Abstract
Official abstract text for this publication.
The present application relates to a display device that is divided into a first region as a fingerprint recognition region and a second region as a display region with the first region having a first light transmittance greater than a second light transmittance of the second region. The light transmittance of the region corresponding to the fingerprint recognition module group in the display device of the present application can be increased, thereby further improving the sensitivity of the fingerprint recognition module group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display device, comprising a first region as a fingerprint recognition region and a second region as a display region, the first region having a first light transmittance greater than a second light transmittance of the second region, the display device comprises a driving layer comprising first driving units and second driving units, the number of thin film transistors and capacitors constituting each first driving unit is less than the number of thin film transistors and capacitors constituting each second driving unit, and the light transmittance of each first driving unit is greater than the light transmittance of each second driving unit, the first region comprises both the first driving units and the second driving units, and the second region only comprises the second driving units, wherein, in the first region, the first driving units and the second driving units are alternately arranged in a left-and-right direction and in an up-and-down direction. 2. The display device according to claim 1 , wherein the number of light-blocking elements constituting each first driving units is less than the number of light-blocking elements constituting each second driving unit, said light-blocking elements include a source electrode, a drain electrode, a gate electrode, a capacitor electrode, and a wire. 3. The display device according to claim 1 , wherein a sum of projection areas of light-blocking elements constituting each first driving units on a plane of the driving layer is smaller than the sum of the projection areas of the light-blocking elements constituting each second driving units on a plane of the driving layer, said light-blocking elements include a source electrode, a drain electrode, a gate electrode, a capacitor electrode, and a wire.
