Display Device Lateral Light Source Luminance Compensation

The patent applies local quality by differentiating the drive signals sent to pixels on the first side surface versus pixels on the second side surface. Specifically, the drive circuit sends different gradation values to pixels depending on which side surface they are located on, compensating for the light loss experienced by pixels on the second side surface. This localized adjustment ensures that pixels on the second side surface receive enhanced drive signals to compensate for reduced light intensity, thereby maintaining uniform luminance across all pixels while preserving see-through functionality.

The patent applies preliminary action by pre-compensating for light loss before the light actually traverses the display panel. The drive circuit is configured to send enhanced gradation values to pixels on the second side surface in advance, anticipating the light consumption that will occur as light propagates through the panel elements. This preliminary adjustment ensures that even though light amount decreases during propagation, the pixels on the second side surface still achieve the desired luminance level.

The patent applies parameter changes by modifying the gradation values (drive signal parameters) based on the spatial location of pixels. The drive circuit detects which side surface a pixel is located on and adjusts the gradation value parameter accordingly. Pixels on the second side surface receive higher gradation values to compensate for light loss, while pixels on the first side surface receive standard gradation values. This dynamic parameter adjustment maintains luminance uniformity across the display while preserving see-through functionality.
