Problems solved by technology

[0003] At present, the display device generally adopts an external light-sensitive structure to detect the light intensity of the external environment to adjust the brightness of the display screen of the display device, but the external light-sensitive structure will affect the overall space of the display device, which is not conducive to the display of the display device. The expansion of the screen, for example, is not conducive to the realization of the full screen

Abstract

The invention discloses a display panel and a display device. The display panel comprises at least one electric bridge structure, a first light sensation resistor of the electric bridge structure is in series connection between the first voltage signal input end and the first sensing signal output end, a second light sensation resistor of the electric bridge structure is in series connection between the first sensing signal output end and the second voltage signal input end, a third light sensation resistor of the electric bridge structure is in series connection between the first voltage signal input end and the second sensing signal output end, and a fourth light resistor of the electric bridge structure is in series connection between the second sensing signal output end and the secondvoltage signal input end; the ratio of initial resistance values of the first light sensation resistor and the second light sensation resistor is equal to that of initial resistance values of the third light sensation resistor and the fourth light sensation resistor; at least one light sensation resistor in the electric bridge structure is not shielded by a light shielding structure; when the electric bridge structure is effectively illuminated, the ratio of real-time resistance values of the first light sensation resistor and the second light sensation resistor is not equal to that of real-time resistance values of the third light sensation resistor and the fourth light sensation resistor. According to the technical scheme, the influence of temperature on the light sensation detection process is improved while the light sensation detection function of the display panel is enabled.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] The light intensity of the external environment has a great influence on the display effect of the display device. For example, when the display device is in a brighter environment, the display screen of the display device is brighter, but when the display device is in a darker environment, the display The display screen of the device will appear ripple phenomenon, and the display screen is too bright, which may easily cause visual fatigue of the user. In addition, if the display screen of the display device is too dark, the color vividness of the display screen of the display device will be greatly reduced. The brightness of the display screen improves the user's visual comfort. [0003] At present, the display device generally adopts an external light-sensitive structure to detect ...
