[0177] In Figure 7A, the label Fm is the m-th output inverter, and the label GFm is the m-th inverting drive signal output terminal.
[0178] Figure 7B is a circuit diagram based on Figure 7A with the addition of TGP and TG1.
[0179] In at least one embodiment shown in Figure 7B, during operation, the starting voltage can be written into the starting stage driving circuit in the local display mode, and the control signal transmission direction is forward scanning. This enables the display area above the starting stage to be inactive, so that the pixel circuit corresponding to the m-th stage driving circuit can function as the starting row of the local display area.
[0180] As shown in Figure 7B, in partial display mode, during forward scanning,
[0181] EN_PART provides a high voltage signal, EN_PART' provides a low voltage signal, TGP is turned on, STV and PI are connected, GSD_FW provides a high voltage signal, GSD_BW provides a low voltage signal, TG1 is turned on, STV writes the starting voltage to the m-th input terminal Sm;

[0183] At least one embodiment shown in Figure 7B during operation
[0184] When the starting voltage is input to Sm from TGP and TG1, it will pass through the signal level transmission endpoint. That is, the starting voltage may be transmitted upward or downward. If the starting voltage is transmitted upward, the logic of the starting row module will conflict with the local display requirements. Therefore, in order to ensure that the starting voltage is transmitted stably to the next level, TGS1 is added to the path of transmission to the next level for switching control. Similarly, after the signal passes through DFFm, there is also a signal level transmission starting point between the m-th driving circuit and the (m+1)-th driving circuit. Therefore, TGS2 also needs to be added to the path of transmission to the next level for switching control.
[0185] As shown in Figure 7C, when EN_PART provides a high voltage signal and EN_PART' provides a low voltage signal, the local display mode is entered, TGS1 and TGS2 are both disconnected, thereby controlling the signal transmission direction to be downward.
[0186] When EN_PART provides a low voltage signal and EN_PART' provides a high voltage signal, the global display mode is entered, and both TGS1 and TGS2 are turned on (which can be regarded as two wires). The transmission direction can be selected according to the forward and reverse scanning settings.

[0215] In Figure 11A, the nth output inverter is labeled Fn, and the nth inverting drive signal output terminal is labeled GFn.
[0216] Figure 11A is a circuit diagram of at least one embodiment of the cutoff stage drive circuit.
[0217] In at least one embodiment shown in FIG11A, TGJ1 and TGJ2 are circuit modules for controlling the direction of signal transmission.
[0218] In operation, at least one embodiment shown in FIG11A of this disclosure provides a high voltage signal and EN_PART' provides a low voltage signal in partial display mode. TGJ1 and TGJ2 are turned off, NIn and NJ2 are disconnected, and NTn and NJ1 are disconnected to disconnect the signal transmission path between the nth stage drive circuit and the n+1th stage drive circuit.
[0219] In global display mode, EN_PART provides a low voltage signal, EN_PART' provides a high voltage signal, TGJ1 and TGJ2 are turned on, NIn and NJ2 are connected, and NTn and NJ1 are connected to establish the signal transmission path between the nth stage drive circuit and the (n+1)th stage drive circuit.
[0220] Figure 11B is a circuit diagram based on Figure 11A with the addition of TGP and TG2.
[0221] In Figure 11B, the connection node between TG2 and TGBn is the signal level transmission endpoint between the nth stage drive circuit and the (n+1)th stage drive circuit.
[0222] The connection node between DFFn and TGFn is the signal level transmission point between the nth stage driver circuit and the (n-1)th stage driver circuit.
[0223] In at least one embodiment shown in FIG11B of this disclosure, when the initial voltage is written to Sn during operation, the signal faces three shunt paths: transmission to the next level, entry into DFFn in the nth stage driving circuit, and transmission to the next level.
[0224] When the signal is transmitted to the next higher level driver circuit, logically speaking, the end point of this path is connected to Q_INTER of the (n-1)th level driver circuit. That is, the signal is directly output without passing through the D flip-flop in the (n-1)th level driver circuit. This means that there is no line cycle interval between the nth driving signal output by the nth level driver circuit and the (n-1)th driving signal output by the (n-1)th level driver circuit, resulting in a timing error. From a physical structure perspective, this path is a forward scan transmission path. That is, when the scan mode is reverse scan mode, the forward scan control transmission gate in the (n-1)th level driver circuit is turned off, and the path for the signal to be transmitted from Sn to the next higher level driver circuit is broken.
[0225] When the signal enters the DFFn in the nth stage driver circuit, this path is the expected input path. This is because, as a cutoff stage, it needs to output the current stage driver signal and also transmit the signal level to the input of the D flip-flop in the (n-1)th stage driver circuit in reverse scan mode.
[0226] When the signal is transmitted to the next stage driver circuit, logically, the end point of this path connects to Q_INTER in the (n+1)th stage driver circuit, meaning the signal does not pass through the D flip-flop output in the (n+1)th stage driver circuit, resulting in a timing error. From a physical structure perspective, this path is a reverse scan transmission path. In reverse scan mode, the reverse scan control transmission gate in the (n+1)th stage driver circuit is turned on. Therefore, TGJ2, controlled by EN_PART and EN_PART', needs to be set separately to cut off the signal transmission path. Furthermore, as the last stage driver circuit for partial display, the driver circuits below the cutoff stage driver circuit should not work in partial display mode. Therefore, this path should be disconnected.
[0227] When the signal enters the DFFn in the nth stage driver circuit, it faces two branching paths: transmission to the next stage driver circuit and transmission to the next stage driver circuit.
[0228] Since the cutoff stage driver circuit needs to implement a reverse scan mode, the signal needs to be transmitted to the next higher-level driver circuit.

