## Abstract

A display device has alignment features that compensate for variability in open cells sourced from different vendors. A backlight is arranged behind or beneath an open cell to illuminate picture elements. The open cell and the backlight rest or reside within a cover shield. Because the open cell may have supplier variability, the cover shield has receptacles such as holes or apertures that align with features protruding from a module fixture. The modular fixture thus allows the open cell and the backlight to be arranged, aligned, and/or assembled to the covert shield, despite the supplier variability in the open cell.

## Claims

### Claim 1

A display module, comprising:
an open cell having picture elements;
a backlight for illuminating the picture elements of the open cell;
a lower cover shield mating with a bottom edge of the open cell, the lower cover shield having a bottom longitudinal edge and a receptacle along the bottom longitudinal edge; and
a sliding “L”-shaped modular fixture having a sliding alignment feature sliding along the bottom longitudinal edge of the lower cover shield into an alignment with the receptacle along the lower cover shield.

### Claim 2 (depends on 1)

The display module of claim 1, wherein the sliding “L”-shaped modular fixture further comprises a protruding pin as the sliding alignment feature that slides along the bottom longitudinal edge of the lower cover shield into the alignment with the receptacle along the lower cover shield.

### Claim 3 (depends on 1)

The display module of claim 1, wherein the lower cover shield has multiple receptacles along the bottom longitudinal edge.

### Claim 4 (depends on 1)

The display module of claim 1, wherein the sliding “L”-shaped modular fixture further comprises multiple alignment features.

### Claim 5 (depends on 1)

The display module of claim 1, wherein the sliding “L”-shaped modular fixture further comprises an additional alignment feature.

### Claim 6 (depends on 1)

The display module of claim 1, wherein the sliding “L”-shaped modular fixture further comprises an additional alignment feature that is orthogonal to the sliding alignment feature.

### Claim 7 (depends on 1)

The display module of claim 1, wherein the picture elements comprise liquid crystals.

### Claim 8 (depends on 1)

The display module of claim 1, wherein the backlight comprises liquid crystals.

### Claim 9 (depends on 1)

The display module of claim 1, wherein the backlight comprises light emitting diodes.

### Claim 10 (depends on 1)

The display module of claim 1, further comprising an optical film.

### Claim 11 (depends on 1)

The display module of claim 1, further comprising a decorative branding strip.

### Claim 12 (depends on 1)

The display module of claim 1, further comprising a decorative branding strip affixed to the modular fixture.

### Claim 13

A display device, comprising:
an open cell having picture elements;
a backlight for illuminating the picture elements of the open cell;
a lower cover shield mating with a bottom edge of the open cell, the lower cover shield having a bottom longitudinal edge and a receptacle along the bottom longitudinal edge;
a sliding “L”-shaped modular fixture having a sliding alignment feature sliding along the bottom longitudinal edge of the lower cover shield into an alignment with the receptacle along the cover shield; and
a rear cover mating with the lower cover shield.

### Claim 14 (depends on 13)

The display device of claim 13, further comprising a stand supporting the rear cover.

### Claim 15 (depends on 13)

The display device of claim 13, further comprising a stand pivotably attached to the rear cover.

### Claim 16 (depends on 13)

The display device of claim 13, further comprising a pin that protrudes from the sliding “L”-shaped modular fixture as the sliding alignment feature.

### Claim 17 (depends on 13)

The display device of claim 13, further comprising multiple receptacles in the lower cover shield.

### Claim 18 (depends on 13)

The display device of claim 13, further comprising multiple alignment features in the lower cover shield.

### Claim 19 (depends on 13)

The display device of claim 13, wherein the picture elements comprise liquid crystals.

### Claim 20

A display module, comprising:
an open cell having picture elements;
a backlight for illuminating the picture elements of the open cell;
a lower cover shield mating with a bottom edge of the open cell, the lower cover shield having a bottom longitudinal edge and a plurality of receptacles along the bottom longitudinal edge; and
a sliding “L”-shaped modular fixture having a sliding protruding pin sliding along the bottom longitudinal edge of the lower cover shield into an alignment with a receptacle of the plurality of the receptacles.
