Abstract
A functional module is applied in a front light module of a display device. The functional module includes a composite cover structure having a first plate and a second plate and a reflective display panel. The second plate is located between the first plate and the reflective display panel. At least one medium layer is located between the first plate of the composite cover structure and the reflective display panel. The refractive index of the medium layer is greater than or equal to 1 and is smaller than 1.474.
Claims7
A functional module, applied in a front light module of a display device, comprising:
- a composite cover structure having a first plate and a second plate;
- a reflective display panel, wherein the second plate is located between the first plate and the reflective display panel;
- a touch module having an electrode layer and a touch layer below the electrode layer, wherein the electrode layer is located between the second plate of the composite cover structure and the touch layer, and the touch layer is located between the electrode layer and the reflective display panel;
- and
- at least two medium layers located between the first plate of the composite cover structure and the reflective display panel, wherein the refractive index of the medium layers is greater than or equal to 1 and is smaller than 1.474, the touch module is located between the composite cover structure and the reflective display panel, one of the medium layers is located between the first plate and the second plate, and another one of the medium layers is located between the touch module and the reflective display panel.
A display device, comprising:
- a front light module having a light guide plate and a light source;
- and
- a functional module, comprising:
- a composite cover structure having a first plate and a second plate;
- a reflective display panel, wherein the front light module is located between the first plate and the reflective display panel;
- a touch module having an electrode layer and a touch layer below the electrode layer, wherein the electrode layer is located between the second plate of the composite cover structure and the touch layer, and the touch layer is located between the electrode layer and the reflective display panel;
- and
- at least two medium layers located between the first plate of the composite cover structure and the light guide plate, wherein the refractive index of the medium layers is greater than or equal to 1 and is smaller than 1.474, the touch module is located between the composite cover structure and the light guide plate, one of the medium layers is located between the second plate and the touch module, and another one of the medium layers is located between the touch module and the light guide plate.