When EN_PART provides a low voltage signal and EN_PART' provides a high voltage signal, the system enters a global display mode, and the transmission direction is selected according to the forward / reverse scan settings.

[0430] From a product performance perspective, high-resolution devices need to be compatible with low-resolution images and support users' ability to freely adjust resolution to adapt to different application scenarios. For high-resolution devices to be compatible with low-resolution images, directly displaying the actual size of the low-resolution image is the preferred option for maintaining clarity; that is, directly using the corresponding number of pixels to restore the original resolution of the image (displaying the image pixel-for-pixel), resulting in the image appearing only in a portion of the screen's center. Regarding user-adjustable resolution, different users have different display preferences for the same image / video. Providing greater flexibility enhances product competitiveness; for example, video playback could support both full-screen display and in-center display (cinema mode). Therefore, from a product performance perspective, the partial display technology provided in at least one embodiment of this disclosure not only improves the compatibility and versatility of the display product itself but also enhances the user experience.
[0431] In terms of power consumption advantages, the partial display scheme provided in at least one embodiment of this disclosure differs from related partial display schemes in that: traditional partial display schemes display non-partial display areas as black and the partial display area displays the target image; while in at least one embodiment of this disclosure, only the partial display area displays the target image, and the non-partial display areas are inactive. Therefore, compared with related partial display schemes, the driving module described in at least one embodiment of this disclosure has reduced power consumption and can be applied to resource-constrained small silicon-based OLED products.
[0432] Silicon-based OLED (Organic Light Emitting Diode) microdisplays are active-matrix organic light-emitting diode display devices fabricated using single-crystal silicon as the active driving backplane, combining CMOS (Complementary Metal Oxide Semiconductor) technology and OLED technology. Silicon-based OLED microdisplays offer advantages such as ultra-high resolution, high PPI (Pixels Per Inch), high contrast, high brightness, low power consumption, small size, and light weight, making them widely used in AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality), EVF (Electronic Viewfinder), FPV (First Person View, a device based on a wireless camera mounted on a remote-controlled aircraft or vehicle model), drones, thermal imagers, night vision devices, infrared cameras, and medical equipment.
[0433] The above description represents the preferred embodiments of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles described herein, and these improvements and modifications should also be considered within the scope of protection of this disclosure.
