overdrive grayscale signal 220, and the corresponding starting grayscale level can be 0 grayscale levels. In the third stage T3, the signal can be multiple ending grayscale signals 230, and the corresponding ending grayscale level can be 120 grayscale levels. However, this case is not limited to this.

[0046] In some embodiments, if the refresh rate of the display 900 is 60 Hz, the start grayscale signal 210, the overdrive grayscale signal 220, and the end grayscale signal 230 each correspond to one frame time, and this frame time can be 16.67 ms. Furthermore, the second stage T2 corresponding to the overdrive grayscale signal 220 can be one frame time, that is, the display 900 receives the overdrive grayscale signal 220 once from the buffer 111. Then, the first stage T1 corresponding to the start grayscale signal 210 can be 10 frame times, that is, T1 = 10 × T2, that is, the display 900 receives the start grayscale signal 210 ten times from the buffer 111. Then, the third stage T3 corresponding to the end grayscale signal 230 can be 10 frame times, that is, T3 = 10 × T2, that is, the display 900 receives the end grayscale signal 230 ten times from the buffer 111. However, this invention is not limited to this.

[0047] In one embodiment, the display time of the display 900 is related to the refresh rate of the display 900 and multiple grayscale signals. For example, the display time can be... That is, the frame time multiplied by (the number of times the grayscale signal is displayed). If the first stage T1 is to display 500ms, then the refresh rate of monitor 900 can be 60Hz, and the frame time is 16.67Hz. Therefore, the number of times the initial grayscale signal 210 is displayed on monitor 900 can be... However, this case is not limited to this.
