Abstract

The invention discloses an OLED display panel and an OLED display device, and the display panel comprises a light-emitting function layer which is used for emitting light, a driving circuit layer stacked with the light-emitting function layer and comprising a plurality of thin film transistor units and at least one photosensitive unit comprising a plurality of light sensing devices used for receiving reflected light after light emitted by the light-emitting functional layer is reflected and converting emitted light into electric signals, and a controller used for receiving the electric signals sent by the light sensing devices; and when the number of the light sensing devices converting the reflected light into the electric signals in the photosensitive unit is larger than or equal to the threshold number, the controller controls the OLED display panel to be touched. According to the OLED display panel, optical touch is achieved through the light sensing device, and the touch reliability of the OLED display panel is improved; meanwhile, the threshold number of the light sensing devices is set, when the number of the light sensing devices converting reflected light into electric signals in the photosensitive unit is larger than or equal to the threshold number, touch control occurs, and the touch control reliability is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] At present, an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel with integrated touch function has become a hot spot for high-end smart products. In recent years, people are pursuing an increasingly thin and light user experience. Due to its unique advantages in manufacturing process, in-cell touch display panels are favored by major panel manufacturers and have evolved into the main development direction of touch technology in the future. [0003] There are two main ways to realize touch in the existing in-cell touch display panel: one is capacitive touch, that is, touch scan lines and touch sensing lines are arranged in the display panel, but because the display panel There is a layer of cathode metal electrodes covering the entire surface. This structure jus...
