Description

【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display device and a driving method thereof. 【Background technique】 [0002] A display device with a camera function includes a display panel and a camera, wherein the display panel is provided with an optical component setting area, and the optical component setting area corresponds to the setting position of the camera. At present, the number of metal wires in the optical component setting area is usually reduced by reducing the pixel density in the optical component setting area, thereby improving the light transmittance of the optical component setting area. However, with this setting method, if the light transmittance of the optical component setting area is to be improved to a greater extent, the pixel density of the optical component setting area can only be set to a small value, which leads to the difference between the optical component setting area and...

Problems solved by technology

However, with this setting method, if you want to increase the light transmittance of the optical component setting area to a greater extent, you can only set the pixel density in the optical component setting area to be very small, which leads to the difference between the optical component setting area and the conventional display. The difference in pixel density in the optical component area is too large, which will cause the optical component setting area to affect the display of the overall screen; if you want to reduce the impact of the optical component setting area on the display, the pixel density in the optical component setting area cannot be too small, which will lead to The light transmittance of the optical component setting area is low, which affects the imaging effect
